2025 week #22: SL SUG meeting

Memories of Spring, March 2025 – blog post

The following notes were taken from the Tuesday, May 27th, 2025 Simulator User Group (SUG) meeting. They 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. No video this week.

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

  • There are no planned deployments to any channels this week, only restarts.
The team has been working on a lot of backend work getting things rebuilt for a more modern artifact management solution (think: rebuilding docker containers, libraries, etc.) –this is ongoing work. We also are doing more invisible work updating hardware to a newer configuration.

SL Viewer Updates

In Brief

  • A useful Feature Request: Log in Screen: “Region Offline” or “Region Restarting” warning prompt – vote!
  • A question on whether or not a viewer should expose the channel llDialog is operating on, or whether that is private information. Short answer: no it is not private; it’s in the viewer.
  • A debate as to how many regions run on a simulator and how many simulators run on a server, after a claim was made it is not 1:1:1.
    • Leviathan Linden: SL runs one Region per Simulator process. The actual Server (machine) runs multiple Simulators.
    • Monty Linden: the old 1/core vs 4/core is long gone – departed with uplift.
  • Confusion was voiced about region crossings and the idea that an avatar’s inventory is “handed over” between regions. This is not the case; only object inventory (scripts in your attachments) is transferred.
    • The confusion may have arisen by conflating issues of inventory size causing issues at log-in (which the Lab has been investigating) with the idea that the same is true for region crossings.
  • WebRTC “switch on” is still being held – currently because it still needs some bugs fixed; LL is looking to get the infrastructure sorted for a wider deployment across regions and is also looking at performance optimisations (as well as the issue of around 21% of Firestorm users not running a WebRTC capable version of that viewer).
  • A lot of general chit-chat about myths, frame rates, PBR and its impact on older hardware, why the avatar count in the Destination Guide tend not to match the actual count in the region (because people can come and go quickly / time is required for the simulator to forward the information to the relevant service handling the DG and for it to be processed and displayed; updates to the DG are not real-time), and science fiction series (sorry, you had to be there).

Caerleone Manor: a stately gem in Second Life

Caerleone Manor, May 2025 – click any image for full size
Dear Inara,
I’m writing to warmly invite you to visit Caerleone Manor, a recently completed destination in Second Life inspired by the elegance and cultural richness of 18th–19th century grand estates. The region features formal gardens, a grand ballroom, intimate salons, equestrian trails, and curated event spaces — all designed with immersive detail and historical ambiance in mind.

This was the opening to a personal invitation I received from Sethos Lionheart to visit his – frankly – stunning Full region design celebrating a bygone era of grand estates and magnificent homes. It was an invitation I was delighted to take up at the earliest opportunity for two reasons – beyond the extreme grace with which it was written, that is. The first being that I am a lover of what we in the UK call stately homes and thoroughly enjoy visiting them and appreciating their history. The second being that I have admired Sethos’ region designs, having written about them in the past – but to my shame, I’d actually lost track of his work.

Caerleone Manor, May 2025

As noted in the extract from Sethos’ invitation, Caerleone Manor (Lionheart(?) Manor) seeks to evoke the grand estates to be found across much of Europe in the 18th and 19th centuries (although its style perhaps suggests a strong French architectural influence). It’s not the first such region design to do so (perhaps the multi-region Angel Manor stands as the most famous example), but it is undoubtedly one of the best, and in being set within a single region, offers one of the most concise and visually engaging demonstrations of how a slice of physical and cultural history can be immersively brought into Second Life for the appreciation of many.

What is particularly impressive about Caerleone Manor is the fact that it brings together all the major aspects we find within a stately home held by a single family over several generations, all without ever feeling cramped or overcrowded. Building are all neatly spaced apart, giving lots of room for the gardens to breathe; the gardens themselves follow the familiar lines of such formal spaces, utilising geometry to present a sense of balance and harmony. Part of the estate  – notably the chapel and family burial area – given the estate a sense of established history; while the house itself speaks to potential generational occupancy – or at least, it plays host to a richness of family history.

In fact, this sense of familial history and the passage of time might be seen as existing within the buildings of the estate. Located to the rear of the main house, and elevated to offer a similar sense of command over the gardens, is the grand ballroom. It offers a different, and possibly later-era, architectural design compared to the house and its stables, suggesting it was built some time after them (the cocktail bar up on the gallery is certainly of a more recent vintage!). There is also an outdoor pool and terrace which might be a more recent addition to the estate.

The pool terrace offers one of a number of routes to a long ribbon of beach – passing by way of a magnificent folly. At the northern end of this beach is a further element which might conceivably been added well after the construction of the original house and outbuildings, in the form of an iron and stone (concrete?) pier with a distinctly late-Victorian lean. Such elements give a huge sense of the estate as a living entity, generations beyond the first placing their mark upon it in some way, large or small, living or sleeping within their burial houses.

While there is no grand approach to Caerleone Manor that is often in keeping with such great estates – the long drive being intended to focus the eye and awe of visitors on the grandeur of the house sitting at its end -, the house does offer grounds beyond the immediate buildings and gardens, again in keeping with such grand estates. These grounds can be explored by following the paved road that loops out from the carriage house to pass before the gates of the main estate (and the Landing Point) before then looping around the east side of the main estate and making a return. The road can be followed on foot or on horseback – a steed can be rezzed from the courtyard doors of the stables.

There is so much attention to detail outside of the main house that time should be spent exploring the paths and outer buildings; I particularly likes the two pavilions flanking the main garden and sitting between the main house and ballroom. The mottos inscribed over their entrances beautifully speak to life as they reveal the intended use.

Also within the grounds is a little kitchen farm, complete with hives for honey, chickens for eggs (and poultry for the table!), sheep (likely also destined for the dining table by way of the butcher’s cleaver) and a hutch of rabbits (which probably weren’t kept for petting by the children!). Also within the grounds is a feature oft found among grand homes: a hedge maze, this one offering those finding their way to its heart the opportunity for a dance – so taking a partner when following its paths are encouraged!

The House itself is beautifully furnished and rich in décor. The reception rooms and salons on the ground floor offer just the right mix of comfort and ostentatious design often found in these houses (take the monkeys holding up the room lights in the dining room!) without spilling over into gauche. The walls and ceilings feature beautiful panelling and decoration to give them a suitable Rococo sensibility.

The paintings and wall hangings all speak to the core period represented by the house, and more besides. In regard to the former, works by French artists Jean-Honoré Fragonard and François Boucher, together with pieces by Giovanni Paolo Panini – notably his Departure of the Duc de Choiseul from the Piazza di San Pietro (1754, and now displayed within the Staatliche Museen, Berlin) and View of the Campidoglio (1750) are to be found on walls. Meanwhile, carefully hung tapestries speak to much earlier periods, their presence suggestive of commemorating family history, whilst Auguste Bonheur adds a further Victorian era touch, although the precise time frame for the house’s presence to remain fluid within Sethos’ stated 18th-19th century intent.

As well as being historically relevant, I found the mixing of French and Italian artists, together with the statue of Napoleon Bonaparte to be found within the gardens as a reason for thinking the house is of French origin. Taken together,  they brought to mind Napoleon’s foray into Italy (1796/7) with its associated territorial gains for France, and which came just prior to his ascendancy to the position of Emperor (1799). However, this is my personal view, and not anything which may have been intended by Sethos; so take it with a grain or two of salt 🙂 .

Like stately homes in the modern era, Caerleone Manor does not only stand as a monumental to  bygone eras; it also hosts events and gatherings. These will commence on June 9th, 2025, with the Grand Opening of the house and its gardens estate, featuring the music of Jess Blues and an exhibition of  art by Hermes Kondor. Information on the Grand Opening and other forthcoming events can be found on the website accompanying the Manor. Meanwhile, the wrought iron conservatory in the ground appears is if it might be suitable for weddings.

With more to be discovered than I’ve covered here (including the opportunity to rest in the woods!), Caerleone Manor is a genuine delight and feast for the eyes of the detail-oriented. Or to put it another way: a must-see destination for Second Life explorers!
