Firestorm 6.6.8: Profiles, Local Mesh and more

On Monday January 16th, 2023 (PDT), the Firestorm team released version 6.6.8 of their viewer.

This is another release which might be described as more a maintenance update, intended to keep Firestorm in step with the current official viewer code base, together with  focus on bug fixes more than new features.

However, that said, there are some significant updates to be found in this release, both from Linden Lab (as with the incorporation of Legacy Profiles) and also from the Firestorm Team (notably the Mesh Preview Upload by Beq  Janus).

So, without further ado, lets get into things and see what’s what. And please note that as per all my articles on viewer updates and releases, this is not a full blow-by-blow breakdown of absolutely everything in the release; rather, it is intended to highlight the more significant updates and fixes people are liable to find useful, and offer some general notes .

  • There is no need to perform a clean install with this release if you do not wish to.
  • Do, however, make sure you back-up all your settings safely so you can restore them after installing 6.6.8.

Linden Lab Updates

Firestorm is fully merged up to the  Linden 6.6.7 code-base, plus some cherry-picked items from upstream, per the notes below.

Hotfix Releases

  • MFA / ToS Hotfix, viewer version, November 2022 – ensures the viewer correctly required a double-entry of MFA tokens on launching the viewer and on accepting a Terms of Service update.
  • Modal Hot Fix, viewer version, September 2022 – correcting a crasher within the viewer code.

Maintenance Nomayo Viewer Updates

Viewer version, October 2022.

  • New Mini-Map options: Right click Mini-Map → North at top, Camera at top.
  • Hovering over the Mini Map now shows ownership information for the given parcel.
  • Fixed the right click freeze – BUG-232466FIRE-31927.
  • Fixed Texture position changes while using a HUD only updates after zooming out, BUG-232364.
  • Landmarks should now work more like other assets for cut/copy actions.
  • Animation uploads have joint name fixes.
  • Improved media playback responsiveness.
  • Crash fixes.

Nomayo Hotfix

Viewer version, October 2022.

Maintenance Izzara Viewer Updates

Viewer version, September 2022.

  • Improved reporting of spam and phishing attempts from the Group Chat and IM window with the addition of Report Abuse right-click option
  • Improved land sale option: when selling land, Sell land to “specific person” will show your own name in the “Near Me” list in the people picker – BUG-231954.
  • Ability to restrict media on a prim to this parcel via World → Parcel Details → Sound → Obscure MOAP – BUG-10416.
  • Media on a Prim fixes: media will no longer loop when it should not; audio for media no longer plays when the object is edited.
  • Fixed the Search floater opening without appropriate search results after performing a search from the NavBar
  • Fixed the “360 snapshot” floater not being refreshed after second clicking on the “World” → “360 snapshot” menu item.

Legacy Profiles

In 2022, Linden Lab made the formal transition back to present avatar profiles through an integrated floater within the viewer with the promotion of viewer version was promoted to de facto release status in August of that year (although the web-based version of profiles can still be accessed – with reduced functionality – via

With Firestorm 6.6.8, Firestorm incorporates the Lab’s Legacy Profiles code into their existing Profiles floater, with some changes to the latter as noted below.

Firestorm Profiles floater: as it was (l) and as it is with Firestorm 6.6.8 (onwards) (r)
  1. These tabs / options / buttons have been renamed, but the functions remain the same, unless noted below. Note that Interests has been removed.
  2. The Web tab is renamed Feed and displays the user’s Second Life Feed (under
  3. 2nd Life and 1st Life tab images:
    • The 2nd Life Profile picture has a revised aspect ratio.
    • Within your own profile: clicking the image swatch in either will open a texture picker, allowing you to select an image for either.
    • Within your own 1st Life tab are three buttons:
      • Upload Photo – allows you to upload an image from your computer to the 1st Life Tab to preview it (image must still be uploaded to inventory and applied, if it is to be saved & used).
      • Change Photo – opens a texture picker, allowing you to select an image from inventory to add to your 1st Life tab.
      • Remove Photo – removes any displayed image from the swatch.
  4. Display Name / Multi-option button:
    • When viewing your own Profile, the tool button to open the Display Name edit fields is opened.
    • When viewing the Profile of a Friend, displays a pop-up with the following check-box options:
      • See when I’m online.
      • Find me on the world map.
      • Edit, delete or take my objects.
      • Note that active options will appear in white on the displayed profile, and inactive will appear greyed out, for eas of reference.
    • When viewing the Profile on a non-Friend, this area is blank.
  5. Unknown: a new status option (alongside Online and Offline), displayed when the person concerned is not someone you have friended, and who has their viewer set to only show their on-line status to friends.
    • In addition, and to reduce drama, if a Friend is hiding their status, they will show as Offline, rather than the status in their Profile being blank.

Firestorm Updates and Improvements

Github Actions

Firestorm 6.6.8 is the first set of releases built through the GitHub Actions infrastructure rather than depending on individual developers. This is a significant shift in emphasis for viewer development – and one mirroring moves being made in the same direction by Linden Lab. Benefits include removal of single-person for feature development and providing a more reliable, repeatable build mechanism.

Building and Scripting – Local Mesh (Beta)

Firestorm 6.6.8 introduces Local Mesh as a beta implementation. Developed by Beq Janus, Local Mesh is intended to allow users able to upload mesh to preview their objects in-world (using a “surrogate” object, which can be as simple as a cube prim), and also see edits made to the .DAE file in real time.

  • The primary aim of this capability is to allow creators check their creations without having to go through the unpredictability of access to Aditi (the Beta grid) for such checks / tests, as well as presenting that real-time viewing of edits to the .DAE file.
  • The capability works for unrigged mesh, worn rigged mesh and Animesh, and once rendered, the object can have textures and materials applied for testing, as required.

Local Mesh follows the same basic principles as Local Textures, notably:

  • Meshes are only visible to you through the viewer instance used to apply them.
  • Meshes only remain visible to you during the current log-in session. A relog will both clear the list of Local Mesh Assets and reduce the “surrogate” object for any local mesh you have “rezzed” in-world to a basic shape.

Local Mesh is accessed via the Build menu: Build → Local Mesh, which in turn opens a new floater, comprising 3 tabs.

Local Mesh Assets Tab

Displays the current list of .DAE files obtained from your computer which are available for potential rendering in-world to view. Objects are listed in the middle section of the tab, together with their assigned LODs. When more that one file is listed, the highlighted file name is the one that will be acted upon.

This tab includes the following buttons:

  • Add: opens a file picker and allows you to navigate to and select a .DAE file from your computer. When the file is selected and Open in the picker is clicked, the file is added to the list of available .DAE files.
  • Remove: will remove the highlighted .DAE file from the Local Mesh Assets list and should clears any corresponding in-world object.
  • Reload: Re-loads the selected file in the Local Mesh list and reapplies it to the Mesh object inworld so use this to applies the most recent edits to your .DAE file to your in-world object.
  • Clear: Reverts a selected Local Mesh object inworld to it’s normal state (so, if a cube prim was used, the object will revert to a cube).
  •  Apply: if you have a suitable mesh in-world yo can select it and click this button to apply the properties of the file highlighted in Local Mesh Assets to it.
  • Rez Selected: will prompt you to rez a primitive in-world (via the Build floater, and then applies the properties of the file highlighted in Local Mesh Assets to the rezzed prim.
The Local Mesh workflow
Log Tab
  • Logging for Local Mesh
  • If the status of your Local Mesh file in the Local Mesh Assets list shows “Error” instead of “Active”, check the log for the cause of the error.
Settings Tab
  • Assume scale is in metres:- Ignore the cm scale units used by tools such as Maya,
  • LOD Suffixes: Choose a standard or manually edit
    • SL Standard – Lowest is LOD0, High has no suffix
    • Game Engine Standard – Unity.UES etc, Lowest is LOD3, High is LOD0
    • LOD names – English LOD names, Lowest is LOWEST, High is HIGH
Converting a Local Mesh to a Local Animesh
  • Right-click → Edit the required local mesh (in-world or worn).
  • Add your animations and control scripts to the object.
  • Select the Features tab in the Build floater and check the Animated Mesh option.
Additional Information

For a complete overview of Local Mesh functionality, please refer to Announcing Local Mesh, by Beq Janus, principal developer of the capability, and which can be found on her blog – which is a must-read for anyone interested in content creation and the technicalities of Second Life. In addition, the ? button of the Local Mesh floater will display web-based Help pages based on the floater tab in which the ? button is clicked.

Building and Scripting – General Updates

  • Build Floater: 
    • Face selection cycle now starts at face 1 instead of face 0 – FIRE-32282.
    • Shift+clicking the link/faces button now includes the next face/link into the selection (Build → Select Elements → “Include next part or face” / “Include previous part or face”) – BUG-232757.
  • Physics updates:
    • Mesh physics options in mesh upload preview floater
    • The bounding box now sets a physics cube around the entire mesh even if it is multi part in the mesh uplaoder.
    • eshes with a hull based (non triangle) user physics will not be convexified when scaled to below 0.5m – BUG-232869 and FIRE-32359.
  • Animation upload preview on own avatar should no longer fail when the Firestorm AO is enabled – FIRE-32315.

Firestorm 6.6.3: performance improvements

On Friday, September 9th, 2022 (PDT), the Firestorm team released version 6.6.3 of their viewer – the first such release since indicating they would be stepping up the cadence of releases with more in the way of “maintenance” cycles in order to better keep place with updates and improvements coming out of Linden Lab with the core viewer code.

Whilst technically a maintenance release, version 6.6.3 is significant for Firestorm users as it includes the Lab’s Performance Improvements code, which for this user yielded noticeable performance improvements in terms of general FPS. In addition, there are a number of additional updates from both the Lab and the Firestorm team.

Table of Contents

As per usual, this article is a not a full blow-by-blow breakdown of absolutely everything in this release, but it does include notes on some of the more significant updates and fixes people are liable to find useful, and some general notes.

  • These changes include updates to Vsync (vertical synchronisation):
    • Vsync can now be toggled on / off via Preferences → Graphics → Hardware Settings.
    • When enabled, Vsync will synchronise (/cap) frame rates to your monitor screen refresh rate (e.g. if you have a 60 Hz screen, FPS will be capped at 60 fps) and should deliver smoother game-play.
  • The Performance Improvements viewer also includes the MeshOptimizer Project .
    • By default, this replaces obsolete GLOD’s mesh simplification in the mesh uploader with the newer and more powerful MeshOptimizer package to provide better level of detail (LOD) modelling during the upload process.
    • Note that as an option, Firestorm also retains the GLOD capability – see below for more.

Tracy integration Viewer Updates

Viewer version, November 2021.

  • This update adds the Tracy Profiler to the viewer to help developers interested in or working on performance improvements. For developers/self-compilers:
    • Running autobuild configured with –tracy will enable the telemetry.
    • At any time while running the telemetry recording can be disabled/minimised by deactivating it using the Developer menu entry profiling/telemetry → Profiling .
  • It contains no other user-visible changes.

Firestorm Updates and Improvements

UI Updates and Improvements

Notecards – Font Style, Size and Colour

Firestorm 6.6.3 brings the following capabilities to Notecards:

  • Set the font style and size:
    • Style: one of San Serif, Monospace, Scripting or Cascadia Code.
    • Size: one of Monospace, Scripting, Cascadia Code, Small, Medium or Large.

  • Set the colour of: a notecard background, text, cursor and highlighted text.
    • Set via Preferences → Colors → Miscellaneous → Notecard Colors .

Note: these setting will only apply to notecards you view in Firestorm. Other users will see the notecards you send in whatever font / colours (if the latter can be set should the FS code be adopted by other TPVs) set within their viewer.

Other UI Updates
  • Inventory:
    • It is now possible to open Inventory folders in their own floaters. Right click an inventory folder → Show in new window.
    • The selection count is  now given when deleting multiple items from inventory (FIRE-31816).
With Firestorm 6.6.3 you can open an inventory folder in its own floater
  • The Create Landmark floater (menu bar → World → Landmark this Place) will now open centred on the viewer window by default.
  • 360-degree snapshot floater should now open at last-used quality setting  in a session.
  • Region Details → Region should now:
    • Show the correct length of the region name text (no truncations).
    • Report the correct grid position for the region.

Avatar and Appearance

  • Avatar:
    • The avatar should now turn the full 180-degrees when editing appearance (FIRE-31959 / BUG-232502).
    • All mesh bodies/objects should now show in the shape editor previews (FIRE-31966 / BUG-232503).
    • Animesh attachments should no longer show in shape editor previews.

    • Attempted fix for mesh attachments sometimes vanishing after teleports which should either fix / reduce the number of cases where this may occur (FIRE-31906).
    • Update to the warning given when attaching rigged meshes to HUD.
      • The new message reads: “An attachment named ”[NAME]“ contains rigged mesh but is attached to the HUD point ”[HUD POINT]“,/a>
      • Attaching rigged meshes to HUD was never supposed to be supported, per BUG-232489.
      • Also see: FIRE-31955.

Building and Scripting Updates

GLOD Option In Mesh Uploader

As noted above, Linden Lab introduced Mesh Optimizer as a new way to generate improved level of detail (LOD) models for mesh uploads. However, this can lead to higher upload costs and can cause issues in maintaining UV layout. To help prevent issues Firestorm 6.6.3 retains GLOD alongside of Mesh Optimizer.

To this end the Firestorm mesh uploader presents the following options when specifying a model’s LOD:

  • Load from file: Manually upload .DAE files for models at any level of detail. This enables you to control how your model looks at each level of detail, preserving key visual features that the automated algorithms may otherwise distort. If the viewer could “auto-detect” lower LOD models when it first loaded the model, these will be shown in the corresponding LOD “slots” here.
  • Generate Auto: Generate a new model at the currently previewed level of detail based on the model you uploaded. This method currently defaults to using the sloppy method and tries to set a target number of triangles based upon the high LOD. This is the method applied when first selecting your model if no auto-detected LODs are found.
  • Generate Precise: Uses the newer method (Mesh Optimizer) to construct a LOD model. This is more accurate than the “sloppy” method but will result in a more detailed model. Target triangle settings and thresholds are very loosely adhered to.
  • Generate Sloppy: Uses the newer method (Mesh Optimizer) to construct a LOD model. The “sloppiness” relates to the accuracy of the result compared with the original. Target triangle settings and thresholds are very loosely adhered to .
  • Generate Reliable: Uses the older method (GLOD) to construct a LOD model. This method is what we have been used to in the past; it gives reliable results based upon the target settings.

For more information, please refer to: Mesh Upload – Level of Detail.

Other Building / Scripting Related Updates
  • The “remaining capacity” LI count has been returned to the Edit / Build floater.
  • Flip texture scale buttons should no longer “magically jump” when switching texture modes.
  • The animation preview window should now have a link to the correct wiki page (FIRE-31836).
  • Full bright rigged meshes should now correctly display as full bright.
  • Full bright transparent objects should no longer render as solid when using highlight transparent – CTRL-ALT-T (FIRE-31986).
  • 100% transparent objects on HUDs should now show when highlighting transparent – CTRL-ALT-T (FIRE-31917).
  • The Firestorm Bridge can now display object rez time with the Script info in extended info mode (enabled via Preferences → Firestorm → Build 2 → Enable extended script info details).

Other Updates of Note + Key Fixes

Third-Party Library + RLV Updates

  • FMOD Studio updated to version to 2.02.07.
  • Updated Collada with a C++17 compatible version.
  • Firestorm 6.6.3 is running Restrained Love API RLV v3.4.3 / RLVa v2.4.2.67470, and includes a fix for focus going unexpectedly to menu bar after calling llMapDestination with “@showworldmap=n” (FIRE-31920).

Linux Updates

  • 3p Library Updates:
    • Boost updated to boost-1.72-linux64-222121224.
    • Collada updated to colladadom-2.3.222130404-linux64-222130404.
    • Curl updated to curl-
    • Libxml updated to libxml2-
    • Meshoptimizer updated to meshoptimizer-0.16.222121104-linux64-222121104.
    • Minizip updated to minizip_ng-
  • New Simple DirectMedia Layer-2 (SDL2) support for Linux to future-proof Firestorm, providing better low-level access to audio, keyboard, mouse, joystick, and graphics hardware via OpenGL and Direct3D. See the SDL2 Documentation.
  • The Linux viewer now uses xdg-open ahead of x-www-browser, as requested in FIRE-31929.

OpenSim Updates

There are no OpenSim updates with Firestorm 6.6.3.

Key Fixes

  • FIRE-31852 – Modified hotkey gestures should no longer play from any window.
  • FIRE-31823 / FIRE-31648 – torn-off menus should now correctly update enabled/visible state
  • FIRE-31882, FIRE-31896 / BUG-232463 – The main menu bar should no longer become the focus when minimising docked floater or after changing graphics preset
  • FIRE-31913 – CTRL+Tab should now correctly switch to the active floater.
  • Crash fixes:
    • FIRE-31818 – Firestorm should not longer crash when inspecting a Linden tree.
    • FIRE-31942 – Firestorm should no longer crash when taking a 360 snapshot when “Improve graphics speed” is enabled – note that this may mean that slower machines timeout during a 360 snapshot, so a new debug setting FSUseCoRoFor360Capture – Use co-routine to extract 360 photos – has been added. By default, this is set to False to prevent crashing. Setting it to True may result in crashes.
    • FIRE-31473 – “Internal Error”/“Uncaught Exception”.
  • Again, please refer to the 6.6.3 release notes for the full list of fixes with this release.


As noted towards the top of this article, Firestorm 6.6.3 is the first release of the viewer since the Firestorm team moved towards a faster release cadence, allowing the viewer to pretty much reached parity with the official viewer, which should ease matters of parity going forward, assuming a 6-8 week release cadence can be maintained – and hopefully, it will be.

Probably the most significant inclusion in this release is that of the Lab’s updated viewer code and thread handling, intended to improve general performance. As I noted at the time this code reached release status in the official viewer, this code gave me an average boost of around 20 fps compared to a version without the improvements; in comparing Firestorm 6.5.6 and 6.6.3, I noted a similar fps boost. This is also the first viewer I’ve ready played around with the updated Vsync functionality, and have found that it does offer a far smoother experience for me when flycamming.

Elsewise, I’ve not had a a lot of time to test this release, but have found it to be stable during my personal use, so those updating may want to keep an eye on the Firestorm in-world support groups and the Jira for info on any possible issues.

Firestorm 6.5.6: maintenance refresh!


On Monday, July 25th, 2022, the Firestorm team released version 6.5.6 of their viewer.

This is very much a maintenance update for Firestorm rather than a major release; the focus is very much on bug fixes rather than new features.

That said, it does bring Firestorm closer to the official release viewer, incorporating as t does the April and May official viewer releases code – so with this release, Firestorm embraces multi-factor authentication.

Table of Contents

As per usual, this article is a not a full blow-by-blow breakdown of absolutely everything in this release, but it does include notes on some of the more significant updates and fixes people are liable to find useful, and some general notes.

For a complete breakdown of changes, please see the official release notes for Firestorm 6.5.6.


  • There is no need to perform a clean install with this release if you do not wish to.
  • Do, however, make sure you back-up all your settings safely so you can restore them after installing 6.5.6.

Linden Lab Updates

This release brings Firestorm up to parity with the following Linden Lab viewer releases:

  • Lao-Lao Maintenance Release viewer (version, dated April 18th, 2022) containing numerous bug fixes).
    • One notable fix in this viewer is for photographers, correcting as  it does – BUG-231868 “[MAINT J+K] 360 Snapshot tool fails to save file to computer (Mac and Windows)”
  • The MFA Release viewer (version, dated May 4th), which rolled multi-factor authentication to the viewer – see below for more.

In addition, Firestorm 6.5.6 includes support for the release of Premium Plus (increased Group allowance, etc).

Multi-Factor Authentication

Firestorm 6.5.6 incorporates Linden Lab’s viewer-side Multi-Factor Authentication (MFA) code. This provides additional security to your Second Life account both through the web (e.g. trying to view your billing info or transaction history, trying to cash out (“process credit”) money out of your account, trying to change the e-mail address associated with your account, etc.), and in accessing your account using the viewer. It is entirely optional, and you do not need to use it if you don’t want to – although usage is recommended.

You can find out more on MFA in general by following the links below:

Inclusion of MFA in a viewer means that anyone who has opted to use MFA

  • Will, the first time they use Firestorm 6.5.6, have to use their preferred authentication method (e.g. Google Authenticator) to generate a new token (6-digit code) and enter it into the viewer when prompted (after entering their user name and password).
The MFA prompt for a token, which will be seen in Firestorm 6.5.6 (and other viewers supporting the Lab’s MFA code) once every 30 days.
    • Note that some authenticators generate their token as 2 groups of 3 digits (e.g. XXX  YYY). Where this is the case, you can enter the code with or without the space.
  • This token will remain valid for 30 days, as noted above, so you do not have to provide a token every time you log-in to the viewer.
    • However, after 30 days, the prompt will once again be displayed at log-in, and a new token code will have to be generated in the chosen authentication method, and entered into the viewer in response to the prompt.

If you have not opted to use MFA, or if you later opt to disable MFA on your account, you will not be prompted to provide any authentication code.

Firestorm Updates and Improvements


The Shared Environment button on Phototools works with Firestorm 6.5.6

A minor, but nevertheless issue with Phototools since the introduction of the Environmental Enhancement Project (EEP) capabilities into Firestorm has been the fact that the Shared Environment button (Phototools → Env) has never been properly hooked-up to the EEP controls.

It’s a niggle I pointed to at the time that Firestorm released with EEP incorporated but – and shame on me for not doing so – I never got around to raising a bug report on it.

Fortunately, Spartaco Zemenis did Jira it (see FIRE-31688), with the result that the button has now been properly hooked-in to EEP and clicking it (as with clicking the X button alongside of Personal Lighting) will now revert your viewer’s environment settings to those set for the region / parcel you are current in.

And the difference between the two? X will perform a transition between whatever your current environment settings are and those used within the region / parcel; the Shared Environment button will simple switch the viewer to using the local environment settings without any transition effects.

Skin Updates

  • The Legacy Skin has been removed as a result of being unmaintained for so long.
  • The Starlight and Starlight CUI have been updated, and now includes a fix for FIRE-30839 “Camera window not fully opaque at 1.00 and doesn’t have StarLight & Silver Blue support”.

Other Updates and Fixes


  • The “Avatars Nearby” list in the performance floater now respects display name/username choice (set via Preferences → General).
  • New physics warning to the mesh uploader when model dimensions are too thin. Mesh-based physics reverts to convex hull when any single dimension goes below 0.5m, so new warning added should this occur:
    • One or more dimensions is less than 0.5m, only hull-based (analysed) physics shapes will work correctly.
  • Debug Setting update: BrowserWebSecurityDisabled – disables web security features in the built-in Web browser.
  • Firestorm Bridge now uses HTTPS by default.
  • BUG-231970 “LOD generation does not trigger a refresh” (also fixed in the lab’s Performance Improvement viewer).
  • FIRE-31074 “Double Click Teleport Stuck On, And Ignoring Modifiers”.
  • FIRE-31552 “Glowing, 100% transparent prims no longer glow”.
  • FIRE-31687 “Overlapped windows when you create a pick on the Places floater”.
  • FIRE-31689 “Wrong folder is shown when creating a LM”.
  • FIRE-31322 “[Linux] Growl notifications do not show in Gnome 41 or Gnome 42 (Desktop Environment)”.
  • FIRE-31758 “RLVa: Area Search shows nametags when restrictions in place”.
  • FIRE-21700 “Full bright not adhering when gamma changed”.
  • FIRE-31719 “Store camera view fails in Flycam mode”.
  • FIRE-31406 “FS Guidebook pane while loading clips content too much”.
  • FIRE-31472 “When using the Improve Graphic Performance floater some aspects will not work when Framerate Limiter is active”.
  • Nearby blocked avatars should no longer cause the viewer to randomly hang.
  • Adds a warning toast as a reminder when there is a scripted followcam active that might stop a camera reset when trying to use SHIFT+ESC to reset camera view.

Crash Fixes

  • FIRE-31474 “Importing linkset crashes while uploading textures” .
  • FIRE-31653 “Pressing CTRL + F with “banned” list open in any group profile crashes the viewer to desktop”.
  • FIRE-31482 “Crashing To Desktop While Using [Legacy events] Search”.

Future Releases

In the past, the Firestorm team has tried to maintain a two-month QA cycle: starting a month after a release, QA on the nest would start with beta testing. This would be followed in the 6th week of the beta cycle by the issuing of a “Release Candidate” for additional testing the the Firestorm Preview Group. Due to the numbers involved in the Preview Group, issues would be found very late in the QA cycle, leading to delays in the release being made.

To try to prevent this in the future, Firestorm is moving to a process of pre-release building being issued to the Preview Group on a weekly basis, monitored by the QA team, working with the Preview Group users in determining what is a bug that should be reported vs what may be an artefact of something unrelated, like a user setting, that can be corrected without the need for exhaustive bug reporting and testing. This will hopefully result in a more frequent release process.

Firestorm 6.5.3: performance and photos (and more!)

On Monday, March 21st, 2022, the Firestorm team released version 6.5.3 of their viewer.

This is a significant update to Firestorm, containing major new elements aimed at helping to improve viewer performance / the user experience.  As such, these elements for the major focus for the notes below.

As per usual, it also brings Firestorm closer to the current official SL release viewer by including a number of updates and capabilities previously released by LL. Again, from an end-user perspective, one of the most noticeable of this is likely to the incorporation of the 360º snapshot capability,  which is also looked at in detail below.

Also as per usual, Firestorm 6.5.3 includes additional fixes and updates directly from the Firestorm team to also improve the user experience. Not all of these are covered in the notes below, and readers are referred to the official release notes alongside of this article.

Table of Contents


  • There is no need to perform a clean install with this release if you do not wish to.
  • Do, however, make sure you back-up all your settings safely so you can restore them after installing 6.5.3.

Splash Screen Update

Whilst not strictly part of the 6.5.3 release, having been prototyped with and added to the 6.4.21 release, Firestorm now has a new splash / log-in screen. It incorporates elements familiar to Firestorm users and also to users of viewers that use splash screens more closely modelled on Lab’s own.

In all, the “new” Splash screen can be split into five elements:

  • A set of six panels at the top, four of which are Firestorm-specific (version details, wiki and  Jira links, and on the far right, Firestorm social media links), and two related to official SL information (grid status data and links to information on current grid issues, LL support and grid status updates).
  • A three-panel selection of blog links from the Firestorm blog, the official SL Featured News blog and the SL Blogger’s Network.
  • An expandable scrollable list of currently-popular destinations in Second Life (complete with a count of recent visitors).
    • These are drawn from the What’s Hot Now (default), Recently Added, Featured Events and Editors Picks sections of the Destination Guide (the corresponding links on the right of the panel to select these).
    • Clicking on any of the displayed thumbnails will provide further information on the destination in a pop-up floater, complete with the option to Visit This Destination after logging-in.
  • The Firestorm & associated software logos.
  • The log-in panel at the bottom (unchanged, and not shown below).

Linden Lab Viewer Parity

This release brings Firestorm up to parity with the official viewer release 6.5.2, and so includes updates seen in the following official viewer releases:

  • Mac Voice hotfix viewer, version, dated January 13th, 2022.
  • Cache + 360º Capture viewer, version, dated December 7th, promoted December 15th – see below for more on the 360º capture.
  • Maintenance RC viewer version, dated November 10th, promoted November 15th, 2021.
  • The Apple Notarisation Fix viewer, version, issued September 24th and promoted October 15th, 2021.
  • CEF update viewer, version, dated July 24th, promoted August 10th, 2021.
  • Fernet Maintenance RC, version, dated July 14th, promoted July 19th,  2021.

More Robust Encryption of Login Credentials

In line with changes from Linden Lab, the way Firestorm encrypts your log-in credentials has been changed  to make it more robust and to reduce the number of times stored passwords will have to be re-entered. The update to the new method is automatic on logging-in to SL for the first time using Firestorm 6.5.3; however, it means that should you switch back to using an older version of Firestorm, you will have to re-enter your credentials.

Note: this update is not in any way related to multi-factor authentication in the viewer, which is currently in RC testing in the official viewer.

360º Snapshots

Linden Lab’s 360º snapshot capability allows you to capture of 360º degree panoramic images of environment around your avatar / camera position (if freecamming). The images are automatically processed by the viewer so that they can be uploaded to most platforms supporting 360º panoramic images (e.g. Flickr, Meta), and for embedding into blogs that support 360º images (such as WordPress).

Within Firestorm, the capability can be accessed in one of three ways (Firestorm have disabled the shortcut option of CTRL-ALT-SHIFT-S, as this combination is bound to opening the viewer’s Debug settings):

  • Via Avatar → 360 Snapshot.
  • By clicking on the links seen in the expanded Preview image view of the Snapshot floater.
  • Via a toolbar button (when enabled in a toolbar area).
The 360º snapshot viewer and two of the means of accessing in – via the the Avatar menu and the toolbar button (must be added to your toolbar)

Taking an image comprises a few simple steps:

  1. Position your camera.
  2. Select the image quality – for finished images you’ll need to set High or Maximum quality using the radio buttons.
  3. Click the Create 360º Image button to generate a preview in the floater’s preview panel.
  4. Click on the preview image and drag it around to ensure what you’re seeing is what you want / that things like textures have actually rendered correctly.
  5. Check the Hide All Avatars option, if required – if not, the process to include all avatars present, which could be blurred if they are moving at the time the image elements are  captured.
  6. When you are satisfied with the preview, click Save As… to save it to your hard drive, renaming it if / as required.

Note: if you change the image quality, you must also click Create 360 button to update the preview AND image capture process to the new image quality, before clicking Save As… once more.

Further information on the capability can be found in the following blog posts :

Improve Graphics Speed (Experimental)

Overview (please read!)

This is a new UI floater Developed by Beq Janus. It brings together a range of viewer graphics options and is intended to help keep you better informed of the viewer’s performance in terms of frame rates, rendering, etc.), and make your own adjustments to suit the environment you’re in. It is also intended to help users be better informed about viewer performance.

The floater comprises three core elements:

  • The Frame / Performance Summary.
  • An Auto Tune Capability.
  • Four additional floater panels that can be used together / individually and independently of Auto Tune. These bring together some of the most commonly-user graphics / rendering options, allowing you to make changes quickly and easily to manually adjust performance, including defining how avatars around you are individually rendered, and lowering to load your own avatar places on both your system and those of the people around you.

This section is intended to provide an overview to the new floater, and offer general notes on the various options and their use. When reading it, please remember:

  • The entire panel – and particularly the Auto Tune capability – is experimental. Options presented may well change over time (such as in reference to LL’s own performance improvement work).
  • While intended to try to optimise the viewer’s performance, please note: these options  will not magically make elderly (e.g. 6+ year old) computers with outdated CPUs / GPUs suddenly zoom along at rates seen with the latest high-end gaming rigs; everything is very much dependent on the capabilities of your hardware.
  • Also, and in respect of Auto Tune:
    • While it will try to maintain your frame rate at the expense of other settings (such as overall graphics quality). So, depending on your system, the frame rate selected, the complexity of the scene, you may find other aspects of your experience suffering.
    • Does not run on Mac M1 systems at present.
  • If you experience particularly awkward results or are unhappy with how the in-world scene looks, you can disable all performance optimisation, and the floater includes the means to quickly load / revert to any Graphics Presets you have previously set-up.

Accessing the Floater

The Improve Graphics Speed floater can be accessed in two ways:

  • Via World → Improve Graphics Speed.
  • Via a toolbar button (when enabled in a toolbar area).

The various options and panel displays are examined in the sections below.

Firestorm 6.4.21: catching up with the Lab

On Wednesday, July 28th, 2021, the Firestorm team released version 6.4.21 of their viewer.

The majority of the updates contained within this release are from recent releases of the official viewer, with a minimal number of Firestorm-derived updates, as Firestorm continues to move closer to a quarterly cadence of releases.

That said, as well as fixes and updates, this release includes a number of additional and new capabilities added by the Firestorm team, and these form the focus of this overview.

As is usual for me, this is not a review of every individual change to be found within this latest release of Firestorm. Rather, it is an overview of those changes that will be most noticeable to the majority of users. Given this, please refer to the official release notes for a complete list of fixes and changes.

Table of Contents


  • There is no need to perform a clean install with this release if you do not wish to.
  • Do, however, make sure you back-up all your settings safely so you can restore them after installing 6.4.21.
  • Again, please refer to the Firestorm 6.4.21 release notes for additional details of all changes and updates in this release.

Linden Lab Viewer Parity

Firestorm 6.4.21 incorporates updates from a number of recent Linden Lab viewer releases, as follows:

Jelly Updates, February 2021

Viewer release:

Most notably, this alters the behaviour of “jellydolled” avatars for better performance. Those avatars explicitly set not to render or have an Avatar Rendering Complexity (ARC) that exceeds the threshold set within the viewer (e.g. via Quick Prefs → Max Complexity slider):

  • Are now rendered a single grey, rather than appearing in a range of solid colours and as a basic humanoid shape.
  • No longer have any attachments or other customisations rendered and do not play animations.

Simplified Cache Viewer, March 2021

Viewer release:

This viewer introduced a less complex file caching system to save local copies of frequently used assets such as meshes, sounds and animations, but without the issues that impacted the original deployment of that viewer.

Custom Key Mappings Viewer, April 2021

Viewer release:

This release allows users to define their own key mappings for a number of viewer functions, via Preferences → Control .

The Custom Key Mappings panel in Preferences

Maintenance Eau de Vie, April 2021

Viewer release:

A further round of viewer bug fixes from Linden Lab. Perhaps most notable among them changes to the detection of Intel HD 2500 and 4000 and 400 GPUs (if running the latest drivers), that result in users of those graphics cards now being offered the 64bit version of the viewer.

Love Me Render 5, June 2021

Viewer release:

A maintenance viewer focused on rendering and graphics fixes, including a number of EEP improvements.

UI and Voice Updates Viewer, June 2021

New Guidebook

Viewer release:

This viewer introduced the first in a series of viewer UI updates, these specifically aimed at new users, notably a new Guidebook to getting started in Second Life following sign-up, and which is intended to be used within the new Welcome Islands.

The new user Guidebook, as developed by Linden Lab as a part of a new user experience
The Guidebook is access via a dedicated Toolbar Button, which if not automatically displayed in your viewer (clean installation) can be accessed by opening the Toolbar Buttons panel (right-click any button area and select Toolbar Buttons …) and then dragging the Guidebook button to your preferred button area.

Not that both the Guidebook and the new Welcome islands are subject to on-going testing and so may see further revisions.

Menu Updates

In addition, this release of the view included a number of menu changes to the official viewer. These have been implemented somewhat differently in Firestorm, and so are dealt with below.

EEP: Azimuth and Elevation Sliders

A further UI change with this viewer is the addition of new EEP sliders for those who have issues using the Trackballs in the Sun / Moon tabs of the Fixed Sky and Day Cycle floaters, and in the Personal Lighting floater. These sliders are:

  • Azimuth – which might be thought of as the east / west position of the Sun or Moon (technically, azimuth is more than this, but it’ll do for these notes).
  • Elevation – the position of the Sun or Moon over or under) the horizon, relative to azimuth.

They are tied to the Sun / Moon movement, so when used, the trackball locations for the Sun and Moon will also move.

Voice Updates

Finally, this viewer brings a series of improvements to the viewer’s Voice settings a range of improvements to Voice handling, including changing to default Voice settings in the viewer intended to help prevent issues of drop-out when talking, and which have reportedly all but eliminated drop-outs for those using the new settings. Additionally, the VIVOX VAD options have been exposed via Debug Settings, and detailed notes on these can be found in the official viewer release notes, linked to above.

Firestorm 6.4.13 release

On Monday March 15th, 2021, the Firestorm team released version 6.4.13 of their viewer.

Regarded somewhat as a maintenance update more than a major release, the primary am of 6.4.13 is to hopefully move Firestorm into its quarterly cadence of releases.

That said, as well as fixes and updates, this release includes a number of additional and new capabilities added by the Firestorm team, and these form the focus of this overview.


  • There is no need to perform a clean install with this release if you do not wish to.
Table of Contents


  • Do, however, make sure you back-up all your settings safely so you can restore them after installing 6.4.13.
  • Again, please refer to the Firestorm 6.4.13 release notes for additional details of all changes and updates in this release.

Linden Lab Derived Updates

This release brings Firestorm up to parity with the Lab’s Dawa Maintenance RC, which focused on bug fixes. This viewer became the Lab’s default viewer on February 1st, 2021.

Menu Updates

Avatar Menu: Recreate  LSL Bridge

If you encounter issues with the Firestorm Bridge, you can now recreate it via Avatar → Avatar Health → Recreate LSL Bridge.

Note: you must be on a script-enabled region / parcel for this to work.

World Menu: Bulk Windlight Import to EEP

With Firestorm 6.4.13, it is now possible to bulk import Windlight .XML files directly to inventory as EEP settings / assets.

  • Go to World → Environment → Bulk Import
  • Select the EEP type you’d like to use for the import process (days, skies, water).
  • A file selection window will open. Use this to navigate to the folder on your computer containing the corresponding Windlight .XML files.
  • Use SHIFT-left-click / CTRL-left-click to  highlight the .XML files you wish to import and click Open at the bottom of the window.
  • The window will close and the import process will import the .XML files and convert them to corresponding EEP settings and assets using the original Windlight file name, placing them in the Settings folder in your inventory.
Bulk import of Windlight .XML file to EEP settings / assets

Side notes:

  • You must ensure you select the correct import type / .XML fly type for this to work. For example: if you click on Skies, you must import .XML static sky files. Selecting the wrong import option or the wrong file type will result in a file validation error.
  • Remember that the viewer already includes around 200 of the more popular Windlight .XML files already converted to EEP settings .
    • These can be found in the Library Environments folder, and can be copied to your Settings folder (or a folder of your choice) in inventory and used from there.
    • It  may be easier to check this folder for the more popular Windlights, as you may find those you have on your computer.

World Menu: Asset Blacklist Sound Button

The Asset Blacklist floater now includes a Play Sound button. When a sound item you’re added to the list is highlighted, the button will be enabled and can be used to hear the sound in question.

Build Menu: Mesh Uploader

The Mesh Uploader now includes a new tab: Preview Settings.

Mesh Uploader Preview Settings

Preferences Updates

Move & View: Avatar Rotation Speed

  • Movement → Avatar Rotation Turn Speed slider: alters the rate at which your avatar responds to turning. 0-100 as estimated percentage of the maximum turn rate. Note that high values will be snappy/jerky.

User Interface: Use Small Camera Window

With the introduction of Camera Presets, the standard camera floater was revised to include buttons for setting and using the Presets capability. However, some have found this revised floater intrusive.

When checked, Preferences → User Interface → Interface Windows → Use Small Camera Window will replace the revised camera floater with the “old” pre-Camera Preset camera floater. Unchecking the option will display the revised window floater once more.

Using the “old” camera floater


  • The revised camera floater can be resized to something approaching that of the “old” floater, for those who would like to retain the new floater but wish to reduce the amount of screen space it takes up.
  • If, for any reason, you revert to an earlier version of Firestorm (while available) with this option enabled, the next time you use Firestorm 6.4.13, you will have both versions of the camera floater displayed. Toggle the setting to correct.

User Interface: Time Format

  • Preferences → User Interface → Top Bars → Time Format: a drop-down allowing you to set the preferred time format (12 hour or 24 hour notation, etc.), as displayed in the top right corner for the viewer.
Time format options
