2026 week #26: SUG meeting summary

The following notes were taken from the Tuesday, June 23, 2026 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 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

• The Loganberry RC is now grid-wide.
• The next simulator update will be called Mango.

In Brief

• Rider Linden:
  • Has some fluent interfaces for the Lua project, with what he believes is a final version, with a PR in lsl_definitions.
  • Is now going to his object publishing work (a websocket API, to edit objects and their inventory, to allow things like vscode to see inworld objects and their contents etc., see here).
  • Note that this API will not recognise remote connections, but should be between the viewer and an external editor running on the same machine.
  • He also noted that LSL function interfaces and Lua function interfaces are both built from the same source file. So anything in one, should be available in the other.
• Leviathan Linden:
  • Has added added OBJECT_LOCKED to llGetObjectDetails() via the Lua project. The new enum is available to LSL and will work in the mono runtime… but it won’t be delivered until the Lua project ships.
  • Has also been working to port Wolfgang’s game-control work from Alchemy to the official viewer game-control project. This is a work in progress, and some changes will be required.
  • Still needs to do some follow up work on Navmesh crash fix he was working on in week #23.
• Roxie Linden noted that:
  • The WebRTC team is still working on some evaluation of options for voice-to-text transcription.
  • This work is still very much at the experimentation stage, so people should not expect to see it suddenly appearing.
  • There will need to be some tuning of sound filtering and voice activity detection for any transcription service to work, but this should not affect Voice quality.
• Harold Linden (LUA):
  • Has mostly been on housekeeping work.
  • Is going to merge the work from the Lua branch back into the main server branch (with Lua still flagged off) so they get out of sync less.
  • He also plans to pull the new Luau changes from upstream since LL is a little behind with this.
  • Noted that as well, classes and Lua integers will be flagged off until they firm up, but the code will be part of the repo.
  • Noted in the general discussion that the Lua scheduler only gets one time slice per frame (its the same scheduler as used for Mono).
  • Overall, believes the project is now approaching “release quality”.
• Monty Linden noted that lsl-definitions have been updated recently but not baked into a release and cycled around yet – this will happen “soonish”.

General Discussion

Please refer to the video below for  more on the following.

• The issue of teleport disconnect viewer crashes was raised again.
  • As has been previously noted within SUG meetings, there is no singular cause of TP disconnects  / crashes. LL have been looking into causes and have been working to fix some of the causes.
  • Anecdotal evidence indicates that recent fixes have (in the current release viewer – “Flat UI”) have helped improve some issues.
• There have been reported of IM chat failures occurring with the notification: Chat Session Aborted.
  • Two causes for these issues have been identified, and a fix for one was released as part of the Loganberry simulator update.
  • LL is actively working on the second, which appears to be one of the IM chat server misbehaving. The hope is that a fix will be deployed soon.
• There was a discussion around the Lua scheduler (some of which is noted above) between 34 and 42 minutes of the meeting.
• A general discussion on animations, including the potential for Lua to simplify things by using fewer scripts and for WIBNIs such as an IK system that simply directs where body parts should be (e.g. “bum on this cushion; elbow on this armrest”).
  • This included a discussion on llGetVisualParams, revocation of scripted animation permissions, etc. Please refer to the video.

Date of Next Meetings

• Leviathan Linden: Tuesday, June 30, 2026.
• Formal SUG meeting: Tuesday, July 7, 2026.
