Firestorm 6.6.8: Profiles, Local Mesh and more

Posted on by Inara Pey
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 .

 Table of Contents

 

For a complete breakdown of changes, please see the official release notes for Firestorm 6.6.8.

Installation

  • 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 6.6.8.68380 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 6.6.7.576223, 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 6.6.4.575022, September 2022 – correcting a crasher within the viewer code.

Maintenance Nomayo Viewer Updates

Viewer version 6.6.5.575749, 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-232466, FIRE-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 6.6.6.575990, October 2022.

  • Fix for a transparency “alpha” blending issues in the above viewer release. In cases of many layers of textures that included transparencies, this would cause some of the lower layers to not render at all.

Maintenance Izzara Viewer Updates

Viewer version 6.6.4.574885, 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 6.6.3.574158 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 my.secondlife.com).

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 my.secondlife.com).
  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.

2023 SL Puppetry project week #2 summary

Posted on by Inara Pey
Puppetry demonstration via Linden Lab – see below.  Demos video with the LL comment “We have some basic things working with a webcam and Second Life but there’s more to do before it’s as animated as we want.”

The following notes have been taken from chat logs and audio recording of the Thursday, January 12th, 2023 Puppetry Project meetings held at the Castelet Puppetry Theatre on Aditi. These meetings are generally held on alternate weeks to the Content Creation User Group (CCUG), on same day / time (Thursdays at 13:00 SLT).

Notes in these summaries are not intended to be a full transcript of every meeting, but to highlight project progress / major topics of discussion.

Project Summary

General description of the project and its inception:

LL’s renewed interest in puppetry was primarily instigated by Philip joining LL as official advisor, and so it really was about streaming mocap. That is what Philip was interested in and why we started looking at it again. However since Puppetry’s announcement what I’ve been hearing from many SL Residents is: what they really want from “puppetry” is more physicality of the avatar in-world: picking up objects, holding hands, higher fidelity collisions. 
As a result, that is what I’ve been contemplating: how to improve the control and physicality of the the avatar. Can that be the new improved direction of the Puppetry project? How to do it?

Leviathan Linden

  • Previously referred to as “avatar expressiveness”, Puppetry is intended to provide a means by which avatars can mimic physical world actions by their owners (e.g. head, hand, arm movements) through tools such as a webcam and using technologies like inverse kinematics (IK) and the  LLSD Event API Plug-in (LEAP) system.
    • Note that facial expressions and finger movements are not currently enabled.
    • Most movement is in the 2D plain (e.g., hand movements from side-to-side but not forward / back), due to limitations with things like depth of field tracking through a webcam, which has yet to be addressed.
  • The back-end support for the capability is only available on Aditi (the Beta grid) and within the following regions: Bunraku, Marionette, and Castelet.
  • Puppetry requires the use of a dedicated viewer, the Project Puppetry viewer, available through the official Second Life Alternate Viewers page.
  • No other special needs beyond the project viewer are required to “see” Puppetry animations. However, to use the capability to animate your own avatar and broadcast the results, requires additional work – refer to the links below.
  • This project is taking in a lot of additional ideas – animation standards, improving the current animation system, enabling truer avatar / avatar and avatar object interactions such that it is likely to evolve into a rolling development, with immediate targets for development / implementation as they are agreed upon, to be followed by future enhancements.
  • As such, much of what goes into the meetings at present is general discussion and recommendations for consideration, rather than confirmed lines o development.
  • There is a Puppetry Discord channel – those wishing to join it should contact members of LL’s puppetry team, e.g. Aura Linden, Simon Linden, Rider Linden, Leviathan Linden (not a full list of names at this time – my apologies to those involved whom I have missed).

Bugs, Feature Requests and Code Submissions

  • For those experimenting with Puppetry, Jiras (bug reports / fixes or feature requests) should be filed with “[Puppetry]” at the start of the Jira title.
  • There is also a public facing Kanban board with public issues – those experiencing issues can also contact Wulf Linden.
  • Those wishing to submit code (plug-ins or other) or who wish to offer a specific feature that might be used with Puppetry should:

Meeting Notes

LSL Integration

  • See: OPEN-375: “LSL Functions for reading avatar animation positions”.
  • Rider Linden is starting to look at LSL integration  – the first step being to make the simulator aware of what is actually animating.
  • Currently, the code he has developed lets the server know the position of an avatars attachment points; this sends details of 55 points (HUD points excepted). Attachment points have been selected over bones, as the simulator already has a solid concept of attachment points, and it avoids complications with rigged meshes “doing their own thing” with bone positions.
  • A concern with this is the number of updates being sent to the server for processing.
    • One idea is to refine the the code so that only the attachment points which change relative to the avatar centre (avatar frame/Local Position relative to the avatar) actually send information to the server, in order to reduce the number of updates being generated.
    • Another idea might be to only send updates every n frames, rather than every frame. This would reduce the fidelity of movement, but could still provide sufficient data while reducing the load on the simulator, particularly where multiple avatars in a region are using puppetry.
  • This issue is related to synchronising puppetry actions across multiple viewers as well; a long-standing issues, given that animation playback of animations is viewer-side, and not genuinely across viewers (the resync function found in some TPVs only does so locally).
  • All of the above lead to a discussions of ways and means to best allow LSL integration with animations and ensure a reasonable transmission of results together with decent synchronisation between the viewer and the simulator, whether by frame count or time stamp, in order to ensure predictability of results across multiple viewers. .
  • In addition, the discussion included the advantage in enhancing Second Life to support procedural animations as well as the current canned animations.
  • Rider is also looking into a script enhancement to register collisions.
  • There was some conflating of ideas during the discussion – immediate first steps in opening Puppetry to LSL, and more far reaching goals – setting position, registering collisions (per the above), defining better interpolation for positioning (e.g. as defined in the Khronos glTF specification), etc., which caused a degree of confusion.
  • However, the openness towards making Puppetry a good foundation for future enhancement (such as moving more to procedural-based animations, enabling SL to support “industry standard” animation workflows to encourage animators into the platform, etc., remains, together with (hopefully) enabling more realistic avatar / avatar and avatar / object interactions.
  • That said, Simon Linden did offer a not of caution to all discussing the work:
Not to pop the bubble, but every one please keep in mind all the stuff we’re talked about is experimental and really interesting. I have no idea what we can make into real features and what can work with crowds and all the other interesting problems to make it happen well – we’ll see what we all can do this year 🙂

– Simon Linden

2023 SL SUG meetings week #2 summary

Posted on by Inara Pey
Le’eaf and Tinsel Café, Heterocera – blog post

The following notes were taken from the Tuesday, January 10th, 2023 Simulator User Group (SUG) meeting. They form a summary of the items discussed and is not intended to be a full transcript. A video of the entire meeting is embedded at the end of the article for those wishing to review the meeting in full – my thanks to Pantera for recording it.

Server Deployments

  • On Tuesday, January 10th 2023, the simhosts on the Main SLS channel were restarted with no deployment, leaving them on simulator version 576542.
  • On Wednesday, January 11th, 2023, the simhosts on the RC channels should see the deployment of the ability to to play 30-second sound clips and the new sound functions llLinkPlaySound, with llLinkStopSound llLinkAdjustSoundVolume and llLinkSoundRange which allow sounds in child prims of a linkset to be played without the need for a supporting script.

It is hoped that week #3 will see a deployment of an RC simulator update comprising custom HTTP headers (total space for headers will increase to 4k and the limit on the number of headers will be dropped), and new cryptographic signing utilities – potentially llHMAC (per BUG-233005) and llSignRSA and llVerifyRSA (per BUG-233009). These updates will be available for testing on the Juggly Puff region within Aditi (the beta grid) during the rest of week #2.

Available Official Viewers

This list reflects the current status of available official viewers at the start of 2023:

  • Release viewer: Maintenance P (Preferences, Position and Paste) RC viewer version 6.6.8.576863 Monday, December 12, 2022 – No change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • Maintenance (Q)uality RC viewer, version 6.6.9.577418, January 4, 2023.
    • Performance Floater / Auto-FPS RC viewer, version 6.6.9.577251, January 4, 2023.
  • Project viewers:
    • PBR Materials project viewer, version 7.0.0.577157, December 14, 2022.
      • This viewer will only function on the following Aditi (beta grid) regions: Materials1; Materials Adult and Rumpus Room 1 through 4.
    • Puppetry project viewer, version 6.6.8.576972, December 8, 2022.

In Brief

  • An update to Linkset Data to fix the sorting for LSDFindKeys is being targeted for a maintenance release in early February. Further LSD updates and fixes are being considered, but Rinder Linden would like to get this update out ASAP, rather than waiting to bundle it with other LSD updates.
  • BUG-232037 “Avatar Online / Offline Status Not Correctly Updating” – LL may have a fix available by earlier March.
  • BUG-233107 “Objects failing to render is happening more frequently of late” – is still believed to be an Interest List issue, although that code has not been directly touched in a while. One theory is the server is unsubscribing users from certain objects for reasons unknown (and which would impact entire linksets were the root to be unsubscribed). However, further investigation is required.
    • This issue leads to an extended discussion on passible causes and on the Interest List in general – please refer to the video below.

2023 week #1: SL CCUG meeting summary

Posted on by Inara Pey
Mullein Woods, November 2022 – blog post
The following notes were taken from m y audio recording and chat log transcript of the Content Creation User Group (CCUG) meeting held on Thursday, January 5th 2023 at 13:00 SLT. These meetings are chaired by Vir Linden, and their dates and times can be obtained from the SL Public Calendar; also note that the following is a summary of the key topics discussed in the meeting and is not intended to be a full transcript of all points raised.

Official Viewers Status

  • On Wednesday, January 4th, 2023:
    • The Maintenance Q(uality) RC viewer updated to version 6.6.9.577418.
    • The Performance Floater / Auto-FPS RC viewer updated to version 6.6.9.577251.
  • Both the VS 2022 Build RC viewer and the LMR6 project viewer have been withdrawn.
This leaves the rest of the currently-available official viewer as:
  • Release viewer: Maintenance P (Preferences, Position and Paste) RC viewer version 6.6.8.576863 Monday, December 12, 2022.
  • Project viewers:
    • PBR Materials project viewer, version 7.0.0.577157, December 14, 2022. Note: this viewer will only function on the following Aditi (beta grid) regions: Materials1; Materials Adult and Rumpus Room 1 through 4.
    • Puppetry project viewer, version 6.6.8.576972, December 8, 2022.

Inventory Enhancement Project

Linden Lab is looking to enhance the Inventory system.
  • The first element of this work is to be the addition of a fixed-resolution thumbnail preview capability, allowing users to see a small image of a given object (where this makes sense – so the likes of note cards and scripts would be excluded) within inventory, with these thumbnails either being of individual items or entire folders.
    • The first phase of the work is determining how to generate the thumbnail images and ensure they maintain an association with the objects to which they are related (e.g. so if an item is sold or transferred to another user, the thumbnail goes with it).
    • Once this has been decided, the next phase will be to build-out the UI so that such thumbnails can be viewed from inventory.
    • This work will not replace the Outfit Folder image capability nor will it prevent creators from including high resolution images with their products if they wish.
  • Once the thumbnail preview work has been completed, it is possible the Lab will look to further enhancements to inventory management. One future enhancement under consideration is support for folders to be included in the Contents inventory of individual objects.

glTF Materials and Reflection Probes

Project Summary

  • To provide support for PBR materials using the core glTF 2.0 specification Section 3.9 and using mikkTSpace tangents, including the ability to have PBR Materials assets which can be applied to surfaces and also traded / sold.
  • To provide support for reflection probes and cubemap reflections.
  • The overall goal is to provide as much support for the glTF 2.0 specification as possible.
  • The project viewer is available via the Alternate Viewers page, but will only work on the following regions on Aditi (the Beta grid):  Materials1; Materials Adult and Rumpus Room 1 through 4.
  • Please also see previous CCUG meeting summaries for further background on this project.

Status

  • The focus remains on bug and regression issue fixing within the viewer and quality of life improvements, particularly as in wider grid testing, it has been found the PBR viewer can only generate single-digit FPS in some regions.
  • Screen Space Reflections (SSR): Geenz Linden continues to work on integrating SSR into the PBR viewer, but is encountering issues.

Animation System Enhancements – A Discussion

In response to requests for the animation system to be improved (e.g. via CCUG meetings, as a result of the Puppetry project, etc.), Vir Linden asked those at the meeting to state what they see as the most important changes / updates they would like to see. Responses included those expressed at the Server User Group meeting earlier in the week:
  • A procedural animation system to allow creators / users to set the rules of how avatars walk, run, jump; their timings, how animations play priority wise and mixing wise in the series, all able to be packaged up into an item – it has been suggested that whilst “old” the SL is well-placed to be folded into a procedural animation system.

  • Improved animation formats and easier means of animation import into Second Life.
  • The ability to dynamically set animation priorities for more fluid animation integration (e.g. when you are holding and pointing a gun, you continue to point it as you walk, rather than the avatar’s arm dropping to a walking animation when moving).
  • Viewer-side animation editor.
  • Better support for inverse kinematics.
  • Collaboration between the Puppetry team, the glTF team and any animation project to ensure consistency of decision-making about formats, proper LSL support / calls, etc.
This discussion covered a lot of ground, including the potential for the implementation of an “animation 2.0” system which could potentially operate alongside the existing system (much like PBR materials and “legacy” materials); the benefits in greater adherence to emerging standards – particularly in the area of avatar / skeleton formats and capabilities, and the fact that SL is both well-placed to be a part of defining those standards whilst also being hamper by the fact the existing SL avatar format is a niche product / approach, and more. However, the two key points of the discussion might be summarised as:
  • Changes to the animation  / avatar systems are not projects the Lab is working on at present.
  • However, the it demonstrates that, as with recent projects, the Lab is looking seriously at enhancing SL and moving it towards more readily understood standards. As such, it is taking the time to ascertain options that are exciting to creators an users and which might be seen s benefiting the platform and its future growth, and so might be formalised into active projects – and include user engagement where appropriate in their development.
In terms of what might be attempted by way of “small-scale” improvements to the animation system, the viewpoint from LL is that the ability to dynamically set animation priorities and adding scaling support to the animation format are seen as providing users / creators with recognisable benefits.

Next Meeting
