2025 week #19: SL SUG meeting

Buddha Garden, February 2025 – blog post

The following notes were taken from the Tuesday, May 6th, 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 my chat log of the meeting. Pantera also recorded the meeting, and that recording is embedded at the end of this piece – my thanks to Pantera, as always, 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):
  • 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, May 6th, the Main SLS channel was restarted without any update.
  • On Wednesday, May 7th:
    • BlueSteel and the snack channel running the Elderberry simulator update (see below) should be restarted.
    •  All remaining RC channels should be updated with Elderberry.

Elderberry Update (2025.05)

  • A new option to llDerezObject – DEREZ_TO_INVENTORY, which returns the targeted object to inventory and saves its current state (e.g. has the same behaviour as Build → Object → Save Back to Object Contents.
  • llIsLinkGLTFMaterial  – which can can determine if a face on a linked prim is PBR.
  • REZFLAG_DIE_ON_NO_REZZER – which will cause a rezzed prim to die if its rezzer is no longer present in the region.
  • llSetGLTFOverrides, rather than changes to llSetColor and llSetAlpha to work with PBR, as changing the latter was “starting to lead down some very scary paths WRT ‘What is the right thing to do'”.
  • Possibly a fix for llSetGroundTexture, which currently has the NE & SW values swapped. The question was asked in this was in the release, but the question wasn’t fully answered.

Upcoming Deployment – Fig Pudding (2025.06)

  • This is still being put together.
  • The update is unlikely to surface before June, as the simulator team has been focusing on some necessary internal work (e.g. ensuring various repositories build and deploy via Github actions correctly; updating where docker images are stored) which has drawn attention away from feature work on the simulators.

SL Viewer Updates

  •  Default viewer: 2025.03 7.1.13.14343205944, issued April 9th and promoted April 15th.
    • New UI element for water exclusion surfaces: Build / Edit floater → Texture Tab → Hide Water checkbox.
    • The maximum amount of Reflection Probes can now be adjusted to better accommodate low VRAM scenarios.
      • Values will be set automatically depending on your chosen graphics quality. OR
      • Use Preferences → Graphics →  Advanced Settings →  Max. Reflection Probes to manually set.
    • An issue with being unable to see Sky Altitude values in the Region/Estate window has now been resolved.
    • Preferences → Graphics → Max. # of Non-Imposters has been renamed Max. # of Animated Avatars for clarity.
    • Bug and performance fixes and memory optimisations.
  • Release Candidate: 2025.04 – 7.1.14.14742193597, May 2nd 2025 – NEW.
    • Includes the following new features:
      • Chat Mentions (Early Support): Type @ then pick a name. To follow: audible alerts and highlight colour pickers.
      • My Outfits subfolders: now supports the use of subfolders.
    • Key updates:
      • Build Floater improvements: increase to scale boundaries; Physics Material Type now updates when selecting linked objects; Repeats per Meter value no longer incorrect for non-uniform sized objects
      • Hover height: the minimum/maximum is now +/- 3 meters.
      • Snapshot floater: L$ balances can be hidden independently of the rest of the UI.
      • Preference Search bar: general usability and readability improvements.
    • Refer to the release notes for full updates and fixes.
  • Second Life Project Lua Editor Alpha, version 7.1.12.14175675593, April 2nd.

In Brief

  • A request for SLua events to be updated along the lines suggested in this canny request. Rider Linden indicated that a update will be made prior to SLua moving to wider beta testing, and will likely It will likely end up looking similar to the Canny proposal. However, there is no current time frame as to when the update will be made.
  • A Canny request was filed in January for a llGetRegionWorldMapTile feature. This was reportedly now sitting in the backlog of requests and work the server team are hoping to work through in time.
    • This saw a follow-up request at the meeting to be able to zoom down to the level of centring a parcel on the map. Rider indicated that it should be possible to give the full region map as a as a texture ID, allowing scripts to adjust the offset and scale of the texture to achieve desired results.
  • A discussion on regions idling (at 1 FPS(?)) when not in use (e.g. when there are no avatars in the region, no child agents registered with in and no HTTP IN/OUT functions running); the ability for llGetEnv to obtain a region’s status.
    • Regions are not completely shut-down when “empty”. as most require scripts to keep running.
    • This broadened into a discussion on how low a region takes to start-up. The most accurate might be “no long in the scheme of things, but variable”.
  • In response to a question on progress with combat 2.1 features, Rider stated:
Combat 2.1 is pushed back. I’ve got no eta when that will come back up. I’d like to get it moving, I think it introduces some important additions that have impacts outside of just Combat, but there are lots of things that need doing and I can only type so fast.
  • The latter half of the meeting was taken up with discussions of texture loading, the impact of alpha layering, non-optimised contents and similar, the majority of which was more viewer-centric. They arose from a complaint that Fantasy Faire is overloaded with “4K textures” (which aren’t actually a thing in SL) causing viewer performance issues.

Ythari – The echo of silent stars in Second Life

Ythari – Echoes of the Silent Stars, May 2025 – click any image for full size
For May – the start of which has become somewhat indelibly linked with science fiction over the last several decades – Saskia Rieko and Konrad (kaiju.kohime) bring us their own epic sci-fi tale; one with its roots in a galaxy-spanning civilisation called the Ythari.

Born long before most others, the Ythari were driven by their insatiable intellects, boundless ambition and an overbearing pride and arrogance which perhaps led to their downfall.

The Ythari once ruled over a vast and enigmatic galaxy known as Veilspire — a name derived from its most haunting feature: a towering, luminous rift that cuts across its heart, like a tear in the fabric of space-time. This anomaly called the Axiom Rift, existing in the very centre of the galaxy, is believed to be the result of their final and most ambitious experiment — perhaps even the very thing that led to their disappearance.

– from the records of Dr. Khiraan Valis

Ythari – Echoes of the Silent Stars, May 2025

Konrad and Saskia have always produced richly engaging settings within Second Life, often drawing on inspiration from locations and event on or from our physical world. Ythari – Echoes of the Silent Stars, however is utterly different in theme and tone – although its depth easily equals that of any of the previous designs the couple have presented. Whilst it might not draw from events and locations we might all directly research, instead being born entirely of the imagination, it nevertheless comes with a rich back-story; one capable of forming the basis of a novel from the likes or Asimov, Heinlein or James S. A. Corey (aka Daniel Abraham and Ty Franck) for an entire novel.

Mixing a thirst for knowledge and a hunger for understanding with towering abilities and intelligence, the story of the Ythari is one of a galaxy-spanning empire built not on war or dominion, but on the foundations of science, intellect, and an ability to conceive everything within their galaxy from the quantum level to the macro, without any apparent discontinuities of scale.

Ythari – Echoes of the Silent Stars, May 2025
Veilspire was no ordinary galaxy. Unlike the spiral and elliptical galaxies known to modern astronomers, its structure bore evidence of deliberate engineering. Star systems arranged in mathematically perfect formations, gravity-defying megastructures orbiting black holes with impossible stability, and entire regions where time seemed to flow at inconsistent rates, with the centre of the creation, The Axiom Rift — all hints that the Ythari did not merely live in their galaxy, they designed it with the development of The Equation of Being.

– from the records of Dr. Khiraan Valis

It is also a tale of galactic overreach and a hubris which – perhaps inevitably – could only result in one of two outcomes. Outcomes which themselves might perhaps be indistinguishable from one another, thanks to the passage of aeons and when looked upon through the eyes of a far-future humanoid race stumbling across the crumbling, but still magnificent relics the Ythari left in their wake.

Ythari – Echoes of the Silent Stars, May 2025
As they neared the completion of their greatest project — an attempt to rewrite the fundamental laws of reality — they miscalculated. Or perhaps they succeeded too well. One by one, their great cities, planets, even the whole solar systems fell silent … The Ythari simply… ceased. Their towering spires, their quantum archives left behind as if abandoned in an instant. No bodies. No signs of struggle. Only silence and the mysterious humming of the abandoned Axiom Rift.

– from the records of Dr. Khiraan Valis

To best appreciate the setting, make sure you have your viewer set the Use Shared Environment, and you have media set to play (at least initially in the case of the latter). The arrival point will provide you with the back-story in the form of a records / log entry by one Dr. Khiraan Valis, an archaeologist dedicated to uncovering the mysteries of the Ythari.

The latter is played back over the computer screens and consoles at the landing Point, and really is worth listening to. For those who prefer, the same information can be obtained by clicking the traditional Natthimmel greeting (and setting name) on the ground of the Landing Point, and accepting the offered folder. This contains a notecard with the  information given within the narration. For those who do listen to the audio, I would strongly suggest pausing media playback (click the movie camera icon / button towards the top right corner of the viewer’s window), as the narrative track can otherwise overwhelm the ambient sounds within the setting.

Ythari – Echoes of the Silent Stars, May 2025

Stormy, eerie and caught under a roiling, almost angry Expanse in which the eye of a galactic core balefully stares from one horizon, this is an environment for which words – genuinely – are not enough. Beyond the consoles and systems at the Landing Point, as left by Dr. Valis and her team, this is an assuredly alien setting. Within it, a water-like sea slips into a low-lying landscape. This initially appears to be dotted with strange tree-like groves. However, closer inspection reveals them to be more rock-like than organic – or perhaps they are the fossilised remains of something; and while there is the odd tree to be found, organics as we might recognise them are few and far between.

Even the paths laid across the water have a geometry about them that feels alien. None lead directly from A to B; instead they seem to be some kind of mathematical expression, as much a part of the gigantic towers and other structures within and floating over these strange lands.

Ythari – Echoes of the Silent Stars, May 2025

Broken, decaying, and ominous even when countered but the roiling heavens beyond them, these structures are riven by massive discharges of energy, themselves accompanied by rolling booms which fall upon the ears as the funerial beat of drums. Whether these discharges are is being generated by whatever remain powers keep at least some of these artefacts raised in defiance of gravity, or whether the explosions of light and energy are the angry response of the atmosphere to their hulking presence, is yours to determine.

Not all the structures are airborne or massive; floating on the waters are polygonal forms, cables and relays on them looking as if they might have once drawn power from the waters – or discharged it into the waver over which they sit. They sit around the remnants of the great towers as if part of their ancient function. Steps climb the interiors of the towers, while outside of one is an indication that the Ythari might not have vanished completely.

Ythari – Echoes of the Silent Stars, May 2025

The very few who dare to explore their ruins tell of anomalies time fractures where the past leaks through, machines that seem to remember their creators, and strange, whispering voices that seem to come from nowhere. The Ythari may be gone, but something of them lingers. Watching. Waiting.

Beautiful, visually impressive, rich in narrative and creativity, edged in mystery and a hint of dread, Ythari – Echoes of the Silent Stars is a magnificent journey of the imagination.
