2023 SL SUG meetings week #41 summary

The Waterfall Café, August 2023 –blog post †

The following notes were taken from the Tuesday, October 10th Simulator User Group (SUG) meeting. They form a summary of the items discussed, and is not intended to be a full transcript. A video of the entire meeting is embedded at the end of the article for those wishing to review the meeting in full – my thanks to Pantera for recording 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):
  • They 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.

Server Deployments

  • No deployments for the week. However, all simhosts (SLS Main and RC) will be restarted.

Upcoming Deployments

  • The initial work on updates to the SL damage system – specifically making damage a property of the object (e.g. a bullet), rather than being a script property (see the previous SUG meeting notes and this forum thread discussion) will now hopefully be available for testing on Aditi in week #42 and are being lined-up with the upcoming “Fall Colours” simulator update.
  • The rez_object_fail update planned for the upcoming “Fall Colours” simulator update is likely to slip back to a later simulator release.
  • The ability to turn an avatar invisible when they are sitting is being targeted for a simulator release following “Fall Colours”. This will help address issues such as allowing avatars to sit on small vehicles without them having to be deformed and folded up inside them to fit. This may additionally encompass the likes of feature requests BUG-232678 and/or BUG-233175.

Viewer Updates

No updates to viewers for the start of the week, leaving the official viewer pipelines as:

  • Release viewer, version 6.6.15.581961, promoted October 2 (formerly the Inventory Extensions Viewer).
  • Release channel cohorts:
  • Project viewers:

Potential for Games Controller Use

  • No major update, Leviathan is trapped in a loop of bug-hunting whilst trying to set-up a test region on Aditi with the necessary LSL support for controllers.

Region Crossing Code Tests

Monty Linden provided an initial breakdown on the recent region crossing code tests (see the two previous SUG meeting summaries). The summary being:

  • While chaotic and the resultant data not entirely reliable in all cases, it was sufficient to demonstrate the code tested can offer noticeable improvements to teleport and physical region crossings.
  • The tests specifically demonstrated that the impact of “bad” (script-heavy) attachments can be significantly reduced with the new code (up to around 5-6 faster in the very worst cases). That presumably relates to vehicle-related crossings more than anything, but hopefully Monty will clarify this once he gets to a stage of confidence in the data to perhaps provide a forum post).
  • Monty also commented that “bad” avatars (again for some undefined measure of “bad”) faired somewhat better during region crossings than he had anticipated.
  • More formalised testing method for crossings is being developed within the Lab, but Monty expects that the revised code thus far tested is likely to find its way into simulator releases in the future.

In Brief

  • Following the region crossing discussion, several people participating in the last pile-on test reported issues of attachments failing to re-load correctly following a teleport, and having to be manually re-attached. However, the same issue was also noted as occurring for some prior to the test, and also by some who didn’t attend the test, suggesting it may be an uptick in a pre-existing bug.
  • Rider Linden indicated he is considering implementing a fix to correct the following scenario:
An agent can select a physical object that they do not own and have no rights to edit and stop it in place. It is useful to be able to select the object, but causing it to stop interferes with events like racing. Somebody in the stands can grab the leader’s vehicle and hold it there.

This sparked a debate on the issue having been fixed with the implementation of llSetStatus(STATUS_BLOCK_GRAB_OBJECT) having already achieve this, together with suggestion to revise it (if it requires implementation) to exclude land owners, so they might continue to stop and move unwanted physical objects rezzed on their land by others. This discussion took-up most of the latter half of the meeting.

  • The end of the meeting includes a short discussion on revamping the Linden trees which focus on ideas and requests more than actual work being planned.
