2024 SL SUG meetings week #11 summary

Posted on by Inara Pey
Soulstone, February 2024 – blog post †

The following notes were taken from the Tuesday, March 12th, 2024 Simulator User Group (SUG) meeting. They form a summary of the items discussed, and are not intended to be a full transcript, and were taken from a chat log (thank you, Yuzuru!) and the video embedded below, recorded by Pantera – my thanks as always for her work.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Simulator Deployments

Upcoming Simulator Release

  • The next RC update (scheduled for week #12) is Hearts & Flowers, which will go to the BlueSteel RC channel. This mostly comprises internal (non-user visible) updates, together with these user-visible additions:
    • llSetLinkSitFlags/llGetLinkSitFlags – allow you to adjust the sit flags for a prim. It supports the existing two SIT_FLAG_ALLOW_UNSIT and SCRIPT_ONLY.
      • At some future point, SIT_FLAG_HIDE_AVATAR should also be added, so you don’t need to play an animation that squishes the avatar so they aren’t visible in something like a very small vehicle.
    • A feature for estate managers that will allow them to schedule automatic region restarts (see below).
    • A new constant in llSPP PRIM_SIT_FLAGS it will contain all the sit flag information, (including ALLOW_UNSIT and SCRIPTED_ONLY (the two older constants will still be available).
    • A new capability to load item inventory lists via HTTP (so items with large contents will load faster when accessed, although this will require a viewer update as well).
    • A fix for avatars going into an animation thrash between falling and flying when using llSetHoverHeight() from an attachment.
  • The next update after that will likely be called Spring Break. This might include notecard searches.

Schedule Region Restarts

Once fully deployed as a part of the Heart & Flowers simulator update (see above) this:

  • Will allow region and estate owners / managers schedule region restarts via the region console in the viewer (when updated).
  • Allows schedules to be set on a Daily or Weekly basis (e.g. every day at 06:00 SLT; Monday & Thursday at 17:00, etc.)
  • Has “vaccination” period of +/- 5 minutes of the selected restart time, so that all regions in an estate don’t suddenly restart at exactly the same time.
  • Allows any scheduled restart to be cancelled in the same manner as existing manual restarts.

Viewer Updates

On Monday March 11th:

  • The glTF PBR Materials Maintenance-2 RC viewer updated to version 7.1.4.8149792635.
  • The Maintenance X RC (usability improvements) updated to version 7.1.4.8148263040.

The rest of the current official viewers in the pipe remain as:

  • Release viewer: version 7.1.3.7878383867, the Emoji Viewer, issued February 15, promoted March 1st, 2024 – No Change.
  • Release channel cohorts:
    • Maintenance-W RC (bug and crash fixes) updated to version 7.1.4.8113624779, on March 6th, 2024.
    • Maintenance Y RC ( My Outfits folder improvements; ability to remove entries from landmark history + Maint Z RC integration) updated to version 7.1.4.8114240508, March 6, 2024.
  • Project viewers:
    • No updates.

Game Controller Update

  • No news from Leviathan Linden – he’s been busy on other tasks.
  • Rider has included the simulator support Leviathan has written into his Combat regions on Aditi (regions Gallipoli and Thermopylae) so those engaged in the Rooty Tooty Shooty Society (RTSS) testing his updates to the SLCS (Second Life Combat System) can try things out.

Simulator Main Loop Breakdown

  • Monty Linden has published details of the simulator main loop (where time deltas occur and state changes and housekeeping tasks are organised), as a high-level breakdown of the loop and a description that relates simulation back to the viewer’s Statistics floater.

In Brief

  • In the previous SUG meeting, there was a request to help solve the problem of cheaters sitting on competition vehicles. Someone sits on the object and uses a HUD with llSetVelocity() or other calls to push the vehicle faster than it would normally go. As there have been wider requests for such a fix for dynamic non-vehicle objects, he sought feedback on other situations wherein objects are messed with by “pusher HUDs”.
  • A discussion on scripting hover height changes which also segued into a discussion on swimming within Linden Water and improving the user experience (particularly for new users, who mix expect to start swimming in water, rather than sinking to the sea floor and walking, before morphing into a discussion on Pathfinding and its limitation. This continued through the meeting from around 12:11 SLT through to about the end of the meeting.
  • As animations were mentioned, Brad Linden noted that there are features in the GLTF spec for rigged meshes and animations that LL wants to support, and will want to provide some “best effort” interoperability of those assets with existing skeletons and animations (e.g. animation retargeting, individual bone scaling). However, all of the details and schedule for this work are currently TBD.

2024 week #10: SL CCUG summary

Posted on by Inara Pey
Monkey Island, February 2024 – blog post †

The following notes were taken from my audio recording and chat log transcript of the Content Creation User Group (CCUG) meeting held on Thursday, March 7th, 2024.

My apologies for the lateness of this report appearing; right now I have a lot going on in the physical world, and the blog and SL are having to take a back seat through until early April, after which things should start to (hopefully) return to normal.

Meeting Purpose

  • The CCUG meeting is for discussion of work related to content creation in Second Life, including current and upcoming LL projects, and encompasses requests or comments from the community, together with related viewer development work. This meeting is held on alternate Thursdays at Hippotropolis.
  • In regards to meetings:
    • Dates and times are recorded in the SL Public Calendar.
    • Commence at 13:00 SLT on their respective dates.
    • Are conducted in a mix of Voice and text chat.
    • Are open to all with an interest in content creation.
  • The notes herein are a summary of topics discussed and are not intended to be a full transcript of the meeting.

Official Viewers Status

  • The Maintenance-W RC (bug and crash fixes) updated to version 7.1.4.8113624779, on March 6th, 2024.
  • The Maintenance Y RC ( My Outfits folder improvements; ability to remove entries from landmark history + Maint Z RC integration) updated to version 7.1.4.8114240508, March 6, 2024.

Both of the above are at parity with the Emoji release viewer. The rest of the current crop of official viewers remains:

  • Release viewer: version 7.1.3.7878383867, the Emoji Viewer, issued February 15, promoted March 1st, 2024 – NEW.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • glTF PBR Materials Maintenance-2 RC viewer, version 7.1.3.7821226606, February 20, 2024.
    • Maintenance X RC (usability improvements), version 7.1.3.7721015131 , February 14, 2024.
  • Project viewers:

Graphics / glTF

  • Work continues on the GLTF Featurettes viewer, and it is hoped the release on an official project viewer is now not far off. This viewer includes:
    • Geenz Linden’s work on Mirrors, including his latest updates to the capability.
    • Cosmic Linden’s work on applying glTF materials to terrain (currently going through UI bug fixing + this is going to possibly reduce the number of texture repeats in light of 2K textures).
    • Updates which will allow the glTF / PBR swatch boxes in the Build / Edit floater display previews of the materials being selected, rather than grey boxes.
    • The first series of additional glTF extensions – Index of Refraction.
    • Initial work on 2K textures support.
    • Local high dynamic range imaging (HDRI) preview. This will allow content creators to view content in-world under the same HRDI settings as they are using in their tool of choice as a sanity check as SL environments / EEP will render them differently, leading to potential confusion and a belief that the HDRI settings are “wrong”.
    • The nightly builds version of the Featurette viewer is available on Github, but is not suitable for use as a primary viewer, and the capabilities are not supported on the Main grid. As such, this viewer should only be used by those wishing to test the capabilities.
    • The Rumpus Room 2048 region (and neighbours) on Aditi provides back-end support for the Featurettes viewer.
  • With reference to 2K textures, it was noted that while the viewer will have the ability to upload them, the actual ability to do so will be under the control of the simulator code; so just having the viewer-side update does not necessarily mean 2K textures can be uploaded grid-wide.
  • glTF terrain texturing: the focus has been on bug fixing and improving usability.

In Brief

  • Materials support for Bakes on Mesh: this has frequently been requested, and while it has a placeholder in the the Lab’s plans for possible implementation, it is is not currently scheduled to be worked on.
  • It was reiterated that blend shapes will be part of the work to support glTF scene import.
    • glTF scene import will allow and entire glTF scene file (scripts, node hierarchy, etc.) to be imported to SL and essentially “hung off” of a single object in-world.
    • Exactly how this will work, what limitations it will have, etc., in order to avoid “breaking” SL or opening griefing vectors, etc., has yet to be decided.
    • Similarly, glTF scene support will have its own Land Impact calculations, which are currently still TBD within the Lab.
    • Currently, glTF is due to start-up as a major project after the glTF featurette viewer has reached release status.
  • Splat Maps have been requested in the past with terrain painting. These are described as “in the early phase of consideration”, and if taken on, might be a “PBR Terrain Phase II” feature.
  • The subject of separating head and body shapes was raised – this has been the subject of a feature request, which has been accepted (Tracked). As always, “accepted” does not necessarily equate to it being quickly implemented.
  • Land Impact:
    • An update to the Land Impact is due to be deployed on the simulator side, in the Hearts and Flowers release (due to start deployment on March 13th, 2024).
    • This does not change the total Land Capacity (“prims”) for a region; but it does reduce the download weight calculated for meshes
    • This equates to a “15% discount” on mesh object Land Impact (all mesh with the exception of Animesh, not just mesh items downloaded after the update is deployed).
  • Reference was made to the upcoming shift of object inventory messaging moving to HTTP.
    • This should result in the contents of objects rezzed in-world loading “many time faster” than is currently the case.
    • The update will be deployed to the simulator code first, and then be subject to a viewer-side update.
  • With the switch to Github / Canny, LL is trying to be more transparent in terms of planning, projects, issues, etc., looking to have as much public as possible (except things like security issues, which need to be limited in who can view them for obvious reasons). However, while this will allow users to see more of what is in the works / being considered, it also means that projects and work can appear to sit apparently dormant for periods even longer than on Jira
  • How (viewer) feature requests are prioritised (in short):
    • Those which are accepted and form small, relatively stand-alone requests will be directed towards “featurette viewers” of the kind like the glTF featurette viewer mentioned above. The hope is that this will allow devs to pick them up and work on theme in between larger projects or when larger projects are stalled for whatever reason, allowing more of this type of request to filter through the the viewer more readily.
      • In addition, if this works and a Canny Board of such requests can be built-up, it might allow LL to open it to open-source developers to pick items they’d like to work on and then contribute the code to LL.
    • Larger-scale feature requests (such as adding materials support to BOM) will be subject to more extensive investigation / evaluation and internal prioritisation against other large-scale / high-value work, by LL.

March 2024 SL Web User Group summary

Posted on by Inara Pey
The Web User Group meeting venue, Denby

The following notes cover the key points from the Web User Group (WUG) meeting, held on Wednesday March 6th, 2024. They form a summary of the items discussed and is not intended to be a full transcript. A video of the meeting, recorded by Pantera Północy, is embedded at the end of this summary – my thanks as always to Pantera for recording it and making it available.

Meeting Overview

  • The Web User Group exists to provide an opportunity for discussion on Second Life web properties and their related functionalities / features. This includes, but is not limited to: the Marketplace, pages surfaced through the secondlife.com dashboard; the available portals (land, support, etc), the forums.
  • As a rule, these meetings are conducted:
    • On the first Wednesday of the month and 14:00 SLT.
    • In both Voice and / or text.
    • At this location.
  • Meetings are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Marketplace

  • The Marketing Team has been working on back end and infrastructure work to upgrade the Marketplace. The updates should be released in the coming days.
  • There were some outages when deploying some updates in the past week, which resulted in issues such as ANS not appearing in Marketplace. This has been corrected, and ANS should be back and working as normal.
  • Once these infrastructure updates are deployed, it clears the way for some new features and UI updates LL has been planning.
    • In terms of UI updates, LL is planning improvements to the viewing products and checking out the Marketplace via the viewer, improving the display size when the floater is changed, and moving the MP so it will display decently on mobile or tablet devices.
    • The feature updates once again have a focus on search. These will include updates based on user feedback / requests, but details of what these will be and the likely time frame for deployment is still being finalised, so details to come. However, “some updates will come faster than others” in terms of information relating to them.

General Discussion / Requests for Marketplace

  • A discussion on making the shopping cart / wish list more flexible.
    • This included requests for more carts for different functions (e.g. a shopping cart specifically for holding items to be purchased as such; carts which could be used to save items for later purchase, separate to the one used for check out, etc.).
    • The latter was particularly popular, either as a cart or a “Save for Later” list (a-la Amazon).
    • Making the wish list function more robust / flexible  / visible (e.g. being able to have more than one wish list).
  • The above spilled into a discussion with the Buy Now button, with some wanting it to include the ability to buy and send gifts directly, rather than having to go through the shopping cart / checkout; some wanting a better distinction between Buy Now and Buy as Gift, as they believe people hit Buy Now mistaking it for Buy as Gift.
  • Both of the above will be looked into.
  • Coupons and vouchers: the ability for merchants to offer coupons and voucher for use on the MP is on the roadmap, but not currently being worked on.
    •  This spilled into the idea of “affiliate” linking – e.g. a person puts together an Flickr image of a look they have created and includes links to the items on the MP – when someone clicks on any of the links and makes a purchase, the originator of the photo gets a referral fee paid to them.
  • There is interest at LL in developing a “You Might Also Like” function / “Also Bought” (again a-la Amazon), wherein items similar to the one being looked at are listed or items other have frequent bought together with the item being looked at are listed (rather than the current merchant-generated “related products” list). But again, not on the current roadmap.

Marketplace Styles

  • Marketplace Styles (allowing things like different colour variants for a product in a single listing) had been given as a capability LL were hoping to deploy before the end of 2022 or early 2023 (see November 2022 Web User Group: new “Plus” subscription level).
  • It is has now been confirmed as something LL has “got designs for” and “would like to get to”. So, as per my January summary comment, if you are a Merchant who has been looking forward to this capability, it is probably best not to hold your breath for its arrival unless you’re especially fond of blue as a facial colour.

In Brief

  • Web Search (viewer):
    • LL are considering a re-working of the current web search page presented in the viewer.
    • The current layout might become “relegated” to being an “advanced search” capability, with tabs being added to the top of the page to make searching easier (e.g. by category – People, Places, Events – rather than having to specifically uncheck or check these on a per search basis.
  • It’s been noted that the use of the word “Resident” when used as part of an account name is inconsistent (e.g. in some searches / actions, only the user’s first name needed to be entered, the “resident” is automatically appended; in others “resident” must be explicitly typed in as a part of the name. LL would like to address this, but no work going forward at present.
  • A discussion on L$1 items, gifting and a “biasing” of top selling item lists., and the idea of limited L$0 items being gifted only to friends of the person using the item as a gift.
  • Further requests to make demo(s) a dedicated category on the MP, or to make a Demo checkbox within listing creation to ensure the metadata indicates an item is a demo, this improving searches wishing to include / exclude demo items without having to rely on keywords.
  • A general conversation on the MP and merchant’s perceptions on how people use the Marketplace.
  • A suggestion to have a Marketplace button in the Profile floater for merchants who have a Marketplace presence – or configurable buttons that people can use to point to their MP store, their Flickr presence, etc. This led to a discussion on Profiles.
  • The WUG meetings are “very close” to becoming biweekly.
  • Note: the video extends beyond the end of the meeting. As this is use chat, rather than specific put to LL, it is not summarised here – please refer to the video.

Next Meeting

  • Wednesday, April 3rd, 2024.

2024 SL SUG meetings week #10 summary

Posted on by Inara Pey
Woodland Café and Library, February 2024 – blog post †

The following notes were taken from the Tuesday, March 5th, 2024 Simulator User Group (SUG) meeting. They form a summary of the items discussed, and are not intended to be a full transcript, and were taken from my chat log and the video embedded below, recorded by Pantera – my thanks as always for her work.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Simulator Deployments

Upcoming Simulator Release

  • The simulator update to follow Gingerbread remains  Hearts & Flowers, which will likely be deployed in the next couple of weeks. This mostly comprises internal (non-user visible) updates, together with these user-visible additions:
    • llSetLinkSitFlags/llGetLinkSitFlags – allow you to adjust the sit flags for a prim. It supports the existing two SIT_FLAG_ALLOW_UNSIT and SCRIPT_ONLY.
      • At some future point, SIT_FLAG_HIDE_AVATAR should also be added, so you don’t need to play an animation that squishes the avatar so they aren’t visible in something like a very small vehicle.
    • A feature for estate managers that will allow them to schedule automatic region restarts (see below).
    • A new constant in llSPP PRIM_SIT_FLAGS it will contain all the sit flag information, (including ALLOW_UNSIT and SCRIPTED_ONLY (the two older constants will still be available).
    • A new capability to load item inventory lists via HTTP (so items with large contents will load faster when accessed, although this will require a viewer update as well).
  • The next update after that will likely be called Spring Break. This might include notecard searches.

Schedule Region Restarts

Once fully deployed as a part of the Heart & Flowers simulator update (see above) this:

  • Will allow region and estate owners / managers schedule region restarts via the region console in the viewer (when updated).
  • Allows schedules to be set on a Daily or Weekly basis (e.g. every day at 06:00 SLT; Monday & Thursday at 17:00, etc.)
  • Has “vaccination” period of +/- 5 minutes of the selected restart time, so that all regions in an estate don’t suddenly restart at exactly the same time.
  • Allows any scheduled restart to be cancelled in the same manner as existing manual restarts.

Viewer Updates

No changes at the start of the week:

  • Release viewer: version 7.1.3.7878383867, the Emoji Viewer, issued February 15, promoted March 1st, 2024.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • Maintenance-W RC (bug and crash fixes), version 7.1.3.7983616888, February 22, 2024.
    • glTF PBR Materials Maintenance-2 RC viewer, version 7.1.3.7821226606, February 20, 2024.
    • Maintenance X RC (usability improvements), version 7.1.3.7721015131 , February 14, 2024.
    • Maintenance Y RC ( My Outfits folder improvements; ability to remove entries from landmark history), version 7.1.3.7790341084, February 9, 2024.
  • Project viewers:

Game Controller Update

  • Leviathan Linden has produced a new GameControl viewer.
  • This has new logic that detects the game controller device and produces the GameControl data, and can be used to drive a Flycam around.
  • The viewer leaves SpaceMouse and other 3Dconnexion devices unchanged, but disables the old game controller logic to drive X-Box style game controllers.

Combat User Group Update

  • It appears that after yours truly wibbled about the Combat committee User Group sharing the same acronym as the Content Creation User Group (CCUG), which could cause confusion, it has apparently been agreed the combat User Group will henceforth be know as the RTSS – the Rooty Tooty Shooty Society – which gets a two thumbs-up from me 😀 .
  • Rider has established two regions on Aditi (the Beta grid) – Gallipoli and Thermopylae (both being appropriate names) – with combat support so people can start getting a feel for the new features as he gets them written, and provide feedback at the meetings (the next being on Thursday, March 14th, 2024).

Region Crossings

  • Monty Linden’s update comprises: “We can now throw avatars into the sea twice as fast as before [so] Developer testing continues 😦 “.

In Brief

  • A request was made for functions that could be used to actively detect forces being applied (e.g. in vehicle racing communities its hard to police cheaters using the push or force functions they have in attachments/HUDs). The request was not to change the force/push functions, but detect their usage by another script.
    • This led to an extended discussion on how best to approach this, options, limitations, etc., running through the meeting for around 20 minutes, from the 20:19 SLT time point to the 20:41 SLT time point.
  • A further discussion of llHealth and Damage from around the 20:41 SLT point through to close to the end of the meeting.

2024 SL SUG meetings week #9 summary

Posted on by Inara Pey
Oblivion, January 2024 – blog post †

The following notes were taken from the Tuesday, February 27th, 2024 Simulator User Group (SUG) meeting. They form a summary of the items discussed, and are not intended to be a full transcript. No video this week, I’m afraid.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Simulator Deployments

  • No SLS Main channel deployment on Tuesday, February 27th, but the simhosts were restarted.
  • Wednesday, February 28th will see the Gingerbread RC update (containing llComputeHash(), llGetCameraAspect(), llGetCameraFOV(), llGetNotecardLineSync() and llWorldPosToHUD() ) re-deployed  to the Bluesteel RC, together with Ferrari and Preflight. It includes a fix for the issue of scripts being prevented from restarting when crossing into regions running on the update.

Upcoming Simulator Release

  • The simulator update to follow Gingerbread remains  Hearts & Flowers, which will likely be deployed in the next couple of weeks. This mostly comprises internal (non-user visible) updates, together with two notably user-visible additions:
    • llSetLinkSitFlags/llGetLinkSitFlags – allow you to adjust the sit flags for a prim. It supports the existing two SIT_FLAG_ALLOW_UNSIT and SCRIPT_ONLY.
    • At some future point, SIT_FLAG_HIDE_AVATAR should also be added, so you don’t need to play an animation that squishes the avatar so they aren’t visible in something like a very small vehicle.
    • A feature for estate managers that will allow them to schedule automatic region restarts.
    • A new constant in llSPP PRIM_SIT_FLAGS it will contain all the sit flag information, (including ALLOW_UNSIT and SCRIPTED_ONLY (the two older constants will still be available).
    • A new capability to load item inventory lists via HTTP (so items with large contents will load faster when accessed, although this will require a viewer update as well).
  • The next update after that will likely be called Spring Break. This might include notecard searches.

Viewer Updates

No changes at the start of the week:

  • Release viewer: version 7.1.2.7215179142, formerly the glTF PBR Materials Maintenance RC, issued December 15, promoted January 8, 2024 – numerous bug fixes and improvements – No Change.
  • Release channel cohorts:
    • Maintenance-W RC (bug and crash fixes), version 7.1.3.7983616888, February 22, 2024.
    • glTF PBR Materials Maintenance-2 RC viewer, version 7.1.3.7821226606, February 20, 2024.
    • Emoji RC viewer, version 7.1.3.7878383867, February 15, 2024.
    • Maintenance X RC (usability improvements), version 7.1.3.7721015131 , February 14, 2024.
    • Maintenance Y RC ( My Outfits folder improvements; ability to remove entries from landmark history), version 7.1.3.7790341084, February 9, 2024.
  • Project viewers:

Game Controller Update

  • Leviathan Linden is still working on trying to get the viewer’s Flycam capability (SpaceNavigator) with the new GameControl logic rather than old system.

Region Crossings

  • Monty Linden is working on the region crossings code (both physical region crossings and all that goes into them when vehicles, etc., are included, and teleports).
  • There has also been independent and on-going investigations by users into crossings. Some of the more recent has been around the issue of the EstablishAgentCommunication (EAC) event between the simulator and viewer (see this forum post for specifics).
  • As it turns out, the server engineering team have been working on an entire simulator to address EAC, which is seen as both problematic and potentially hiding other bugs in the code – and potentially causing issues for the SL Mobile app.

In Brief

  • The Sever Team has a new member – Pepper Linden.
  • There is an upcoming fix to go into a simulator maintenance release for the detach bug stopping all animations started by other attachments or sit objects – see github issue BUG-225288.
  • A further confirmation that the client-side scripting environment will be Luau, a Lua VM implementation developed by Roblox.
    • Note that this project does not encompass delivering client side scripts from inside SL simulator; it is purely viewer-side. Any such capability is seen as being so far down the line as to not be on the roadmap, although the use-cases for such interaction were noted.
  • Rider Linden is looking at llCloseDialog, allowing a script close a dialog that it had previously opened.
  • A general discussion on Experiences – extending the scope of possible controls (not on the immediate roadmap) and making the Join Experience dialogue lees frightening / off-putting to users.

  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Simulator Deployments

  • No SLS Main channel deployment on Tuesday, February 13th, but the simhosts were restarted.
  • Wednesday, February 21st will see the Gingerbread RC update (containing llComputeHash(), llGetCameraAspect(), llGetCameraFOV(), llGetNotecardLineSync() and llWorldPosToHUD() ) rolled-back from the Bluesteel RC channel simhosts.
    • This is due to a bug found over the weekend which prevents scripts restarting when crossing into a region on the Bluesteel channel. It also means the 32 sensors return count (responsible for the issue) will be pulled from Gingerbread, and will be moved to the upcoming Hearts & Flowers simulator update, once Gingerbread has been rolled to the rest of the grid.

Upcoming Simulator Release

The simulator update that will be following Gingerbread will be Hearts & Flowers (probably named for the time of year!). This mostly comprises internal (non-user visible) updates, together with two notably user-visible additions:

  • llSetLinkSitFlags/llGetLinkSitFlags – allow you to adjust the sit flags for a prim. It supports the existing two SIT_FLAG_ALLOW_UNSIT and SCRIPT_ONLY.
    • At some future point, SIT_FLAG_HIDE_AVATAR should also be added, so you don’t need to play an animation that squishes the avatar so they aren’t visible in something like a very small vehicle.
  • A feature for estate managers that will allow them to schedule automatic region restarts.
  • A new constant in llSPP PRIM_SIT_FLAGS it will contain all the sit flag information, (including ALLOW_UNSIT and SCRIPTED_ONLY (the two older constants will still be available).
  • A new capability to load item inventory lists via HTTP (so items with large contents will load faster when accessed, although this will require a viewer update as well).
  • The 32 sensor count capability, mentioned above.

Rider Linden summarised what he plans to achieve in future simulator updates by saying:

I’ll give a Reader’s Digest version. I’ve split up a lot of the work that’s proposed into bite sized pieces and gotten it onto my schedule. (Right after I fix the sensor issue) I’m probably going to start with a couple of pieces of very low hanging fruit. llGetHealth() and fixing the issue where health is not transferred on a region crossing.

Jira End-of-Road

  • All bug reporting/feature request submissions are now transferred to Canny / Github, with the URL for the Second Life Jira now automatically redirects to the Canny Second Life Bug Reports page.
  • Public bug reports (and feature requests) filed via Jira are mostly archived on Github.
    • Due to the different permissions environments within Jira and Github, there are some edge cases which have yet to be archived.
  • Note that any ticket that previously had restricted access e.g. (Linden Only / Originator + Lindens) is not part of this archive.

Game Controller Update

  • Leviathan Linden is working to get an updated viewer this week. Hopefully it will include:
    • Support flycam with new GameControl measurements.
    • Get custom mappings to save to / load from settings.xml.
  • Both of these will bring the code “pretty close” to where he want sit to be for submission to the viewer dev team.
  •  If a new installer is available for download, Leviathan announce it in SL Discord #scripting and also in SL Sports #vehicles.

In Brief

  • A general discussion on the new notecard capabilities within the Gingerbread update, and the results of testing them on Bluesteel regions.
  • Region crossings:
    • User-generated documentation on region crossings and their behaviour is being written-up on the SL wiki.
    • Monty Linden has been untangling results from internal testing, trying to understand what’s part of region crossing and what’s just bugs/mis-design in other areas. He describes his work as “looking good” by potentially requiring further pile-on tests.
    • He has also been trying to simulate massive simultaneous region crossing using libremetaverse.
