The following notes were taken from the Tuesday, May 13th, 2025 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 of the meeting. Pantera also recorded the meeting, and that recording is embedded at the end of this piece – my thanks to Pantera, as always, for providing it.

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):
  • Every Tuesday at 12:00 noon SLT.
  • In text (no Voice).
  • 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.

Simulator Deployments

• On Tuesday, May 13th, the Main SLS channel was updated with the Elderberry simulator release.
• Om Wednesday, May 14th, the RC channels should be restarted without update.

Upcoming Deployment – Fig Newton (2025.06)

• Yes, the name changed in the passage of a week.
• This is still being put together, and is unlikely to surface before June, as the simulator team has been focusing on some necessary internal work which has drawn attention away from feature work on the simulators.

SL Viewer Updates

•  Default viewer: 2025.03 7.1.13.14343205944, issued April 9th and promoted April 15th.
• Release Candidate: 2025.04 – 7.1.14.14911904105, updated May 13th 2025.
• Second Life Project Lua Editor Alpha,7.1.12.14888088240, updated May 13th 2025.
  • Will only work on Aditi. Blog post: Lab officially announces Luau Alpha testing.

In Brief

• Rider Linden requested if people preferred code-names for simulator updates or their official initial version numbers (e.g. 2025.05, 2025.06).
  • Given that version umbers actually relate to minor things like RELEASE NOTES – they actually serve a use.
  • As noted by Fig Pudding Newtons, code names can change on a whim and seem pretty pointless.
  • However, it appears an attempt to use both will be used going forward 🙄(yes, I’m a carbon-based unit and I have no sense of fun‡).
• PBR Colour data is lost when setting PBR overrides was raised some time ago, but has yet to be fixed. Responding to a question on why it had not been fixed when implementing llSetLinkGLTFOverrides, Rider Linden stated:

Because when PBR was implemented they did not separate the colour value from the alpha. The two are stored internally as a single number. Since the simulator does not have the actual value from the material (it does not read materials) there is no way to change one without impacting the other. Doing so would have required a protocol change in the way overrides are sent and protocol changes are big deals since they break the viewer.

• • He went on to note that overrides are among a number of things he would like to revamp and improve upon.
• The above led to a request for creators refreshing older products with PBR to be able to supplement llSetLinkAlpha to some sort of llSetLinkPBRAlpha, without having to “dual stack” materials.
  • Rider Linden indicated that this would require adding a new function, and as such perhaps best done when overrides are being revamped, per the above comment.
  • Leviathan Linden further noted that Geenz Linden is currently thinking about how to overhaul GLTF override system, as fallout of planning on how to support object hierarchy.
• A portion of the chat was around When an object is paid the object name being recorded should be controlled by the Server and not the Viewer, seen as a particular concern among providers of Skill Games. This topic was also raised extensively at the Skill Gaming meeting.
• Most of the meeting revolved around Blinn-Phong, glTF, alpha and colour overrides, most of which I, frankly, am not qualified to talk about in a meaningful way. Please refer to the video.
• The latter half of the meeting involved the potential for physical region crossings between regions that are non-contiguous (e.g. your are on “Region A” and can “see” and “cross into” (walking, via vehicle) “Region B” directly (no actual manual teleport trigger), even though “Region B” is on the 2other side” of the grid. See: “Wormhole Regions” (Non-Cartesian region crossing).
  • This is something that has apparently been raised a lot within LL and seen and a “neat idea” and potentially possible. But it would be “way down on a list, below all sorts of important stuff to fix.”
• Leviathan Linden is still trying to work out the “sometimes objects don’t show up on login” problem. He now has a reliable repro for this issue and is using it to try to understand why and where things are going wrong.
• Off-lines not appearing on log in until relogging his become an increasing issue of late.  Commenting on the report, Leviathan Linden stated:

The fact that the off-lines show up in a second session suggests that they were never successfully requested by the viewer in the earlier session, since otherwise they would have been cleared (considered delivered) at the server. So we’re wondering: why isn’t the viewer correctly invoking some cap?

Simulator Deployments

• On Tuesday, May 6th, the Main SLS channel was restarted without any update.
• On Wednesday, May 7th:
  • BlueSteel and the snack channel running the Elderberry simulator update (see below) should be restarted.
  •  All remaining RC channels should be updated with Elderberry.

Elderberry Update (2025.05)

• A new option to llDerezObject – DEREZ_TO_INVENTORY, which returns the targeted object to inventory and saves its current state (e.g. has the same behaviour as Build → Object → Save Back to Object Contents.
• llIsLinkGLTFMaterial  – which can can determine if a face on a linked prim is PBR.
• REZFLAG_DIE_ON_NO_REZZER – which will cause a rezzed prim to die if its rezzer is no longer present in the region.
• llSetGLTFOverrides, rather than changes to llSetColor and llSetAlpha to work with PBR, as changing the latter was “starting to lead down some very scary paths WRT ‘What is the right thing to do'”.
• Possibly a fix for llSetGroundTexture, which currently has the NE & SW values swapped. The question was asked in this was in the release, but the question wasn’t fully answered.

Upcoming Deployment – Fig Pudding (2025.06)

• This is still being put together.
• The update is unlikely to surface before June, as the simulator team has been focusing on some necessary internal work (e.g. ensuring various repositories build and deploy via Github actions correctly; updating where docker images are stored) which has drawn attention away from feature work on the simulators.

SL Viewer Updates

•  Default viewer: 2025.03 7.1.13.14343205944, issued April 9th and promoted April 15th.
  • New UI element for water exclusion surfaces: Build / Edit floater → Texture Tab → Hide Water checkbox.
  • The maximum amount of Reflection Probes can now be adjusted to better accommodate low VRAM scenarios.
    • Values will be set automatically depending on your chosen graphics quality. OR
    • Use Preferences → Graphics →  Advanced Settings →  Max. Reflection Probes to manually set.
  • An issue with being unable to see Sky Altitude values in the Region/Estate window has now been resolved.
  • Preferences → Graphics → Max. # of Non-Imposters has been renamed Max. # of Animated Avatars for clarity.
  • Bug and performance fixes and memory optimisations.
• Release Candidate: 2025.04 – 7.1.14.14742193597, May 2nd 2025 – NEW.
  • Includes the following new features:
    • Chat Mentions (Early Support): Type @ then pick a name. To follow: audible alerts and highlight colour pickers.
    • My Outfits subfolders: now supports the use of subfolders.
  • Key updates:
    • Build Floater improvements: increase to scale boundaries; Physics Material Type now updates when selecting linked objects; Repeats per Meter value no longer incorrect for non-uniform sized objects
    • Hover height: the minimum/maximum is now +/- 3 meters.
    • Snapshot floater: L$ balances can be hidden independently of the rest of the UI.
    • Preference Search bar: general usability and readability improvements.
  • Refer to the release notes for full updates and fixes.
• Second Life Project Lua Editor Alpha, version 7.1.12.14175675593, April 2nd.
  • Will only work on Aditi. Blog post: Lab officially announces Luau Alpha testing.

In Brief

• A request for SLua events to be updated along the lines suggested in this canny request. Rider Linden indicated that a update will be made prior to SLua moving to wider beta testing, and will likely It will likely end up looking similar to the Canny proposal. However, there is no current time frame as to when the update will be made.
• A Canny request was filed in January for a llGetRegionWorldMapTile feature. This was reportedly now sitting in the backlog of requests and work the server team are hoping to work through in time.
  • This saw a follow-up request at the meeting to be able to zoom down to the level of centring a parcel on the map. Rider indicated that it should be possible to give the full region map as a as a texture ID, allowing scripts to adjust the offset and scale of the texture to achieve desired results.
• A discussion on regions idling (at 1 FPS(?)) when not in use (e.g. when there are no avatars in the region, no child agents registered with in and no HTTP IN/OUT functions running); the ability for llGetEnv to obtain a region’s status.
  • Regions are not completely shut-down when “empty”. as most require scripts to keep running.
  • This broadened into a discussion on how low a region takes to start-up. The most accurate might be “no long in the scheme of things, but variable”.
• In response to a question on progress with combat 2.1 features, Rider stated:

Combat 2.1 is pushed back. I’ve got no eta when that will come back up. I’d like to get it moving, I think it introduces some important additions that have impacts outside of just Combat, but there are lots of things that need doing and I can only type so fast.

• The latter half of the meeting was taken up with discussions of texture loading, the impact of alpha layering, non-optimised contents and similar, the majority of which was more viewer-centric. They arose from a complaint that Fantasy Faire is overloaded with “4K textures” (which aren’t actually a thing in SL) causing viewer performance issues.

In Brief

• A (reasonable) request was made to have simulator release names (“Elderberry”, “Puff Pastry” or whatever) actually reflected on the release notes rather than referencing them solely by release number.
• Questions llDerezObject() DEREZ_TO_INVENTORY:
  • Is the clean-up procedures after de-rezzing any different to other objects? Should not be, the; the object is killed from in-world on receipt of the derez command, then a new asset is generated to replace the deleted one in the rezzing object’s inventory.
  • Is DEREZ_TO_INVENTORY to to any capability? No. The code was originally set up to respond to a message from the viewer and so would report messages back that way; however it is being updated to be smarter than that to avoid missed messages, etc.
• A feature request to allow attachment rezzing directly from another object’s inventory has been received (e.g. to assist with changing outfits). It is regarded as a large project and, if accepted, has yet to be added to the development roadmap.
• A feature request to Add function to get a list of objects in the region (somewhat similar to the Area Search in some TPVs) has been submitted and is currently being tracked. Upvote if you’d like to see it get onto the roadmap for implementation.
• A discussion on prim manipulation and LSL and differences between viewer-side and simulator-side disconnects (e.g. LSL cant set sphere taper, and viewer can’t set floating text or particle). This drifted into discussion of prim / linkset ordering and an actual node hierarchy for the same that is known to the viewer, together with a means to set the linkset number for a given object in the linkset / “click and assign” root prim for a linkset.
• Leviathan Linden offered some feedback to those testing the SLua regions on Aditi:

One thing I was working on a week or two ago but currently on hold: people on the Lua servers were using the faster scripts to thrash a log of prim properties, which would generate a storm of Full Updates. Someone noticed some hot spots in the generation/sending of those updates, slowing things down making the problem look like Lua’s fault. So, I was working on a speed-up there. Wasn’t done, got side-tracked. Will get back to it.

In Brief

Please refer to the the video for details on the following.

• Ability to rename a group is marked As Planned, but “is not currently in the queue right now”.
• A request to make gravity / physics variable on a region basis (or as least when underwater. The response to this was twofold:
  • File a Feature Request outlining the requirement and how it might be used (e.g. through the SL Experiences mechanism) and see what the feedback from the community might be.
  • Whether the work could be undertaken or no would depend on a combination of how feasible it would be; the effort required to implement it (particularly in relation to other requests); how it might be employed.

The physics engine can handle a different acceleration of gravity, no problem. But, we’d have to track down all the places where we have hard-coded the normal value of gravity (server and viewer) and then replace that with a value that is communicated from the server, so we’d have to adjust the data protocol a bit, then get that work in all the important TPVs. Just thinking out loud how hard it would all be.

– Leviathan Linden

• The above threaded through much of the meeting, in placing crossing over  into discussions:
  • About facilitating natural swimming in SL (i.e. Linden Water shouldn’t exhibit the same gravity as land and causing avatars to drop to the riverbed / sea floor).
  • The idea of the official viewer providing a built-in AO system (e.g. akin to Firestorm’s, but making use of llSetAnimationOverride.
  • On the SL wind and its usefulness (and to the ability to have wind-driven weather).
• The official Discord channel has seen a conversation about allowing experience scripts to optionally rez objects as the experience land owner, rather than only the owner of the object (e.g. let an experience gun rez bullets under land group instead of needing to set land to open rez). Rider Linden stated he’d like to get something like this added to the roadmap.
• Although more viewer-side, the camera became a focus of discussion:
  • While no work has been taken on it, New llSetCameraParams() rules: CAMERA_POSITION_KEY and CAMERA_FOCUS_KEY is something that might be a part of providing better camera controls for the likes of machinimatographers.
  • A reminder was given, as well: llSetKeyFramedCamera.
  • Leviathan Linden remided people that he had re-implemented follow-cam in the game-control project, so that the camera could be moved around with the game controller device. However, “there was much work to be done there to make anyone happy”.
• The viewer-side implementation of Lua (not the server-side SLua project currently being tested on Aditi), is apparently “on hold”.

Upcoming Deployment – Recap

This next simulator update will be called Elderberry. Among other things, this should include:

• llIsLinkGLTFMaterial  – which can can determine if a face on a linked prim is PBR.
• REZFLAG_DIE_ON_NO_REZZER – which will cause a rezzed prim to die if its rezzer is no longer present in the region.
• Updates to llSetAlpha will have a caveat: if alpha  is set to >0.85, it will switch the overrides to opaque; setting under that value sets them to blend. This is because there seem to be some serious rendering issues with blend mode and an alpha near 1, per this image.
• llSetGLTFOverrides, rather than changes to llSetColor and llSetAlpha to work with PBR, as changing the latter was “starting to lead down some very scary paths WRT ‘What is the right thing to do'”.

SL Viewer Updates

• Default viewer: 2025.03 version 7.1.13.14343205944, dated April 9th, 2025, promoted April 15th, 2025.
  • New UI element for water exclusion surfaces: Build / Edit floater → Texture Tab → Hide Water checkbox.
  • The maximum amount of Reflection Probes can now be adjusted to better accommodate low VRAM scenarios.
    • Values will be set automatically depending on your chosen graphics quality. OR

• Second Life Project Lua Editor Alpha, version 7.1.12.13907344519, April 2nd.
  • Will only work on Aditi. Blog post: Lab officially announces Luau Alpha testing.

In Brief

Please refer to the the video for details on the following.

• A general discussion llDerezObject and whether an object being taken back by an object has been renamed will result in a copy being generated, or the original still replaced (answer: still replaced).
  • As a result, a DEREZ_TO_INVENTORY_COPY parameter has been requested, and could be suppled in the simulator update after Elderberry.
  • Rider Linden also noted he may need to disallow a reclaim on coalesced inventory objects, as once in-world, acoalesced object becomes a grouping on independent objects, with not connection between them or any means to re-group them.
  • Discussion around this functionally and iiDerezObject continued through most of the meeting.
• Progress on SLua is described as being “good”, but as per the pervious meetings (SUG and TPVD), there is more back-end work to be done before the SLua project moves to a “beta” on Aditi.
• Following the discussion on World → Show → Land Owners has been broken since the release of PBR such that all owners, regardless of type are only shown as red, rather than in different colours based on ownership (see Land owners colour),  it was noted that a fix for the issue should be in the next RC viewer update – 2025.04.

  • llSetAlpha will have a caveat: if alpha  is set to >0.85, it will switch the overrides to opaque; setting under that value sets them to blend.
  • This is because there seem to be some serious rendering issues with blend mode and an alpha near 1, per this image. Rider Linden added:

Also. It bears repeating… since I forgot. BP colours (what you set with llSetColor) are in sRGB space. PBR is linear. I’m doing the conversion internally so it should be the same colour in both cases.

SL Viewer Updates

• Default viewer: 7.1.12.13550888671, formerly the ForeverFPS, dated March 1, 2025, promoted March 5th – No change – crash and performance fixes; Water exclusion surfaces and water improvements.
• Second Life Release Candidate viewer 2025.03 version 7.1.13.14174767759, April 2nd.
  • New UI element for water exclusion surfaces: Build / Edit floater → Texture Tab → Hide Water checkbox.
  • The maximum amount of Reflection Probes can now be adjusted to better accommodate low VRAM scenarios.
    • Values will be set automatically depending on your chosen graphics quality. OR

  • Bug and performance fixes and memory optimisations.
• Second Life Project Lua Editor Alpha, version 7.1.12.13907344519, April 2nd.
  • Will only work on Aditi. Blog post: Lab officially announces Luau Alpha testing.

In Brief

Please refer to the the video for details on the following.

• A request was made to have changes to releases on the SLua test regions on Aditi added to the release notes mechanism so that those using the regions can see when / why things are going to change or are going to change.
  • This is going to be looked into. In the interim, Rider Linden is going to try to to provide notification of updates to the Second Life Discord server.
• World → Show → Land Owners has been broken since the release of PBR such that all owners, regardless of type are only shown as red, rather than in different colours based on ownership (see Land owners colour).
  • No update in fix status.
• Add flag to llSetLinkSitFlags, SIT_FLAG_INVISIBLE is described as on the to-do list, and will likely be a viewer-side change so the flag is respected.
• A status update was requested for work on providing a means to ease issues of ban line collisions and vehicle loss, and having the simulator provide more timely information on parcel access permissions before a vehicle is on top of a parcel in which access is denied for the avatars riding it.
  • This is something Rider Linden is hoping to get to in the simulator release after Elderberry).
  • The discussion broadened through the when and how the simulator should provide parcel information to the viewer – e.g. in general or on demand, and what information could be provided, having a mandated delay on security systems on the Mainland to prevent the enter parcel / immediate teleport / ejection situation.
• Still no news on when the Mainland legacy EEP setting (now seen as dim and murky post PBR deployment), although it is believed the Moles are working on Mainland region settings.
