Sophie’s Infernal Symbiosis and Yellow Impressions in Second Life

Subcutan Art Gallery, February 2026: Sophie de Saint Phalle – Infernal Symbiosis

Sophie de Saint Phalle (Perpetua1010) has recently opened two exhibitions of her work, each of which is also set to words offering both insight and description.

The first, which opened on February 13th at Sophie’s own Subcutan Art Gallery, where it occupies an atmospheric skybox exhibition space. It is entitled Infernal Symbiosis, and perhaps the best way to describe it is a celebration of the meeting of self and nature, and the ability of the latter to remove the noise, the insistent pressure the demons of modern life, and to remind us of our heritage and our being a part of Nature and the world around use.

Subcutan Art Gallery, February 2026: Sophie de Saint Phalle – Infernal Symbiosis
The watercolours were created at the edge of flow— in the forest, beside a narrow creek. Water becomes body; body becomes landscape. Nature and human dissolve their borders and remember their shared origin.

– Sophie de Saint Phalle, Internal Symbiosis

In the darkness of the gallery space, the vibrancy of the 14 abstract paintings is perfectly brought to life, the fluid lines and flowing colours giving a sense of both motion to what are essentially still life images, together with a sense of water-like fluidity. Together  they give us a beautiful sense of harmonious intermingling of our humanity and Nature.

Subcutan Art Gallery, February 2026: Sophie de Saint Phalle – Infernal Symbiosis

In this, it is – to me at least – vital to take in the ambience of the gallery space as a whole; within Subcutan, Sophie always takes care to offer her art in terms of an immersive environment, where setting, art and EEP all combine to form an experience to be explored and appreciated. This is very much the case here, the outer lobby of the main hall and the scenes visible through the windows adding creative depth and feeling to the exhibition as a whole.

Sophie’s second current – at the time of writing – exhibition opened on February 19th at ArtCare Gallery, curated and operated by Carelyna. Again occupying a sky-base exhibition space is Yellow Impressions.

ArtCare Gallery, February 2026: Sophie de Saint Phalle – Yellow Impressions

It offers some 13 nude images presented as marble etchings, all of which carry a similar theme of symbiosis and joining – or perhaps understanding might be a better term, as Sophie notes in the text accompanying the exhibition.

As myself became intertwined with the soul structures of others, surface turned into tangible life. In this transition — between inner perception and outward appearance —an image-skin emerges that does not depict, but carries.

– Sophie de Saint Phalle, Yellow Impressions

ArtCare Gallery, February 2026: Sophie de Saint Phalle – Yellow Impressions

That the nudes are what might be termed partial studies – and indeed possibly familiar to followers of Sophie’s work – matters not. Again, as Sophie notes, reduction of the body, the absence of features (e.g. head, or facial features) and focus on specific elements of the human body (e.g. the torso),becomes a method of approach, a means to express the idea of both self and our perception of others becoming intertwined; an energy flow if you will, of a subconscious yet perceptual openness – or perhaps offering – of one to another.

Taken together or individually, Infernal Symbiosis and Yellow Expressions are both shirking and visually engaging, whilst the words accompanying them (touch the exhibition title boards in each case to receive these), allow us to thread the path of the deeper expression and meaning within both.

Highly recommended.

2026 week #8: SUG meeting summary

Sable Hound Hollow – Romantic Reverie, January 2026 – blog post

The following notes were taken from the Tuesday, February 17th, 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

  • Tuesday, February 17th, 2026:  the SLS Main channel simhosts were restarted and updated to simulator release 2026.02 (Kiwi). This includes:
    • LL’s annual server certification changes – some outstanding changes are required to Aditi (the Beta grid), Agni is fully up-to-date.
    • “PERMISSION_PRIVILEGED_LAND_ACCESS”, allowing the llSetParcelForSale function to be used (and potentially other parcel settings in the future), but will require a viewer-side update in order to be accessed.
    • A bug fix to llTransferOwnership that was stripping out items that it shouldn’t have.
  • On Wednesday February 18th, all simhosts on the RC channels should be restarted without any updates.
  • The next simulator release is now officially 2026.03 – Loganberry; no details are currently unavailable.

In Brief

Please also refer to the video, below.

  • Rider Linden is currently engaged on some under the hood backlog fixes that have been needed for quite a while.
  • Rider also raised two “how much will this break?” questions:
    • Right now LL’s LSL Regex operates on 8 bit characters. A bug report has been submitted about it not supporting unicode. So the question is: what if LL switched to using unicode under the hood. Another option on that would be to add a flag at the end (like “/i”) that would indicate it should unicode? The favour shown at the meeting was an under-the-hood unicode change although concerns was raised over the potential for implement work-arounds to the issue which might be in widespread use.
    • The second question was on change notification on texture changes – and the fact that LL aren’t sending them; the notifications are available on a scripted texture change, but are not being fired. This discussion got mixed in with  discussion on “Second Life II” (which Sansar sort-of wasn’t, although also kind-of was) please refer to the latter half of the meeting for details.
  • Leviathan Linden:
    • Is working on “some final changes to my workaround for the “cannot change mesh face” problem. After code review some changes were determined to be necessary.
    • He has also implemented a submission from Henri Beauchamp (Cool VL Viewer) to try to resolve the issue of “perpetually cloudy avatars” by resending avatar attachment info whenever the viewer requests avatar textures. This still requires further refinement and addition to a simulator update, but it is progressing.
    • A bug report about too many listen events when creating similar llListen() filters; this is now seen as a bug and a fix from Leviathan will be a part of 2026.03 Loganberry.
    • Leviathan has also received a bug report against the game-control viewer pre-release: custom key (button?) mappings are not being saved. He has not as yet been able to dig into it, but wanted people to know it is on his radar.
  • Harold Linden (SLua):
    • Has added a couple of things: `table.append()` and `table.extend()` so that it’s much less annoying to work with lists of rules as is typical in existing functions like set primitive params/. This will be deployed in an upcoming TBD simulator update, as it still needs a couple of “tweaks”.
    • Harold is also working on a fix for `string.gsub()` and `table.sort()` and friends killing your script if they run too long.
    • Various questions throughout the meeting on SLua – please refer to the video.
  • SLua Resources (as it was asked during the meeting):
    • Official scripting portal (this is a work in progress and open to contributions – Github for the latter here).
    • The Second Life official Discord server / channels.
    •  Suzanna’s SLua Guide (Suzanna  Linn).
    • Official VScode plugin notes:
      • It is not yet available on the VScode marketplace.
      • Issues and PRs for code submissions can be made here, and the plugin downloaded.
    • VSCode plugin + documentation (Wolfgang Senizen – likely be discontinued and contributions shifted to support the official documentation).
  • The subject of region crossings causing issues and the need for them to be a “top priority” for “fixes”.
    • Harold Linden has done some work on some work to improve the testing situation there. Now that LL has codified how it (mis)behaves, he hopes LL can define a path for the correct behaviour while ensuring fixes don’t break existing viewers that rely on the broken behaviour
  • Roxie Linden repeated her update that WebRTC is tentatively targeting a March deployment for WebRTC. When it happens, it will be a typical server rollout (week one: limited simulator RC channel deployment; week 2: deployment to all remaining simulator RC channels; week three deployment to the rest of Agni). However, if anything comes up, one or more stages of deployment may be delayed for fixes.
  • Another viewer side-track for a server meeting, this time questioning the arrived of the “visual polish” viewer with SSR updates, something covered at the Content Creation User Group (attended by the individual raising the question at this meeting).
  • I had to depart the meeting early; please refer to Pantera’s video (blow) for the final 20 minutes.

Date of Next Meetings

  • Leviathan Linden: Tuesday, February 24th, 2026.
  • Formal SUG meeting: Tuesday, March 3rd, 2026.

Stevie’s Sanctuary in Second Life

Stevie Basevi’s Sanctuary, February 2026 – click any image for full size

Earlier in February, Honey Heart (H0neyHeart) – whose Sable Hound Hollow I visited towards the end of January 2026 –  dropped me a line to let me know our mutual friend / acquaintance, Stevie Morane Basevi (Stevie Basevi) would be officially re-opening her region of Sanctuary on February 19th, although it is already available for people to drop in an explore, together with the neighbouring region of Zantosa.

Stevie is something of a tour de force in Second Life. I first met her through Relay for Life of Second Life, before coming to know her a little more through both her art and her association with projects I’ve tended to follow and support in my own way: One Billion Rising, The Dickens Project and the Bradbury Project. An avid role-player, Stevie first established Sanctuary in 2008, growing it over time to a community and location covering many aspects of Second Life.

Stevie Basevi’s Sanctuary, February 2026
Sanctuary, long celebrated for its award-winning historical role-play, has evolved into a vibrant cultural space for art, photography, dance, music, and theatre—welcoming global gatherings and creativity without borders.

– Sanctuary About Land Description

For this latest iteration, both Sanctuary and Zantosa – each of which are Full private regions leveraging the Land Capacity bonus available to such regions – Stevie has turned to another old acquaintance to design the overall look and layout of the regions: Busta  (Busta Blakewell, previously badboyhi, whose regions designs have regularly featured throughout this blog.

Stevie Basevi’s Sanctuary, February 2026

Given the size of both regions, I’m not going to try to cover them both in a single post; they are richly laid out and offer much to be discovered, so will hopefully return to Zantosa at some point in the near future.

Sanctuary offers a setting suggestive of somewhere in England; a place with certain timelessness – parts of it could easily be Victorian, others carry a faint hint of the 1950s-1960.

Stevie Basevi’s Sanctuary, February 2026

This town is the kind of place in which it would come as no surprise to turn a corner and find Sherlock Holmes lecturing Dr. John Watson on the minutiae of various powdering of ash and a certain bird droppings will inevitably lead to the cornering of their quarry. Turn another and it would be equally unsurprising to witness find a dapper John Steed stepping down from the running board of his 1930 Bentley Speed Six, umbrella in hand as he rounds the front of the car to open the door to allow Ms. Emma Peel to gracefully alight.

In other words, it is immediately immersive and open to broad role-play opportunities.

Stevie Basevi’s Sanctuary, February 2026

The Landing Point sits to the east side of the region and within the town square. Splitting the townscape in two is a high wall and a tall gatehouse. The latter forms a teleport link to the neighbouring Zantosa. Simply walk towards the gates to be teleported across the region boundary.

The local lunatic asylum offers its own opportunity for potential role-play, having been turned into a bar – although who is to say some of the former residents aren’t lurking in the upper floors? The asylum is one of a number of locations within the town which can be explored. Others include the local church, a pair of pavilions offering a kind of two-part music conservatory, the theatre  and the Sanctuary art gallery, featuring Stevie’s art on the ground floor.

Stevie Basevi’s Sanctuary, February 2026

It is outside the church that visitors can obtain further information on the region, including a delightful back-story to its development and a teleport HUD to help reach points of interest – simply add it from inventory to use it.

The majority of the locations on the teleport HUD can be found on the ground level of the setting and so can be reached on foot. Two, however, are sky-based and will require the HUD to reach them.

Stevie Basevi’s Sanctuary, February 2026

I’m not going to give a blow-by-blow description of the region, it really does speak for itself in terms of design, atmosphere and details. I will however note that there is a further art display – dedicated to Sue Elaine Winkler to the rear of the main gallery building.

Part of the region is cut through with a storm drain linking two low-lying parts of the setting. This carries a suggestion a degree of land reclamation has taken place, resulting in an inland body of water complete with multiple places to sit and appreciate the setting, together with a recovered area of coastline forming both a walk and further places to sit and pass the time.

Stevie Basevi’s Sanctuary, February 2026

Whether or not you are into role-play, structured or casual, sanctuary makes for an engaging and photogenic visit.

Space Sunday: lunar ambitions: the real and the not-so-real

The current “race for the Moon” is turning into a hare-and-tortoise situation on several levels, including internationally. On the one hand, there is America’s (arguably over-complicated, thanks to NASA’s insistence on the use of cryogenic propulsion to get to / from the lunar surface) Artemis programme, which seems to race along in fits and bursts (and frequently slams itself into a wall of delay) and then there is China’s more conservative “latter-day Apollo” approach, which quietly plods along, racking up achievements and milestones whilst seeming to be technologically far behind US-led efforts.

As noted, China’s approach to reaching the Moon, is something of a harkening back to the days of Apollo in that it uses a relatively small-scale crewed vehicle for getting between Earth and the Moon, and a similarly small-scale lander. However, size isn’t everything, and both crew vehicle and lander (the latter of which has a cargo variant) would be more than capable in allowing China to establish a modest human presence on the Moon, just as their Tiangong space station, whilst barely 1/4 the size of the International Space Station, has allowed them to do the same in Earth orbit. It is also important to recognise it as part of an integrated, step-by-step lunar programme officially called the Chinese Lunar Exploration Programme (CLEP) and familiarly referenced as the Chang’e Project after the Chinese Goddess of the Moon, which has allowed China to develop both a greater understanding of operations on the Moon and in understanding the Moon itself.

The Chang’e project commenced over 20 years ago, and recorded its first successes in 2007 and 2010 with its Phase 1 orbital robotic missions. This was followed by the Phase II lander / rover missions (Chang’e 3 and Chang’e 4) in 2013 and 2018 respectively, and then the Phase III sample return mission of Chang’e 5 (2020).

Currently, the programme is in its fourth phase, an extensive study of the South Polar Region of the Moon in preparation for human landings, nominally targeting 2030. This phase of the programme has already seen the highly successful Chang’e 6 mission, the first to retrieve surface samples from the Moon’s far side, as well as deploying a rover there. 2026 will see Chang’e 7 launched, a high concept resource seeking mission comprising an orbiter, lander and “lunar flyer”, all geared to locate resources which can be utilised by future missions.

China’s Chang’e 6 mission, launched in May 2024, was the first Chinese mission to the far side of the Moon, and the first mission to ever return samples gathered from the lunar far side and return them to Earth (June 2024). In this image, Chang’e 6 is seen from the Jinchan mini-rover, which piggybacked a ride to the Moon with the lander. Credit: CNSA.

In 2028, the last of the Phase IV mission will launch. Chang’e 8 is intended to be a combination of in-situ resource utilisation (ISRU) test bed, demonstrating how local materials (water ice, regolith) can be used to produce structures on the Moon via advanced 3D printing, and to establish a small ecosystem experiment in advance of human landings.

This approach means that from a standing start, China has replicated much of NASA’s work of the 1960s that helped pave the way for Apollo, but in much greater depth. It’s not unfair to say that by retuning such a focused series of mission phases – notably Phase IV – China potentially will develop a greater spread of knowledge concerning the Moon’s South Polar Region than NASA.

At the same time, China has been developing the hardware required for the human side of the Chang’e Project. This primarily takes the form of their Mengzhou (“Dream Vessel”) reusable crewed vehicle, the Lanyue (“Embracing the Moon”) 2-stage lunar  lander / ascent vehicle and the Long March 10 semi-reusable heavy lift launch vehicle (HLLV) offering a very similar capability to Blue Origin’s New Glenn vehicle.

Mengzhou is being developed in two variants: a low Earth orbit (LEO) variant, designed to ferry crews to / from the Tiangong space station. The second is being developed expressly for lunar missions, offering an increased mission endurance capability. The first uncrewed orbital test-flight for the 14-tonne LEO version of Mengzhou is due to take place in 2026, the system having been going through progressive flight tests throughout the 2010 and early 2020s. If successful, it will pave the way for the vehicle to start operating on crewed flights to Tiangong alongside the current Shenzhou craft, which it will eventually replace.

Launch of the CZ-10A and Mengzhou test vehicles, February 11th, 2026. Credit: CCTV

On February 11th, 2026, a test article of the 21-tonne Mengzhou lunar vehicle completed a significant test atop the core reusable stage Long March 10 (Chinese designation CZ-10A) booster. This was a combined mission to test both the Mengzhou launch abort system (LAS) whilst under the rocket’s maximum dynamical pressure flight-regime, and also the booster’s ability to complete an ascent to its nominal stage separation altitude of 105 km, and then make a controlled descent and splashdown close to its recovery ship.

Following a successful launch, the combined vehicle climbed up to the period of “Max Q”, around 1 minute into a flight and wherein the maximum dynamic forces are being applied to the entire stack. The Mengzhou LAS successfully triggered, boosting the vehicle away from the Long March core stage at high speed. The Mengzhou capsule then separated from the LAS performed a splashdown downrange.

The Mengzhou LAS powers away from the CZ-10A corse stage, carrying the Mengzhou capsule with it, as would be required should a critical malfunction occur with the Long March 10 rocket. Credit: CCTV
The Long March 10 core stage then continued a powered ascent profile, performing engine shutdown at 105 km before simulating an upper stage separation followed by a post-separation manoeuvre. This saw the stage enter “glide” phase, using its aerodynamic fins to maintain its orientation.

During this “glide” phase (actually a controlled descent, the stage orienting itself to fall engines-first), the booster carried out an automated pre-cooling of its engines in readiness for re-use and raise the pressure within the propellant tanks to settle their contents in readiness for engine re-use.

Cameras on the booster capture the deployment of the SpaceX-like grid fins on the upper end of the stage, which help it to maintain the correct orientation during its descent back to Earth. Credit: CCTV

Roughly one minute before splashdown, several of the engines successfully re-lit in a braking manoeuvre to bleed off much of the stage’s velocity. These were quickly reduced to just 3 motors and then a single motor as the stage came to a near-hover before that motor shutdown allowed it to settle smoothly and vertically in the water just 200 metres abeam of its recovery ship.

As an aside, it is interesting to contrast reporting on this flight with media coverage of SpaceX Starship “integrated flight tests”. In the case of the latter, almost every flight has been reported as some kind of spectacular success, despite most of the flights blowing up, barely meeting their assigned goals, or simply re-treading ground already covered. By contrast, the Mengzhou / CZ-10A core stage test flight has largely been defined as a “small step” in China’s progress, with some emphasising the flight “not reaching orbit” – which it was never intended to do.

In reality, the entire flight was a complete success. Not only did it demonstrate the Mengzhou vehicle’s LAS fully capable of lifting the command module and crew clear of an ascending CZ-10A should the latter suffer a malfunction during the most dynamically active phase of it flight, it also further demonstrated the capsule’s parachute descent system and its ability to make a recoverable splashdown (Mengzhou is capable of both water and land-based touchdowns, being able to be equipped with either a floatation device or airbags prior to launch).

Another still from the video of the test flight, showing the booster entering the see and its proximity to the recovery vessel, just visible on the right of the image. Future tests will see the recovery vessel attempt to “catch” a returning booster directly using a “tether” system. Credit: CCTV

Further, the test demonstrated the CZ-10A core stage’s ability to undertake a return to Earth and splashdown (again, the booster is designed to both land on a recovery ship a-la Falcon 9 and New Glenn, or make a splashdown close enough to the recovery ship so it can then be recovered – direct returns to the recovery vessel will be a part of future tests). Finally, such was the accuracy of the guidance systems, the rocket splashed down just 200 metres from the recovery ship, as planned.

That said, it is true that all the core components of the crewed phase of the Chang’e project still have a way to go before China can send a crew to the Moon. But like the tortoise, their one-step-at-a-time / keep-it-simple approach could yet see them become the first nation to do so since 1972.

Why SpaceX is most likely “Shifting from Mars to the Moon”

Thirteen months ago, in an attempt to bolster his failing “Mars colony plan” (a totally unrealistic fever dream of sending a “Battlestar Galactica” scale feet of 1,000 Starship vehicles carrying 1 million people to Mars to establish a colony there), the SpaceX CEO declared “the Moon is a distraction” and Mars was the focus for his company.

Well, he’s had 13 months to forget all that, as on the weekend of February 7th and  8th, 2026, the self-styled man who “knows more about manufacturing than anyone else alive on Earth” and yet cannot deliver on a single one of his manufacturing promises, declared that the Moon is now the focus of SpaceX’s endeavours, all as a part of a grand plan to “expand human consciousness and support his equally questionable idea of operating a 1-million strong constellation of Starlink satellites as a string of “data centres in space”. For good measure he mixes in terms such as “climbing the Kardashev scale” )the latter seems to be a particular reference point for so-called space entrepreneurs of late).

However, the real reason is liable to be far more mundane: the SpaceX CEO is again trying to justify the US $1.2 trillion valuation he and his fellow broad members arbitrarily awarded the company in January, and to justify such a figure in the face of an upcoming IPO whilst also possibly trying to further dazzle investors with shiny promises about orbital data centres and moon bases at a time when SpaceX has just “inherited”xAI and its cash burn-through of around US $1 billion a month.

The promise of a fully operational “Moon Base Alpha” (yes, once again we have a sci-fi trope to add gloss to an idea) in “10 years” will, undoubtedly go the same way as the more than a decade old claim that Tesla vehicles will be capable of full self driving “next year”; the statement that SpaceX would have Starship operational by 2022, and that Starship would fly around the Moon in 2023 and to Mars in 2024, err, 2026, err, 2028. That is to say, most likely never.

Martian Organics Cannot be Entirely Explained by Non-organic Processes

One of the major mysteries of Mars is the question of methane. It was first detected in more than faint trace amounts by the European Space Agency’s Mars Express mission in 2004. A decade later, NASA’s Mars Science Laboratory (MSL) rover Curiosity,  detected methane spikes and  organic molecules whilst exploring the floor of Gale Crater. Then in 2019, the rover a massive spike as it explored “Teal Ridge”, a formation of bedrock and deposits on “Mount Sharp” (Aeolis Mons).

Alongside of this is the vexing discovery of organic elements on Mars. These and the methane seem to point a finger towards the idea that the planet may have once harboured life. However, as even proponents of this idea point out, both organics and methane can result from purely inorganic interactions. The tick is – how to determine which might be the case.

In March 2025, Curiosity detected small amounts of decane, undecane, and dodecane in a rock sample, which constituted the largest organic compounds found on Mars to date. These offered the potential to determine which option might be more likely to cause their existence – organics or inorganic chemical reactions. All three are hydrocarbons could be fragments of fatty acids, also known as carboxylic acid.

On Earth, carboxylic acid (aka fatty acids) is a natural by-product of life. Such acid can be found in animal tissues, nuts and seeds. In the case of animal tissues, carboxylic acid is predominantly formed by the breakdown of carbohydrates by the liver and found within adipose tissue, and the mammary glands. however, they can also be created by inorganic reactions – such as lightning striking chemically rich soils (or regolith), hydrothermal interactions and photochemical reactions between ultraviolet radiation and hydrocarbon-rich mixtures.

In order to try to determine whether the fatty acids discovered by Curiosity preserved in ancient mudstone are the result of organic processes or inorganic. Whilst limited with working only with data from the rover’s Sample Analysis at Mars (SAM) spectrometer, the team sought to recreate the likely conditions on Mars some 80 million years ago – this being the amount of time the rock containing the acids would likely have been exposed to the surface atmosphere – and then work back from there to try to determine which would survive the longest: carboxylic acid produced by organic or inorganic means.

What they found was that organic mechanisms appear to leave far more in the way of organic remnants – such as decane, undecane, and dodecane – than the typical non-biological processes involved in forming carboxylic acid could produce. The team suggest that this might be because any organics responsible for the fatty acids might have been assisted by periodic impacts by carbonaceous meteorites, known to be sources of fatty acids formed in space.

However the team also urge caution: whilst their finding might move the needle further towards the idea that Mars once harboured life, they also clearly note that there is a need for greater study; Mars is a complex world, rich in complex interactions. As such, more and detailed study is required – preferably first-hand, through the obtaining of samples from Mars itself. Currently, and rather ironically, whilst NASA had planned to make samples from the Mars 2020 rover Perseverance available for return to Earth, these do not contain samples of a similar nature to those found by Curiosity.

More particularly, at the time Perseverance had launched to Mars with sample retrieval in mind, no-one had actually sorted out how such a retrieval might be achieved. As such, a series of highly complicated, overly expensive proposals were put forward, involving both US and European co-operation. Each of these were knocked down on the basis of complexity and escalating price – up to US $11 billion – or close to half of NASA’s overall budget – for such a mission was just too big an ask. Thus, despite more cost-effective proposals such has Rocket Lab’s (still complex) three-launch mission slated to cost a “mere” US $4 billion, the entire idea of a sample return mission has been cancelled as a result of NASA’s budget being tightened.

Upcoming Viewers

Viewer 2026.01

  • Remains the current viewer development focus with the release of the beta (RC) version, although this will be shifting more to 2026.02.
  • The velopack one click installer / updater is not in the initial beta, but is “off to one side” whilst being allowed to “cook” for longer. This may get folded back into 2026.01, but the Lab is not “super married” to this being the case.
  • 2026.01 includes a high priority fix for specific Bluetooth headset configurations which will benefit WebRTC.
  • Now available as an alpha viewer (above).
  • As the name suggests, triggers a one-click install / viewer update process.
  • Also includes improved monitoring / logging of viewer freezes and crashes, etc.

Viewer 2026.02

  • 2026.02 remains on track for the “Flat” UI and font updates.
  • It now also includes the WebRTC voice moderation capabilities (as seen in the project viewer) to help align viewer-side WebRTC updates more with the hoped-for server-side deployment currently targeting March 2026.
  • No Alpha / Beta viewer is available as yet for this release..

Viewer 2026.03

  • 2026.03 is described as a “visual polish” for the viewer. This viewer is likely to include:
    • The “long baking” SSR improvements that were started last year. This version of the viewer will likely have a long beta soak time to allow feedback on these changes to be gathered.
    • PBR specular for residents who are more familiar with the old Blinn-Phong work flow. This will:
      • Include another texture slot (tint of the specular reflection).
      • Work with metallics.
      • Follow the glTF specification, but will likely initially be without glTF overrides, as this requires server-side work.
    • HDR controls in EEP so residents can decide how bright or dark things should be. This work does require simulator-side updates. This will likely initially have server-side support on Aditi (the Beta grid).
  • The Pull Request  for this work can be found here – #5385.
  • 2026.03 is looking towards an April release.

General Viewer Notes

  • Viewer-side Blinn-Phong alpha-gamma improvements were raised as possible inclusion for 2026.03. The Lab’s viewer is that while these will be coming, it will not be until after supporting server-side updates have been made in order to avoid what the Lab sees as potential content breakage. This matter was viewed as “not up for debate”.
    • There is a chance that the server-side work might be undertaken and completed in time for the viewer-side fixes to be included in 2026.03, but currently, Geenz isn’t willing to commit to this due to other on-going work.
  • User Animats is developing the Sharpview viewer. This includes an “infinite draw distance” – see this video as an example.
    • The Lab has been looking over this work internally, and there has been some discussion on supporting the work and giving it more of an official path.
    • Geenz noted having the map system provide terrain heightmaps could be a start.
    • Geenz also suggested having prim stand-ins for distant objects, but noted that this is a “down the road thing”.
  • Geenz Linden has requested developers put their eyes on PR #5429.
    • The release ordering for this would b after the SLua works reaches release status, due to both that viewer and this work having ties to the the official Linux viewer build.
    • It is unlikely the SLua work will be merged into a main viewer code until around the 2026.04 viewer, which means the work in PR#5429 is unlikely to reach a viewer release until summer.
    • Given the changes it may bring to some TPVs, this is seen as no bad thing, as it gives the opportunity for feedback and planning, etc.
  • A general discussion on re-enabling water reflections as a part of the upcoming SSR / HDR improvements. Options were mentioned, and Geenz seemed to lean towards “a slight optimization to mirrors on thin probes is not out of the question to help ‘backfill’ probe data”, before noting this would have to be very narrowly scoped for inclusion in the 2026.03 viewer.
  • The transmission index of refraction (IoR – good for water reflections) project is seen as requiring more time and input than the PBR specular work, despite a good amount of work being done on the transmission / IoR work. As such, it is awaiting a re-prioritisation to continue – and this might be a while before it is forthcoming, because there is still a fair amount of complexity involved in any implementation.
  • A general discussion towards the end of the OSG meeting on HDR, HDR skies, improving the brightness of the SL Sun, etc.

Grid-Wide WebRTC Deployment

  • The Lab is currently looking at a March deployment of WebRTC voice across the grid, but this is subject to possible change.
  • The viewer server is currently in a beta soak test (see: WebRTC Voice Open Beta is Expanding).
  • Deployment will follow the usual simulator update route:
    • First week: limited deployment to selected RC channels (e.g. Bluesteel / Preflight).
    • Second week (providing no significant issues occurring): wider deployment to all RC channels.
    • Third week: deployment to the Main SLS channel, marking WebRTC as grid-wide.
  • As noted in the viewer notes above, there are fixes going into the upcoming 2026.01 viewer related to WebRTC:
    • These are each described as affecting a “small number” of users.
    • The first fixes an issue where some people may lose voice without reconnecting once in a while.
    • The second relates to problems with certain Bluetooth headsets losing audio after toggling PTT.
    • LL would ideally link to see TPVs cheery-pick these fixes for inclusion in their viewers so as to be available to users as WebRTC commences deployment.
  • A server-side  fix to address a spatialization bug was released on Monday February 9th, and appears to have dealt with the last known significant server bug.

CCUG Meeting General Discussions

  • A request was made for a check box to be added to the PDR editing tools to ignore the alpha channel in order to allow Blinn-Phong specular textures could be re-used.
    • This was seen as a “little tricky” given the way BP specular has been implemented in SL, which have resulted in some compatibility between BP and PBR (e.g. the colour RGB parts), whilst others are not.
    • Whilst some comprises could potentially be mead, they would deviate away from the glTF specification, which is not what LL wants to do.
  •  Geenz indicated he is mulling the idea of possible adjustments to texture streaming to help improve it – such as streaming specular, metallic and even base colour at lower resolutions, whist keeping the normal map at the required resolution. This, he feels would compensate for any loss of detail on specular, metallic or base colour, whilst decreasing the overall streaming load.
  • Scriptable IK was raised as an idea. This was something the currently suspended Puppetry Project was looking at, as well as things like use of webcams for animations, etc. It is not clear if / when this work might be re-animated (no pun intended).
  • Blend shapes / custom rigs were again raised for discussion, with Geenz again noting that the issue is in part a problem with the internal SLMesh format used by SL not being particularly flexible.
    • Before anything could be done to support things like custom rigs and similar, there would need to be a new implementation of the SLMesh pipeline.
    • This would allow LL to develop a new, more flexible SLMesh format, which is more resilient to things like unexpected data and would also allow support for new fields (e.g. bland shapes – which could even be hooked up to the current slider system and / or be scriptable, etc).
    • However, such a project would be relatively long-term and require consideration of other issues (e.g. support for over 20 years of animations which will continue to require support and thus would need things like retargeting).
    • Therefore how to fit it into the roadmap and ensure the required resources are available is not currently clear given the number of other priorities already in play / awaiting attention.
  • The above encompassed a discussion on external tools which might help in look creation, clothes fitting, etc., such as Character Creator and Marvelous Designer, which can be used with SL as an external tool, whilst having a good level of integration into Sansar .
