2026 week #23: SL CCUG meeting summary

Meeting Purpose

• The CCUG meeting is for discussion of work related to content creation in Second Life, including current and upcoming LL projects, and encompasses requests or comments from the community, together with related viewer development work.
  • This meeting is generally held on alternate Thursdays at Hippotropolis and is held in a mix of Voice and text chat.
• Dates and times of meetings are recorded in the SL Public Calendar.

Official Viewer Status

• Default viewer  – 26.2.0.25386466510, May 19 -“flat” UI and font update.
• Second Life Lua Editor Alpha viewer 6.1.0.23768336784, April 29.

Viewer Notes

• Viewer 26.3.0 (performance improvements) remains the priority for issue and later promotion. This viewer will include async inventory loading, which should further help with loading very large inventories; together with new texture streaming updates which should help those on SL minimum specification computers with constrained VRAM.
• Beyond this, there are on-going discussions within the Lab as to priorities for the viewer train going forward.
  • This might see the Lua Editor and the Linux updates for the viewer get merged into the Develop branch. However, if this does happen, it should not be taken to mean Lua is on the cusp of being formally released; rather it will will mean that the viewer side gets released within a viewer ahead of the back-0end support going grid wide (the latter loosely seen as being in the late summer at the earliest).
  • Setting feature flags within the viewer to gatekeep upcoming features and functionality until such time as it is generally available (as would be with the Lua code mentioned above) is also being discussed.
• The Graphics Care Package Viewer (GCP) is effectively “on hold” for the present. However, it might see some additions made to it, such as the glTF transmission work (which will depend on the overall performance impact).
• Maintenance releases are also in development. As has been indicated in past CCUG and Open Source meetings, these will be much smaller updates to the viewer, aimed at offering a more limited number of fixes  (e.g. the top 5 or 10 issues / viewer crashers) than has been the case with past maintenance viewer updates. The first of these is probably going to be viewer 26.3.1 (i.e. following 26.3).

General Discussions

• Kyle Linden confirmed the Second life Creation portal (/Getting Started with Scripting) has seen a lack of outward communications from LL, but the Lab definitely wants to proceed with building it out and does want to receive contributions. To this end he will be contacting those known to have produced documentation on things like Lua, and this work will be progressing in the near future.
• It was requested that the upcoming rendering updates within the GCP viewer all have options to disable them if people do not wish to use them.
  • Geenz pointed out that rather than options to disable, all of the items with could impact performance (such as glTF transmission) will have drop-down options within Preferences, allowing their quality, to be lowered, limiting any performance impact. However, some capabilities (e.g. glTF metallic) will remain enabled at all times, as they are viewed as essential to content.
• A general conversation about possibly reintroducing texture sampling / supporting glTF texture filtering, plus looking beyond OpenGL together with upscaling resolution via the likes of AMD’s FSR, Nvidia’s DLSS, Intel’s XeSS, etc. See here for more), with Geenz noting the with the deprecation of OpenGL, LL is getting increasingly constrained as to what they can do, although FSR is a “maybe”, as there has been some backporting of support to OpenGL.
  • The above being said, LL is currently still looking at API options (e.g. Vulkan / Metal /  WGPU (the latter being seen as  suiting a wider mixed of older hardware can address multiple APIs)), although the focus at the moment is on finding a good inflection point to determine the direction which should be taken (such as Apple finally finally ending their support of OpenGL, rather than deprecating it but still supporting in through Mac Os 14 Sonoma).
• Conversations not directly related to content creation included Nvidia’s new CPU/GPU ARM chips and how they may affect hardware (and Windows support) in the future; availability of Second Life OpenSpace regions; whether Second Life can have regions larger than 256×256 sq m (not on the horizon).

Next Meeting

• 13:00 SLT, Thursday, June 18th, 2026, at the Hippotropolis Campsite.
