The following notes were taken from the Tuesday, January 21st, 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 Pantera’s video of the meeting, which is embedded at the end – my thanks to her 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, January 21st, 2025, the simulators on the Main SLS channel were restarted with no update.
- On Wednesday, January 22nd, 2025 the RC channels will be restarted.
- Banana Bread, the next simulator update will be likely be deployed to Aditi for testing.
SL Viewer Updates
- Default viewer: version 7.1.11.12363455226, formerly the ExtraFPS RC (multiple performance fixes, aesthetic improvements and UI optimisations), dated December 17, promoted December 20 – No Change.
- Release Candidate: Forever FPS, version 7.1.12.12793544240, January 17, 2025.
- Numerous crash and performance fixes.
In Brief
Please refer to the video below for the following:
- Leviathan Linden is due to resume work on the problem where content doesn’t always show up on first login/teleport arrival after being asked to look into a couple of other issues. His initial investigations have indicated that the problem is most likely simulator-side, be he’s still digging into the exact cause.
- 2K Bakes on Mesh:
- Pepper Linden confirmed the simulator updates have been approved by QA.
- Pepper also confirmed the viewer update is related to a problem found within the texture pipeline of ExtraFPS using too much VRAM (see this Canny issue report). This fix is due to go into the Lab’s ForeverFPS viewer update, and LL would like Firestorm to include it in a release before switching on 2K BoM.
- There is some confusion as to the status of the glTF scene import project in the wake of Runitai Linden’s departure from LL.
- Runitai got as far as prototyping the capability on Aditi, but it was not tied into the physical engine.
- As has been mentioned numerous times, the majority of the focus within the graphics / viewer teams has been on improving overall viewer performance and is currently geared towards assisting Firestorm deal with blocker to their ExtraFPS release.
- The above led to a discussion on the value of including some form of 3D mesh editing tool in the viewer. Unsurprisingly. These discussions saw a range of viewpoints expressed.
- Leviathan Linden intimated that the viewer-side work for his game controller updates (which are available server-side) is also pending on resources within the viewer team becoming available in order to make the game control options more easily accessible (e.g. with the official viewer, it has to be unlocked via the Advanced menu).
- A discussion on properly-supported “walking / running backwards” animations states.
- It was suggested that the server-side Luau work (scripting) could be deployed to Aditi “in the next few months (possibly)” to allow scripters to poke at it while it is still in development.
- Requests for additions to the official viewer, including RLV (RLV/a has been contributed by Kitty Barnett for inclusion in the official viewer, but the status of the work in doing so is unclear – it’s a significant piece of work).
- A reminder that Monty Linden is working to correct defects within EventQueueGet (a simulator Capability that delivers messages from a simulator to viewers over HTTP using a long-poll scheme. It is core functionality without which viewer/simulator coordination is impossible), and is seeking feedback – see here for both defects, proposals to resolve and how to test.
