The following notes were taken from the Tuesday, September 2nd, 2025 Simulator User Group (SUG) meeting. These notes form a summary of the items discussed, and are not intended to be a full transcript. They were taken from my chat log of the meeting and the video recording by Pantera, embedded at the end of this summary – my thanks to Pantera 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 is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
- The “SUG Leviathan Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
- Meetings are held in text in-world, at this location.
Simulator Deployments
- There are no planned deployment for the week, only restarts.
- The restarts include upgrading some of the hardware to better classes of machines in the background, which is being carried out in stages on each restart.
- Monty Linden noted the Main SLS Main channel restart saw an increase in the mix of more modern AWS hosts, but there were some glitches which led to some regions being off-line for a bit longer than expected.
- It is hoped a new simulator update – Grapejuice – will be ready for deployment to one or more RC channels in week #37.
In Brief
- Rider Linden is working on an official native VSCode plugin for LSL and SLua. This is proceeding smoothly so far, and the hope is to open the repo opened to public viewing as soon as possible.
- Right now, this is just for communicating compile errors from the viewer to the plugin.
- However, he is planning on pushing a lot more through it in the future (e.g. DAP when LUA debugging becomes available).
- He will most likely put in a LSP interface so that it can communicate with Selene for syntax colouring, etc.
- There is a viewer branch with the initial code (PR: https://github.com/secondlife/viewer/pull/4599).
- Leviathan Linden is working on getting the webRTC voice router to automatically submit crash reports in a similar manner to the viewer.
- Pepper Linden noted that:
- Working is continuing on turning on the new dynamic packing, noting there has been a “small road bump” due some issues seen with reported region stats. However, it should be turned on for some RC channel regions this week. Things to look for: better performance/less lag, and less restarts.
- Pepper is currently working on the outfit project for SL Mobile.
- Monty Linden is “thinking about the eventqueueget and other problems” as he re-visits protocol failures again with a view to updating an improving on his previous work in this area.
- User Suzanna (SuzannaLinn) is producing a website with a SLua guide, including examples and a LSL to SLua transpiler.
- A general discussion on SLua event handling, and on state switching (LSL -> SLua) which led to a wider discussion on coding practices and options which ran through the second half of the meeting.
Date of Next Meetings
- Leviathan Linden: Tuesday, September 9th, 2025.
