Meeting Purpose
- The Open Source User Group (OSUG) meeting is an open discussion of Second Life development, including but not limited to open source contributions, third-party viewer development and policy, and current open source programs.
- This meeting is generally held twice a month on a Friday, at 13:00 SLT at the Hippotropolis Theatre and is generally text chat only.
- Dates and times of meetings are recorded in the SL Public Calendar.
Official Viewer Status
- Default viewer 26.3.0.31203661088, August 10, promoted August 17 – quality of life improvements; performance improvements; bug fixes – NEW.
- Second Life Lua Editor Alpha viewer 26.3.0.32302693173, August 21 – NEW.
Viewer Notes
- The Lua Editor viewer is now classified the 26.4 viewer in the release pipeline.
- The Project / alpha version of this viewer was updated on August 21, 2026.
- This viewer will be the first official viewer-in-flight will see the return of Linux support for the official viewer.
- A caveat with Linux was given that LL will “be giving the Linux viewer as much QA love as Mac and Windows”.
- Graphics Care Package:
- Geenz has been bug fixing but still has “some work to do on getting mirrors into a good place”, particular around avatar rendering in mirrors.
- Screen Space Reflections (SSR) also have some further updates, with some enhancements to transparent SSR.
- The plan remains for the GCP viewer to remain a Project / alpha viewer for some time once available to allow for feedback.
Other Items
- Game_control: Leviathan Linden has been engaged in other simulator work, so no further moves on this work, simulator or viewer, for reporting at this meeting.
- Roxie Linden noted that “Some good work on evaluating models for transcription is still going on”.
- See also my notes on the previous OSUG for updates on transcription and translation tools.
- Transparent Media on a Prim (MOAP) – the ability to have parts of a MoaP surface be transparent rather than the whole thing – this is still sitting with LL’s internal processes, so no updates in terms of security updates, etc.
- However, there is a possibility this work could be included in the 26.4 GCP viewer; this appears to be dependent on resources and – particularly – performance impact (so even if shipped, it might be disabled by default).
- Callum Linden is working on Chrome Embedded Framework (CEF) updates.
- There was a general discussion on CEF and its associated Dullahan process – particularly the number spawned by the viewer (which can be a lot due to the nature of CEF) and reports that not all Dullahan process may be getting killed / culled when the viewer no longer needs them / has been closed.
- There was a general discussion on SSR and rendering which got into the long grass over approaches, options and performance. In short, Geenz is trying to enhance performance for a more general use of SSR (many have used it primarily to improve the look of Linden Water, although the moiré effect introduced with PBR rendering has tended to reduce this use in recent viewers).
Next Meeting
- 13:00 SLT, Friday, September 4, 2026, at the Hippotropolis Theatre.
