2024 SL SUG meetings week #38 summary

The following notes were taken from the Tuesday, September 17th, 2024 Simulator User Group (SUG) meeting. They form a summary of the items discussed, and are not intended to be a full transcript, and were taken from my chat log. Pantera’s video is embedded at the end – 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 Tuesday 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.

Simulator Deployments

• On Tuesday, September 17th, the SLS Main channel was restarted without any deployment.
• On Wednesday, September 18th:
  • A new version of the Picnic simulator release (which includes the WebRTC support) called Doubtfire should be deployed to the BlueSteel RC channel.
  • Ferrari and the remaining RC channels will be restarted without update.

SL Viewer Updates

• The DeltaFPS RC, version 7.1.10.10708851543, dated September 11th, was promoted to de facto release status on September 19th. This includes:
  • Performance boosts. Memory management has been optimized and users will experience a higher FPS across various systems. A comprehensive range of bug fixes are also provided. This includes better PBR material handling and resolving frequent crashes. See the release notes for more.
  • UI for scheduling region restarts now available via a new button located in the Region/Estate floater. (Note: there is currently an issue with scheduled region restarts working correctly and a fix is due to come in the next server release).
• Release channel cohorts:
  • None at the time of writing.

Region Crossings Update

We have some attachment fixes available for testing on the Beta grid. Channel is ‘ghi-1419’.Some Blake Sea regions are running on it: Binnacle, Flotsam, Half Hitch, Hawser, Jones Locker, Lanyard, Swab.

Note that these fixes are entirely separate to the general tweaks Monty has been making to improve simulator performance on avatars entering / leaving a region, which are due to be deployed to the main grid soon.

In Brief

Please refer to the video below for the following:

• 2K BoM texture bakes on mesh now available for testing on Aditi (the Beta grid). See my 2K BoM blog post for more.
• A further discussion on attachment losses / attachments getting stuck following teleports. In the case of the latter, Monty suggested a potential workaround:

As for the stuck attachment, there may be a workaround: 1) once stuck, TP to another region (not adjacent), 2) wait one minute, 3) TP back. You may find your attachments in the correct state. But they will get stuck again on re-attachment.

– Monty Linden

• Github issue #1519 (also Canny issue: llDetectedTouchPos returns TOUCH_INVALID_VECTOR when used in touch_start or touch) affecting Touch when in mouselook has been confirmed as a viewer-side issue, and not simulator-side (the viewer is reporting the wrong initial data). However, no current ETA on a fix.
• Rezzing delays affect all scripts in an object is currently being tracked, and Rider Linden indicated he hopes to get to grips with it and have it available for the Barbecue simulator update package. Barbecue (or BBQ, as the notation seems to change between meetings) will be the simulator update to follow-on from the WebRTC deployments currently in progress via Picnic and Doubtfire. This issue sparked a discussion commencing roughly half-way through the meeting.
• Note that the next SUG meeting (Tuesday, September 24th) will be a party to mark the autumnal equinox.
