2025 week #32: SL SUG meeting

Caerleone Manor, May 2025 – blog post

The following notes were taken from the Tuesday, August 5th, 2025 Simulator User Group (SUG) off-week meeting (which I’ll be referring to as the “SUG Leviathan Hour” going forward). These notes 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 and Patera’s video, which is embedded at the end of this article – 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 is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
  • The “SUG Leviathan Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
  • Meetings are held in text in-world, at this location.

Simulator Deployments

  • On Tuesday, August 5th, the majority of the grid – SLS Main channel and RC channels – was updated with simulator update 2025-07-25.16512260888.
  • The purpose behind this en masse restart (the first in a long time) was to account for network changes intended to allow the Lab to spread simhost servers across across multiple AWS availability zones (not necessarily AWS global regions).
  • As a result, there will be no RC channel restarts on Wednesday, August 6th.

AI Summit and Tools

  • Week #31 saw a Linden Lab summit on brainstorming how to use AI moving forward and experimenting with possible uses.
  • It is possible this summit may have caused the announcement on the forthcoming suspension / closure of the Character Generation project also made public during that week (see: LI announce a pause in the current SL AI character designer project).
  • As a result, Leviathan Linden has been exploring how hard it would be to use AI assistants to replace the llmath code in the viewer with GLM (graphics library math), a more standard and faster library; however, this is turning out to be more of a challenge than anticipated, with “lots of changes”, requiring care with the work.

SLua Update

  • Signal Linden defined the next goal for SLua is to roll it out to some Agni (Main grid) regions in a limited fashion. However there is work to be completed ahead of this happening – such as the project being made production ready, and “real” documentation assembled, and the inclusion of a new API for event handling.
  • Such a partial deployment would obviously be for testing purposes, and would mean that SLua scripts would only run on regions with the server-side support.
  • It was suggested that those regions offering building / scripting courses are considered for inclusion in Main grid SLua testing.
  • There is a concern that due to the amount of CPU time consumed even when idling, there is a concern that all script time in a region with a large number of SLua scripts could be consumed by idling scripts. This lead to a discussion on scripts, loads, scheduling and script times.

In Brief

  • As well as experimenting with GLM, Leviathan Linden has also trying to get some old server projects merged and shipped:
    • A slight speedup of scene load at login (and maybe less frequent missing content on arrival).
    • Compressed data from login.cgi for faster download of initial login data (and maybe fewer failed logins for people with lots of inventory folders).
  • Leviathan also hopes soon start working on the WebRTC voice streaming system.
  • Rider Linden is hoping to complete the LSL land functionality work he’s been developing for the Moles. This will include a llSetParcelForSale function (name still to be finalised at the time of writing).
  • Rider is also looking to expand llRequestInventoryData. There have already be requests for it to encompass to get information like tint and alpha from PBR textures, and sound and animation length.
    • Additional suggestions include PBR properties like metallic/roughness; animation priority; last attach point/position/rotation for a worn item, and last rezzed/in-world position/rotation.
  • Pepper Linden:
On the Conductor front, it’s been moving through QA, and we anticipate an Aditi and Agni rollout within the next week. During the initial roll out, we’ll be keeping the packing mode the same, and later on, turning on our new ‘packing’ logic (how we place regions on servers).
Some minor notes on our Discord integration for community servers, I had promised that we’d get that out relatively soon but unfortunately Discord has rolled out a UI change to profiles that’s now hiding the connection details, so that’s something we’ll need to figure out and handle before releasing it.
  • Monty Linden is finishing-up work to move the experience KVP store.
  • Signal Linden has been working on multiple projects:
    • Putting together release plans for the next viewer release.
    • Coordinating with contributors on viewer Discord integration, apple silicon support and other projects.
    • Following up on the August 5th deployment, and preparing to put some simhosts into another AWS availability zone.
  • As noted in my week #31 TPVD meeting notes, Camera Constraints Bug (below -0 metre altitude) has been filed. This affects all v7 viewers – but Kirsten Lee (Kirsten’s Viewer) has filed a possible fix.
  • The mention of the llSetParcelForSale function resulted in a discussion on land rentals in the second half of the meeting – specifically around the use of texture  / signs at altitude advertising regions / parcel available for rent, when looking at the world map.

Date of Next Meetings

  • Formal SUG meeting: Tuesday, August 19th, 2025.
  • Leviathan Linden: Tuesday, August 26th, 2025.

Purple Moon Ashes in Second Life

Purple Moon Ashes, August 2025 – click and image for full size

Purple Moon Ashes is a Full private region developed as a public space encompassing fantasy and magic, designed by Elguaje70 and DjDDB. It drew my attention after I noted it in the Destination Guide due to the use of items created by Elicio Ember, whom regulars to the pages will know, is both a close friend and a creator of elven-themed designs I never fail to find gorgeously attractive.

Surrounded by off-region hills, Purple Moon Ashes is a setting which becomes increasingly more attractive the longer one spends time within it – although I would note that the Shared Environment available at the time of my visit differed substantially from the EEP settings used in the Destination Guide entry for the region and – in my personal option – didn’t display the region at its best. This being the case, and after a little experimentation, I opted to use one of my personal “fallback” EEP settings for the photographs shown here.

Purple Moon Ashes, August 2025
It is a pleasure to invite you to explore this wonderful Purple Moon Ashes, a place where magic lives from the first moment you arrive; enjoy the dragon ride and the gondola ride. Come and discover how much more magic you can experience.

– Purple Moon Ashes About Land Description

The core of the region comprises a circular lake dominated by a central water / ruins feature which includes two large stone water serpents gushing water from their mouths. Three circular dance floors extend out over the lake from the surrounding largely circular, land enclosing the waters. Each of these platforms is placed roughly equidistantly around the circumference of the lake and each offers two points of access to the shallow waters, allowing visitors to walk to the central feature if they so wish.

Outside the lake, the land surrounding it offers multiple points of interest, all neatly linked by footpaths and flower trails.  The Landing Point sits on a plateau on the north-west quadrant of the region and is home to one of the teleport boards offering quick links to the major locations within the region (although I recommend using your pedal extremities to explore!) and the dragon ride mentioned in the About Land description. It also hides the region’s secrets below it – but I’ll leave it to you to discover the way into them 🙂 .

There are two ways down from the top of the plateau, each utilising elements created by Elicio. One runs gently down to the western side of the region, before a glass footpath directs explorers south and then east, where it is possible to climb the long finger of a rising promontory, which itself turns back to the north as it comes to the eastern side of the setting.

The second way down from the plateau is on its north side, passing by way of a large dance area build atop a smaller plateau of rock rising from the sea. Steps from here descend to join another glass path lain among the wildflowers as it travels eastwards to reach a large domed pavilion at it furthest extent, and beyond which the trail becomes one of grass and flowers.

It is this second route down from the plateau which offers one of the opportunities to take one of the region’s gondola tours (just to the left of the raise walkway from the last set if steps descending from the plateau). These tours are point-to-point, and so also allow visitors to reach specific destinations within the region. Boats are suitable for singles or couples, and sitting in a gondola will display a dialogue box of the destinations available from each embarkation point.

As each tour ends at the embarkation point for another, it is possible to use them in sequence to view the region, hopping from one boat to the next at each stop. It is via these gondolas that the narrow spit of land running along the north side of the region is best reached (“Forest Love”).

There is a good degree of repetition across the region in terms of statues and architecture – unicorns large and small, benches with statues, winged fairies spouting water, Elicio’s elven arches and glass walkways, stone gazebos with giant daisy-like places to sit within them, etc. These all work thematically and act as motifs for the region, offering opportunities for the imagination to invent suitable backstories for the setting.

Also to be found through the setting are multiple places to dance, including couples poseballs tucked away here and there as well as the more familiar dance systems hanging in the air over the more obvious dance locations. From the advertising I caught during my visit, I gather the region is also home to live music events. Details of these, I assume, are available through the local Group – but it appears this requires contacting either Elguaje70 or DjDDB in order to join.

With places to sit scattered throughout (including about the sail vessel and within the aforementioned caves), Purple Moon Ashes provides multiple reasons to not only explore, but also to relax and unwind within its borders. The local sounds are not intrusive, and the setting lends itself to a wide variety of EEP options.

In all, a visually engaging and charming visit.
