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 – no video this week.
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. Although the Main channel apparently had some issues on Tuesday July 22nd, leading to multi restarts for some regions.
In Brief.
- Rider Linden is working on a few new script features that the moles need for an upcoming project. These mostly deal with land and being able to transfer or sell land using a script.
- Pepper Linden has been working on a re-write of LL’s Conductor service, and is currently wrapping this up as it goes through QA. The Conductor service is responsible for placing regions onto servers, and the re-write is designed to allow the team responsible to more optimally place regions and prevent things like ‘hot-spots’ (e.g. one region on a host using more resources than it should and starving other regions of CPU time).
- Signal Linden is working on number of projects:
- Making “shovel-ready” tasks for open source contributors. This includes: bringing back legacy search; implementing drag-and-drop uploads; resizing large textures before uploading; etc.
- Looking at bounty/reward platforms for compensating people for working on initiatives LL hasn’t got much traction on.
- Getting budget approval for taking SLua to production and merging some “nice small fix-up PRs” on the LSL-definitions repo.
- The idea in having a series of defined tasks for contributors is to have more people contributing upstream to the viewer and providing “ready to go” code and thus free the Lab’s core viewer team to focus on larger viewer projects.
- Having the ability to replace mesh / prim HUDs with something more suitable was discussed. One suggestion has been the development of an HTML5/CSS/JS solution of some sort. However, this would require quite a bit of both viewer and server work; as such, a proof of concept from the community would go a long way towards getting some server attention on it.
- Some concerns were raised about this leading to people having to connect to unknown external websites.
- Another suggestion was for a small mobile subset of SVG within SL, although this is a potential awkward solution as it doesn’t allow thing like buttons lighting up on HUDS when moused-over.
- This led to a discussion on options (HYML5, SVG, some form of modal system built-into the viewer, using MOAP / CSS, with various opinions being expressed.
- glTF mech import:
- As reported in my CCUG meeting notes, this is to go to “beta” with the next viewer update.
- Full glTF scene import is regarded as “seriously deprioritised”, with Signal Linden expressing a preference for keeping it so until it can be implemented server-side.
- There s a report that a change in the glTF uploader broke the glTF scene rendering. no further details available.
- The plan to replace the SL Wiki (powered by Media Wiki) with a new documentation platform was discussed (see: Modern Documentation Platform: docs.secondlife.com).
- As of the next official meeting, the Simulator User Group will be at a new location (still TBC at the time of writing). What this should look like was a source of extended discussion, as was whether or not Simon Linden’s home (the meeting place until now) should be left intact or destroyed (“destroyed” won that part of the discussion).
Date of Next Meeting
- Tuesday, August 5th, 2025 – venue TBA (check the SL Public Calendar and/or User Group wiki page for updated SLurl).
- Unofficial meeting (TBC): Tuesday, July 29th, Venue: TBC.
