Day: July 16, 2025

The following notes were taken from the Tuesday, July 15th, 2025 Simulator User Group (SUG) meeting (“off week”). They form a summary of the items discussed, and are not intended to be a full transcript. The notes were taken from my chat log of the meeting and Patera’s video, which is embedded at the end of this article – 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 other Tuesday from July 8th, 2025, 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.
• The term “off week” is used to describe meetings held by Leviathan Linden on those weeks when a “full” Simulator User Group meeting is not scheduled to be held.

Simulator Deployments

• There are no planned deployments to any channels this week, only restarts.

SL Viewer Updates

• Default viewer 7.1.15.15596336374 promoted June 12 – No Change.
• Second Life Project glTF Mesh Import, version 7.1.14.15976006598 July 2 – No Change.
  • This is an early Alpha release with some of the rough edges and already resolved many bugs and crashes, although more are to be found, together with general feedback from the community. Please read the release notes if you intend to test this viewer.
• Second Life Project Lua Editor Alpha (Aditi only), version 7.1.12.14888088240, May 13 –  No Change.

In Brief

Also refer to the video for the full meeting.

• Leviathan has been working on resolving a exploit which – although this is not certain) he may have accidentally introduced into the simulator code during her first stint at the Lab(!).
• Further work on the game_control project for the viewer remains in hibernation.
  • The core code was in a viewer development branch that was archived during the most recent switch to the viewer development and release workflow.
  • While much of it has been “salvaged” from the retired dev branch, it still needs to be approved for porting and merging into a current development repository.
  • There are also functional questions to be addressed – such as what to do about keyboard-only users and game_control.
• Work on the Linux version of the official viewer also appears to be “stuck” in the archived develop branch.
• Leviathan asked if anyone has tried to use the SL raw terrain save/load system, and if so, whether they have found it works correctly. There are apparently some bugs within it, and he’s trying to determine how best to prioritise it for fixing.
  • The general consensus at the meeting was getting the OK to update, port and merge the game_control code should be a higher priority than the terrain save/load.
• A general discussion on porting features / capabilities to / from Firestorm (and on offering Pull Requests to Firestorm for code such as game_control).
• A brief indication of “prioritisation competition” for viewer-side features at the Lab: some developers prefer to develop the code and build a functional UI to access it, then polish the latter; others (and management?) prefer code that is put forward with a complete, polished UI design.

Date of Next Meeting
