2026 week #28: SUG meeting summary

The Simulator User Group meeting place at Longfellow

The following notes were taken from the Tuesday, July 7, 2026 Simulator User Group (SUG) meeting. These notes form a summary of the items discussed, and are not intended to be a full transcript. They were taken from the video recording by Pantera, embedded at the end of this summary – my thanks to Pantera 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

  • No deployments for the week, just restarts
  • The next simulator update will be called Mango.

In Brief

  • Rider Linden:
    • Has merged in the rulebuilder code for Lua, so that’s ready to go. He noted that if any one wants to volunteer to fill out the tables for some functions it would be much appreciated.
    • This week he is on-call and hopes to hunt down an issue that’s causing some regions to fail to grant capabilities. He has ideas on the cause, and so is hopeful he can fix it.
    • Is also working on object publishing (prims as virtual filesystem that can be interacted with directly from VSCode, so it is possible to access and create scripts and notecards in a prim directly from VSCode rather than to have to keep switching focus between prims in world).
  • Leviathan Linden:
    • Is back working on game_control, currently doing an overhaul of the preferences UI and how the settings get formatted.
    • Notes the goal is to make it possible to map buttons to avatar movement actions (i.e. DPAD buttons to MOVE_FWD and MOVE_BACK)
    • Currently, the game_control viewer code is distinct from the Lua viewer code, but Leviathan plans on using that viewer in code merges with the game_control code.
  • Roxie Linden noted that:
    • Has been working on the WebRTC p2p IM bug where sessions fail to start, and is making progress. The issue seems to be a race condition in the back-end chat handling code; however, given the exact cause is hard to reproduce, there is no guarantee the fix in progress will correct all instances of session start failure, but Roxie optimistic.
    • On the viewer-side, has been working on changes to pull in a more recent libwebrtc + reduce some audio hiss.
  • Harold Linden (LUA):
    •  Has been busy with personal matters, but is now hoping to get back on top of  Lua PRs and resuming work on bringing the SL Lua back in-line with Luau upstream. This is seen as important as many things added to Luau upstream which would be useful for the Lua project (e.g. 64-bit integers and classes).
    • Commenting on the general state of the project, Harold added:
[the work is] Mainly polish at this point. I’d like our integer implementation to be based on Luau’s even if it’s not entirely the same under the hood so LSL can perform well, and I’d to have all scripts share a GC so that we don’t have separate memory allocators for each and every script as we do currently.
  • Monty Linden noted that lsl-definitions have been updated recently but not baked into a release and cycled around yet – this will happen “soonish”.

General Discussion

Please refer to the video below for  more on the following.

  • One of the issues with Lua on the simulator side has been the simulator crash rates. Rider described these as now being “encouraging”, many of the issues are “known and on the list to address”.
  • Harold’s comments on adopting upstream updates from Luau led to a discussion on 64-bit and 32-bit Lua support.
  • This in turn led to a discussion on Lua and llhttp.request.
  • A discussion on documentation.

Date of Next Meetings

  • Leviathan Linden: Tuesday, July 14, 2026.
  • Formal SUG meeting: Tuesday, July 21, 2026.

Kaleidoscape: a gorgeous vision in Second Life

Kaleidoscape, July 2026 – click any image for full size

Update, July 7th: Having had the chance to talk to 3chai4 concerning the greeter issue, she has indicated she will make adjustment at the first opportunity she has, but it is liable to take few days from the date of publication of this article.

Escape to Kaleidoscape, a peaceful medieval countryside filled with flower fields, working farms, hidden gardens, rustic taverns, and scenic walking trails. Whether you’re looking for photography, quiet exploration, or simply a place to relax, every corner offers a new story waiting to be discovered.

– Kaleidoscape Destination Guide description

Occupying a Full private region leveraging the additional Land Capacity bonus available to such regions, Kaleidoscape is the work of region holder 3chi4 (3chi4 Ethereal) with the help of Lisapia. And it is, in a word stunning.

Kaleidoscape, July 2026

Presented – as the Destination Guide entry notes – a medieval countryside, the setting has some interesting modern quirks within it which, as anachronistic as they might be when it comes to medieval times, collectively sit within the setting in a manner that gives it a unique twist without actually intruding into it to the point of distraction.

The most obvious of these is the live event stage tucked away in the south-east corner of the region. However, there are others – such as the mail boxes sitting outside of some of the houses, or the house numbers fixed to the walls of others and the occasional glimpse of overhead power lines together with electrical lighting indoors and out.

Kaleidoscape, July 2026

The Landing Point for the setting sits within a skybox. This is somewhat detached from the setting in theme given it is an alleyway from a modern Japanese city. From here, visitor click on the whirlpool on the ground to proceed on to the setting itself.

An annoyance here is a greeter script has been set-up at both ends of the teleport from Landing Point to ground. This repeatedly spams a greeting and a landmark to the region very other second – and does so every time the ground-level arrival point is passed. Given the arrival point has an information board with worthwhile reading and a horse rezzer for those wishing to ride around the region, this can get irritating.

Kaleidoscape, July 2026

Outside of this, however, the region design is genuinely breath-taking – and while there is a recommendation to use the local EEP settings, I would personally suggest switching to something brighter, as the region settings – in my opinion at least – cast things in far too much shadow, hiding a lot of the beauty of the region. To this end, I took the liberty of using one of my personal EEP daytime settings for the photographs seen in this article.

One of the useful items on the information board mentioned above is a map of the entire setting, outlining the main points of interest. This is also interactive: click on the name of a location on the map and you’ll be teleported to it. This is handy for those wishing to get to the events area or back to a specific place when resuming a visit. However, for first-time visitors I strongly recommend exploring on foot – or at least via one of the horses available from the rezzing stall alongside the information board.

Kaleidoscape, July 2026

The local village is probably the most obvious place to start such explorations. It certainly presents a lot of detail as it steps its way up a shoulder of land bounded on two sides by water on two sides by the cliffs of the region’s uplands to the south and west. It has an eclectic mix of buildings, most of which have an almost Tudor look to them; whilst one had a French lean and another – the water mill – carries a hint of hobbits about it.

Of the two bodies of water bounding the village, one might have once been an enclosed lake; however, two channels now connect it to the waters which separate the region from its mountainous surrounds. The second body of water, meanwhile, takes the form of a channel running inland from the west, cutting a gorge through the highlands before it narrows almost to the width of a stream to finds its way into the would-be lake, therefore placing the village on a rugged island.

Kaleidoscape, July 2026
The village – indeed, the setting as a whole – is populated by static NPCs, all of whom are most definitely in medieval garb. Ehile I think such characters can add personality to a location, they aren’t to everyone’s taste. This being the case, these NPCs have a special power: touch any of them and they will vanish to “go on a wander” around the setting, reappearing in due course. It’s a nice touch for those wishing to take photos but don’t wish to have NPCs in their frame & who don’t want to derender them.

The north side of the setting is beautifully pastoral in design, with sloping fields (two of them forming a marvellous sea of blue blooms with the occasional red and black flickering of butterfly wings) shared by two farms, one to the north-west of the landscape and stepping its way up into the hills there, and the other on lower-lying lands to the east.

Kaleidoscape, July 2026
Sheep, horses and cattle are to be found in the meadows to the east, the lake-like waters within easy reach for them when needing a drink, whilst a fence running between meadows and flower fields prevents them wandering too far.

Throughout all of this are multiple routes of exploration. Cart tracks connect the farms and their windmills with the village, bridges span the water channels and trails wind up into the hills.

Kaleidoscape, July 2026

The latter are home to the setting’s wildlife, and it’s worth keeping an eye out for the deer, foxes, stoats and so on which all help to bring more life to Kaleidoscape, as do the birds and ambient sounds throughout.

The degree of detail throughout is impressive: the houses of the village are all furnished, as are the farms houses and cabins to be found, cats keep an eye on things and there are multiple and various places for visitors to sit and pass the time.

Kaleidoscape, July 2026
I could write a while lot more here but really, Kaleidoscape deserves to be seen first-hand, so I recommend you go see for yourselves!
