The following notes were taken from the Tuesday, April 1st, 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 and Pantera’s video, embedded at the end of this piece.
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 April 1st, the SLS Man Channel was updated with the Durian Scones update, which includes the SSL certificate renewal, making it grid-wide.
- On Wednesday, April 2nd, the RC channels will be restarted without any deployment, other than a WebRTC update which will be deployed to the Preflight RC channel.
Planned Updates – LI Calculation Change (Recap)
- Signal Linden highlighted a Feedback Ticket he has raised, proposing the removal of scale from Land Impact calculations.
- This is being possibly earmarked for a simulator update after Durian Scones.
- This essentially means that the LI of object should not dramatically change as a result of resizing (particularly when increased in size). It could also mean that some large objects in world could see LI reductions.
- Understandably, this announcement led to a lot of discussion / debate throughout the meeting.
- Signal also stated that the Lab will like – at some point also take a look at Mesh uploads and use: Incentivize correct use of LODs, which is currently being tracked.
SL Viewer Updates
- Default viewer: 7.1.12.13550888671, formerly the ForeverFPS, dated March 1, 2025, promoted March 5th – No change.
- Numerous crash and performance fixes.
- Water exclusion surfaces.
- Water improvements.
- Second Life Release Candidate viewer 2025.03 version 7.1.13.14115832189, March 28th – NEW.
- 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.
- Second Life Project Lua Editor Alpha, version 7.1.12.13973830462, March 20th, 2025 – no change.
- 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 for linkset larger than the current 64m limit. This would have to be “thought about”, although it led to an extensive discussion on the idea (including issues of linkset visibility / draw distance / limits on older hardware).
Arbitrary link distances sounds like a neat idea, however I suspect such a change would only exacerbate some interest list bugs. I wonder what would happen if two 1cm^3 cubes were linked at 256m. The “position” of the linked object would be one of the prims. Its measure of “visibility” should be… what? The size of one or the size of the linked set?
– Leviathan Linden
- The above led to a broad conversation on prim / object types, physics, prim torturing, etc.
- Signal linden noted on the status of SLua:
Updates on SLua may slow down as we got a lot of good information from the alpha. We need to make some changes and prepare for a beta and production rollout.
- Rider Linden also dropped a request into the meeting:
I’m looking for someone to write an extension. When I open a script file using VSCode check the current workspace. If it finds a file with the same base name, “link” the two files. 1) Copy the file from the workspace to the SL script temp file every time the WS file is saved.
