The following notes were taken from the Tuesday, May 27th, 2025 Simulator User Group (SUG) meeting. 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 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
- There are no planned deployments to any channels this week, only restarts.
The team has been working on a lot of backend work getting things rebuilt for a more modern artifact management solution (think: rebuilding docker containers, libraries, etc.) –this is ongoing work. We also are doing more invisible work updating hardware to a newer configuration.

SL Viewer Updates
- Default viewer: 2025.03 7.1.13.14343205944, issued April 9th and promoted April 15.
- Release Candidate: 2025.04 – 7.1.14.15192634334, May 25 2025 – Updated.
- Second Life Project Lua Editor Alpha (Aditi only), version 7.1.12.14888088240, May 13 – No Change.
In Brief
- A useful Feature Request: Log in Screen: “Region Offline” or “Region Restarting” warning prompt – vote!
- A question on whether or not a viewer should expose the channel llDialog is operating on, or whether that is private information. Short answer: no it is not private; it’s in the viewer.
- A debate as to how many regions run on a simulator and how many simulators run on a server, after a claim was made it is not 1:1:1.
- Leviathan Linden: SL runs one Region per Simulator process. The actual Server (machine) runs multiple Simulators.
- Monty Linden: the old 1/core vs 4/core is long gone – departed with uplift.
- Confusion was voiced about region crossings and the idea that an avatar’s inventory is “handed over” between regions. This is not the case; only object inventory (scripts in your attachments) is transferred.
- The confusion may have arisen by conflating issues of inventory size causing issues at log-in (which the Lab has been investigating) with the idea that the same is true for region crossings.
- WebRTC “switch on” is still being held – currently because it still needs some bugs fixed; LL is looking to get the infrastructure sorted for a wider deployment across regions and is also looking at performance optimisations (as well as the issue of around 21% of Firestorm users not running a WebRTC capable version of that viewer).
- A lot of general chit-chat about myths, frame rates, PBR and its impact on older hardware, why the avatar count in the Destination Guide tend not to match the actual count in the region (because people can come and go quickly / time is required for the simulator to forward the information to the relevant service handling the DG and for it to be processed and displayed; updates to the DG are not real-time), and science fiction series (sorry, you had to be there).
