2025 week #14: SL SUG meeting

Realm of Ihrydia, January 2025 – blog post

The following notes were taken from the Tuesday, April 1st, 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 and Pantera’s video, embedded at the end of this piece.

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 April 1st, the SLS Man Channel was updated with the Durian Scones update, which includes the SSL certificate renewal, making it grid-wide.
  • On Wednesday, April 2nd, the RC channels will be restarted without any deployment, other than a WebRTC update which will be deployed to the Preflight RC channel.

Planned Updates – LI Calculation Change (Recap)

  • Signal Linden highlighted a Feedback Ticket he has raised, proposing the removal of scale from Land Impact calculations.
  • This is being possibly earmarked for a simulator update after Durian Scones.
  • This essentially means that the LI of object should not dramatically change as a result of resizing (particularly when increased in size). It could also mean that some large objects in world could see LI reductions.
  • Understandably, this announcement led to a lot of discussion / debate throughout the meeting.
  • Signal also stated that the Lab will like – at some point also take a look at Mesh uploads and use: Incentivize correct use of LODs, which is currently being tracked.

SL Viewer Updates

  • Default viewer: 7.1.12.13550888671, formerly the ForeverFPS, dated March 1, 2025, promoted March 5th – No change.
    • Numerous crash and performance fixes.
    • Water exclusion surfaces.
    • Water improvements.
  • Second Life Release Candidate viewer 2025.03 version 7.1.13.14115832189, March 28th – NEW.
    • 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.
  • Second Life Project Lua Editor Alpha, version 7.1.12.13973830462, March 20th, 2025 – no change.

In Brief

Please refer to the the video for details on the following.

  • A request was made for linkset larger than the current 64m limit. This would have to be “thought about”, although it led to an extensive discussion on the idea (including issues of linkset visibility / draw distance / limits on older hardware).
Arbitrary link distances sounds like a neat idea, however I suspect such a change would only exacerbate some interest list bugs. I wonder what would happen if two 1cm^3 cubes were linked at 256m. The “position” of the linked object would be one of the prims. Its measure of “visibility” should be… what? The size of one or the size of the linked set?

– Leviathan Linden

  • The above led to a broad conversation on prim / object types, physics, prim torturing, etc.
  • Signal linden noted on the status of SLua:
Updates on SLua may slow down as we got a lot of good information from the alpha. We need to make some changes and prepare for a beta and production rollout.
  • Rider Linden also dropped a request into the meeting:
I’m looking for someone to write an extension. When I open a script file using VSCode check the current workspace. If it finds a file with the same base name, “link” the two files. 1) Copy the file from the workspace to the SL script temp file every time the WS file is saved.

Sheldon’s The Tyger in Second Life

The Tyger poster

I have a genuine love of poetry; be it Wordsworth, Shakespeare’s sonnets, Poe’s laments, T.S. Eliot’s journeys in verse, or evocative pieces from the likes of Masefield (Sea Fever) or  William Blake’s The Tyger.

Both of the latter are perhaps populist pieces; there are few, if any, lovers of poetry who cannot quote at least their opening lines. However, both contain a wealth of imagery and a depth of reflection on life – something often missed when reading either, such is the strength of the overlying imagery within them.

Of the two, Blake’s the Tyger is perhaps the more structurally and visually impressive, mixing as it does  trochaic tetrameter and  iambic tetrameter, alliteration and focused imagery, whilst also containing a deeper questioning which reaches beyond its own form, notably in reference to its “sister” (and potentially less well-known) piece The Lamb.

The Tyger is also the subject of a new poetic experience by the master of visual poetry in Second Life, Sheldon Bergman (SheldonBR).

I’ve covered Sheldon’s work in this pages, both in its own right, and with regards to his collaborations with Angelika Corrall, both as artists at and curators of, the former DaphneArts Gallery in Second Life. As such, I was delighted to receive a personal invitation from Sheldon to visit The Tyger, and took the first opportunity I could to immerse myself within it.

Now, when I say poetic experience with regards to Sheldon’s work, I mean just that; The Tyger is powered by a Second Life Experience, and it is essential you accept it on arrival at the installation if you are to proceed further, and then ensure your viewer is set as instructed in the pop-up (with the caveat that you only perhaps need to set Advanced Light Model (Preferences → Graphics) if you are running a non-PBR capable viewer and don’t run ALM as standard). Once you are set, click the Continue option on the HUD pop-up to deliver you to the installation proper.

The Tyger, Sheldon Bergman, April 2025

A quick point of none here is that your screen will go into a “letterbox” display format, courtesy of the HUD – and it is essential you should leave it in place. A second note here is that I’m not going to go into a deeply analytical piece on Blake’s works, by they The TygerThe Lamb, or the volumes from which they are drawn (Songs of Innocence and Songs of Experience), nor am I going to dwell overlong on Blake’s use of The Tyger as an exploration and questioning of 18th/19th century Christian religious paradigms. While these all fold into Sheldon’s The Tyger, they have all been written about extensively elsewhere.

Rather, what I will do here is offer thoughts on what appears to be a much broader canvas on which Sheldon paints, using The Tyger and its religious reflections as his foundation; a canvas which – to me at least – appears to offer thoughts not so much on our relationship with God, but our place within, and relationship as a whole with, the cosmos around us.

The installation initially begins within a twilight setting, at one end of a path formed by the waters of a stream rushing outwards from high waterfalls. The watery path is lit at intervals by pairs of candles, one to each bank. As well as lighting the way, they perhaps suggest the opening line of the poem and the flashes of colour one might see of a tiger passing through the shadows of the jungle. However, of more practical tone-setting (to my way of thinking, at least), is the initial quote offered by the HUD on arrival:

The clearest way into the Universe is through a forest wilderness.

– John Muir, environmentalist and philosopher

The Tyger, Sheldon Bergman, April 2025

This offers an intrinsic link between Sheldon’s use of the poem and its ability to question Christian tenets and paradigms with his broader theme as intuited above. One which grows as we follow the watery path as it travels through the gorge its has cut (symbolic, perhaps of the path we cut through life?) before the water turns to the left and enters a broad pool, and the visitor is left facing the open maw of a tunnel.

This opening, into which the flicking eyes of the candles lead us, is prefaced with a quote oft attributed to  Joseph Campbell (although so far as I’m aware is not something he wrote):

The cave you fear to enter holds the treasure you seek

It’s a statement that potentially takes us in several directions: caves can be thought of of dangerous and the home of predators; thus we remain rooted somewhat in the poem: whilst not a cave dweller itself, the tiger is perhaps the apex predator among land animals today. Further, caves can represent a journey into darkness and the unknown – just as life itself is a daily journey into the unknown; just as we have no idea what awaits at the end of our walk through the tunnel, we cannot comprehend what awaits at the end of our journey through life. Might it be the “treasure” of the kingdom of heaven as Christianity and its ilk would have us believe? Or might it be a quiet return to the nothingness of the Cosmos which, ultimately, birthed us?

Within Sheldon’s tunnel we have the opportunity to reflect both on Christian thinking – and the joining of Blake’s The Tyger with The Lamb  – complete with the opening lines of the latter (look for the side tunnel after passing the seaward opening in the tunnel walls). This is itself a layers element within the installation, encouraging us to consider Christian tenets (the Lamb of God, the Christian flock, etc.), whilst also underscoring Blake’s reflections on God’s apparently capricious nature as the creator of both the defenceless lamb and the deadly tiger:

When the stars threw down their spears,
And water’d heaven with their tears,
Did he smile his work to see?
Did he who made the Lamb make thee?
The Tyger, Sheldon Bergman, April 2025

It is also here – or at least, a little further down the tunnel – that the installation opens more fully onto questions of our place in the universe, starting with a further quote. This one from one of the great thinkers of the 20th century (and one of my heroes), Carl Sagan. It is a image he used a number of times in his writings, but it appears here in what is perhaps its most widely-quoted form:

The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.

Carl Sagan, Cosmos: A Personal Voyage: The Shores of the Cosmic Ocean (1980)

It is a quote that leads us, figuratively and literally, to a god’s-eye view of a spinning galaxy, a further marvellous metaphor and visual prompt for all that we might ascribe to Sheldon’s installation. It is also the perfect means to embody our unity with the universe, because to proceed, we must step through it.

The Tyger, Sheldon Bergman, April 2025

To do so is to enter the core of The Tyger, a space filled with the most incredible symbolism, questioning and statements for those willing to listen. From a vocal rendition of Blake’s poem, through the use of the Lacrimosa from Zbignew Preisner’s Requiem for My Friend (1998) to the lifting of the veil of blackness and revelation of Sheldon’s floating Tyger and its potential for layered interpretation, it is utterly breath-taking.

To itemise in words the richness and depth of all that’s offered here – from the poem, through the particular selection of Preisner’s Lacrimosa (hint: the piece has perhaps most memorably used to overlay the birth of the universe at the start if The Tree of Life, and we are perhaps particularly focused on the cosmos within this space) as well as its role within Zbignew’s Requiem (and indeed, the Catholic Requiem mass as a whole) to the presence of the floating Tyger and all that surrounds it – would be to defeat the purpose of the installation’s purpose.

Instead, I urge you to go and witness it; immerse yourself in The Tyger, its imagery, the richness of the poem itself and of Sheldon’s installation, and allow it to speak to you directly. It is magnificent.

The Tyger, Sheldon Bergman, April 2025
