The following notes were taken from the Tuesday, February 11th, 2025 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 Pantera’s video of the meeting, which 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, February 11th, 2025, the simulators on the Main SLS channel were restarted with no update.
- On Wednesday, February 5th, 2025 the Banana Bread update should be deployed to the remaining RC channels, having been deployed to BlueSteel RC last week) This update includes expansions to llGetObjectPermMask that let you get an object’s permission mask taking into account the permissions on its inventory, and that ability has been added to llGOD.
Upcoming Deployments
- The simulator update to Banana Bread is called Carrot Cake.
- Development on this update has been “accelerated” such that an initial deployment to the BlueSteel RC in week #7 (commencing 17th, February 2025).
- This update should include llSetGroundTexture – this will allow a region owner/EM to set and adjust ground textures on a region, including some of the PBR features like rotation, offset and scale.
- Monty Linden indicated his work on EventQueueGet (a simulator Capability that delivers messages from a simulator to viewers over HTTP using a long-poll scheme. It is core functionality without which viewer/simulator coordination is impossible) is to be rolled into Carrot Cake. He further indicated that he plans to update the SL Wiki documents on EventQueueGet as time permits.
SL Viewer Updates
- Default viewer: version 7.1.11.12363455226, formerly the ExtraFPS RC (multiple performance fixes, aesthetic improvements and UI optimisations), dated December 17, promoted December 20 – No Change.
- Release Candidate: Forever FPS, version 7.1.12.12999043440, February 4, 2025.
- Numerous crash and performance fixes.
- SL Mobile (Beta) version 2025.1.542 / 0.5.533 – Create / Delete accounts, fixes – February 4, 2025.
In Brief
Please refer to the video below for the following:
- llGetEnvironment (+ related functions) return inaccurate unit vectors for sun / moon position is still awaiting action.
- Requests were made for LSL capabilities for manipulating the upcoming llGroundTexture.
- There was a report that the entire SLS Main Channel was restarted a second time during week #6. However, Rider Linden indicated that a number of regions were moved between servers, which prompted restarts, but there was no additional LL-lead restart of the entire channel.
- There are reports that there is a bug with llRezObjectWithParams: in using REZ_POZ with the local flag set TRUE, the rezzed object is positioned against in-world coordinates instead of rezzer local coordinates. So, for example, if the rezzer is aligned with world coordinates, the object arrives where expected, but if the rezzer is rotated, the object continues to arrive at the unrotated position. A bug report has been requested on this.
- Rider Linden noted that there is liable to be Lua server-side scripting engine news “soon”. This was followed by a general discussion on the project.
- Leviathan Linden has confirmed the viewer is dropping packets when it gets spikes of UDP data. He is going to try to provide a patch for viewers to prevent this, but also needs to look into the server behaviour to try to determine why and how the data spikes are happening. This sparked a discussion on UDP, packet loss and bandwidth which ran the most of the meeting.
- A request was made for the status of much-needed PBR-related LSL functions (plus easy PBR alpha-switching and PBR override permissions). The response was an agreement that they are needed, but not on an “immediate” queue for implementation.
