Frank’s Echoes of Illusion at Nitroglobus, Second Life

The Annex, Nitroglobus, Sept / Oct 2024: Frank Atisso – Echoes of Illusion

Frank Atisso makes a return to The Annex at Dido Haas’ Nitroglobus Roof Gallery for September  / October with Echoes of Illusion, a selection of bold – in a literal sense – images that offer a series of challenges to be considered; some of which are intentional on the part of the the artist – as he states as much in his own introduction to the exhibition – others of which, given the nature of the world in which we currently live might well not be entirely the artist’s intent, but which may nevertheless resonate with those viewing the pieces.

Frank explains Echoes of Illusion thus:

The images I created … reflect and amplify the deceptive nature of concepts like peace and freedom.
I chose the combination of black, white, and red as it best represents the stark contrasts and underlying truths of these dark themes, highlighting how illusions and false promises resonate and reverberate through society.

– Frank Atisso, introducing Echoes of Illusion

The Annex, Nitroglobus, Sept / Oct 2024: Frank Atisso – Echoes of Illusion

Thus on offer are nine very large images presented purely in red and/or black and/or white. Each one can be interpreted both directly and indirectly, and many carry the idea that contrary to the general (and mistaken) perception that white is akin to purity and goodness and black and red are so often associated more with anger, violence, darkness and death, as with many things in life, things are not so clear cut, and the purity of white can veil much that is itself harmful or hold harmful intent. Within them is also that broader commentary on the current state of society to which Frank alludes, and the increasingly pervasive dangers of false promises and the use of disinformation to blind people to realities that could so easily entrap them.

The best way to appreciate each image is to right-click it and view the title, and then allow it and the title to permeate your thoughts. In this way the core meaning of an image is readily identified, whilst the mind is free to consider it in light of the aforementioned boarder state of increasingly polarised (particularly western) societies: the echo chambers of social media; the aggravation of ill-conceived “injustices” as a means to foment anger and resentment under the guise of bringing hope, strength and security; the false realities of so-called wealthy “thought leaders” and their thirst for authoritarian control of those they seek to persuade and the reality that they care little for the welfare of those same followers, other than then heed the call and be ready to spread divisiveness and inflict chaos, no matter what the cost to themselves or their own rights.

The Annex, Nitroglobus, Sept / Oct 2024: Frank Atisso – Echoes of Illusion

It is because there is so much potential here, coupled with the fact that outside of Second Life I hold very particular views concerning those leading the extreme right and the realities of their words and deeds which has already potentially biased my commentary, that I do not want to inflict my own views further on this exhibition. Instead I urge you to go along and spend time within it and allow it to speak to you.

Grauland’s primary colours in Second Life

Grauland / Primary Colors, September 2024 – click any image for full size

Cube Republic gave me a poke in the ribs recently to suggest I hop back over to Jim Garand’s Grauland to see what Jim has done since my last visit. As I’ve frequently noted, I enjoy visiting Jim’s work and writing about it, but the first time I popped over to visit this iteration, I was interrupted by a bout of “real life” and didn’t have time to see much. Fortunately, the past few days have enabled me to hop back, so here we are.

With Grauland / Primary Colors, Jim takes us into the American heartlands (at least going by one of the billboards) and an industrial setting of a chemical plant of some description. It appears to be producing vivid primary colours for who-know-what purpose (perhaps they are for painting prims shipped from the Prim Rig in the ANWR Channel 😀 ).

Grauland / Primary Colors, September 2024

Sitting alongside a busy road, the complex is impressive and speaks to a slick operation.  The bulk raw materials arrive by rail to be dropped from their hopper cars as they sit on elevated track. From here, they’re bulldozed into piles so that articulated yellow loaders can scoop them up for transfer into more hoppers where they can be conveyed to huge tanks. Once in these, they appear to be dissolved into a a liquid mix, and so pass onwards through associated processing (including the burning-off of waste product) to eventually end up in tanker wagons as finished goods, ready to be hauled of along the very same rails they arrived on.

Part of the processing also seems to involve deliveries by road through the plant’s main gates, the materials stored in a small warehouse on that side of the grounds. Everything appears to be watched over from the vantage point of a control room sitting to one side of the main plant on four stout concrete legs. Although, looking at the screen savers on a couple of the PCs in the room, staff there would appear to at times have their minds on things other than monitoring systems!

Grauland / Primary Colors, September 2024

Throughout the tanks, risers, piping, silos and whatnot are ground-level and elevated walkways and catwalks offering visitors the opportunity to explore the complex in detail, whilst the surrounding hills make it clear the place is well inland and away from the sea. Exactly where it might be is left to the imagination; one of the billboards hints it might be along Route 66 and maybe in Missouri – why else the advert on the board? – But this is pure supposition on my part, although said ad did allow me to learn that “The Best Fudge Comes from Uranus” really is an advertising slogan for a tourist attraction on US Route 66 in Missouri.

This is a setting with a lot of subtle detail built-in; the screen savers on the computers suggests the desire to break with the cycle of  mundane duty when at work; the condition of some of the towers and storage tanks give the impression of age while the colour-coding on some of the pipes gives a further sense of authenticity, as do thinks like the first aid equipment at the gate house. Some of the controls in the main building have some curious labelling – but such is the way of things when building a scene in Second Life, and certainly nothing to complain about.

Grauland / Primary Colors, September 2024

With the landing point (which includes the teleport up to Jim’s M1 Poses store) located in the north-west corner of the region, this is a setting that spreads itself out before you to the east and south as you arrive, begging to be explored (and I liked the way the north edge of the region has been raised to suggest spoil tips from the plant that have been in place so long, the local grass has claimed them even as they denote the edge of the walkable region and the start or the encompassing region surround).

Opportunities for photography abound through the setting, particularly for those who appreciate a more industrial background to their avatar studies. So with that said, I’ll leave you to hop along and see for yourselves.

A Spoonful of Sugar 2024 in Second Life

via Spoonful of Sugar 2024

Now open through until Sunday, September 22nd, 2024 (inclusive) in Second Life is the 2024 edition of the Spoonful of Sugar festival in support of Médecins Sans Frontières (MSF), the globe-spanning non-profit organisation delivering emergency and humanitarian aid to people affected by armed conflict, epidemics, natural disasters and similar.

Also known as Doctors Without Borders, MSF was originally founded in Paris, France in 1971 and is entirely self-governing; the support and treatment it provides is given on the basis of need, irrespective of race, religion, gender or political affiliation. It is often one of the first organisations to have feet on the ground wherever and whenever humanitarian aid and medical support is desperately needed, and since its founding, MSF has grown to a movement of 24 associations, bound together as MSF International, now based in Switzerland. Thousands of health professionals, logistical and administrative staff – most of whom are hired locally in respect of the care they give around the world – work on programmes in some 70 countries worldwide to provide medical and social care & support for a staggering 10+ million people annually.

Since its own establishment, the SOS event has raised more than US $100,000 for MSF’s global work, in keeping with its mission statement.

We believe the simplest form of compassion is to simply care for the life of another. And we believe medical care to be the most fundamentally basic means by which to do that.

– The Spoonful Of Sugar Festival Mission Statement

Spoonful of Sugar 2024 (September 7th-22nd)

This year, SOS is taking place across a total of six regions with the theme of En France!, with five of the six regions very much focused on MSF’s founding city of Paris. Four of these regions present the core shopping elements to the event, each one presented as scene featuring the kind of French townhouses and business façades found along places like the Champs-Élysées, surrounding a central area representative of I. M. Pei’s glass-and-metal Louvre Pyramid, located in the Palace’s Cour Napoléon.

With pairs of these regions sitting to either side, the two central regions are more open in their design. The first forms the main landing point and activities venue for SOS, and is dominated by the Eiffel Tower and the park below it, into which has also been placed a giant Ferris wheel, which I take as representing the 60-metre wheel at the Tuileries Gardens. This region – SOS Uber Global – is connected to two of the shopping regions by bridges, with a further bridge connecting it to the other central region in the group.

The latter is mindful of rural France, and is home to various spaces given over to breedables, landscaping and gardening – and most notably, a special 10th anniversary art display presented by Harmonic Sanctuary, founded and operated by Harlow Jones Blues (harlowjones) and Jess Blues (JessBlues).

Une Célébration Du Pays Basque, spoonful of Sugar 2024 (September 7th-22nd)

Une Célébration Du Pays Basque “takes you on a journey through the stunning landscapes and rich culture of the Basque region of France”. Centred on a watermill similar to those which might found in the region, and here offered and in homage to Jess’ father, who was born in such a building. The exhibition offers a rich and engaging collection of images in celebration of the French Basque region – the landscape, the people and the lifestyle, with an additional display of art located in the cave to one side of the gallery building.

Beyond this, the setting continues as a place to explore and spend time within, and I recommended taking time to pick up a note card from the information board at the gallery’s landing point. It contains a wealth of information that’s worth the time taken to read it – and remember that much of the art (produced by Jess and Harlow) is offered for sale exclusively at SOS, with a goodly portion of the cost going directly to the event.

Spoonful of Sugar 2024 (September 7th-22nd)

The best way to find out about all that’s going on at SOS 2024 and which stores are where within the region is via the official website, where you can find the schedule of entertainment, and the region list page with SLurls directly to all stores and points of interest. The base of the Eiffel Tower is the location for the event’s raffle, and also a place where Animesh mime artists can be found performing (this is Paris, after all!), with a select of low-cost items with 100% of all proceeds going to the event right next to them. I didn’t notice any hunt this year – but might have missed it in my travels.

As always, Spoonful of Sugar is an event well worth visiting. Even if you don’t find anything to buy in the shopping regions, the donation kiosks will welcome your Linden dollars, and you can be absolutely sure that your money is going to a very worthy cause.

The misty beauty of Jade’s Derryclare Loughin Second Life

Loch Dhoire an Chláir, September 2024 – click any image for full size

Ireland (or Éire if you prefer) covers an area of just under 70,300 square kilometres; but while small (ranking 118th on the list of countries by total area), it is one of the most stunningly (and romantically) beautiful to visit, its comparatively small size allowing so much of it to be easily appreciated in a single visit.

One of the most beautiful parts of Ireland – for me, anyway – is Connemara, County Galway. Located on the west of Ireland and facing off against the Atlantic, Connemara has a magnificent coastline with multiple peninsulas, whilst just s short distance inland lay mountains such as the Twelve Bens / Pins (Na Beanna Beola) and the Maumturks / Maamturks (Sléibhte Mhám Toirc) together with the Pantry and Sheffrey ranges, all of which border the magnificent Connemara National Park, numerous rivers and lakes and lochs.

Loch Dhoire an Chláir, September 2024

Connemara is also famous for its strong roots in traditional Irish culture, the fascinating history of mining within its borders (tours of some of the mines are available) and which sought Connemara Green Marble, copper pyrite, and minerals and gemstones in general. It’s also the point of arrival for Alcock and Brown and the end of their 1919 historic non-stop trans-Atlantic flight – and a lot more besides.

However, it the the region’s lochs that were the focus of my most recent excursion within Second Life. This is because Jade Koltai recently overhauled her Homestead region of Overland Hills to present another setting inspired by a physical world location: Derryclare Lough, a freshwater lake within Connemara located near the southern end of the Twelve Bens, and from which she has borrowed its Irish name, Loch Dhoire an Chláir.

Loch Dhoire an Chláir, September 2024

Sitting at the mouth of the Inagh Valley and fed by water flowing to of the nearby Lough Inagh further up the valley, Derryclare Lough is so-named as it is close to the Derryclare mountain as it sits at the southern end of the Twelve Bens range. It is a lake perhaps most famous for its fishing, its conifer woods, its distinctive island reached via a stone causeway cutting through its shallows, and for being a favourite spot for photographers who have visited it from across the world.

The latter have, over the years, produced an plethora of beautiful images of the lake and its dramatic surroundings. Most of these feature the lake and its island under balmy summer skies, often at sunset. They are images that soften the area’s ruggedness into a more romantic idyl-like beauty. However, Jade eschews such a look for her design; offering something more in keeping with the weather that can sweep into Connemara from the nearby Atlantic, presenting a setting that is heavily overcast, the clouds lowering and spitting forth rain; the mountains and hills cast into the role of brooding hulks as they rise from the more distant landscape, their peaks silhouetted against the clouds and their shoulders wrapped in misty haze and their feet lost in shadow.

Loch Dhoire an Chláir, September 2024

It’s an excellent choice, giving the entire setting an air of mystery and intrigue which helps set it as a place very much inspired by rather than modelled on the actual loch. This allows Jade to present a setting that carries the essentials of Derryclare Lough – the waters of the lake, the island within it, the peaks of the Twelve Bens – whilst also potentially casting her net wider to capture more of the essence of Connemara as whole.

Thus, within the setting come much of the rugged beauty of the peat bogs and moors of the region, a hint of the loneliness of crofting – even something of Connemara’s Medieval history. This takes the form of ruins of a castle / fortified house (courtesy of Marcthur Goosson, whose work forms the backbone of my own island home in Second Norway), which perhaps offers a hint of Clifden Castle with it arched entrance and single tower.

Loch Dhoire an Chláir, September 2024

Jade’s use of region surrounds to create a sense of the mountains bordering the lough and to give added depth and life to the setting is simply superb; it’s easy to imagine you could just step off the region itself and strike out towards the rising peaks and perhaps find yourself on the Glencoaghan Horseshoe. Closer to home, the little crofter’s cottage located to one side of the setting perhaps also stands in place of the numerous small cottages that can be found along the shores of the lake and which can be used (with a suitable licence) as a base to go fishing on the waters of the lake and the rivers flowing into and from it.

Fishing on the lake is most often carried out from the “butts”  – piers extending out from the shore -, and these are also represented within Jade’s build, as is the distinctive wooded island and the long stone causeway reaching out to it. The latter allows visitors walk out to the island and, should the need to escape the rain  be felt, the tents set out on the island might provide it. Forming a little camp site, they are one of several places visitors can sit and pass the time to be found throughout the setting. Another such place sits to the south of the land, not too far from the ruins. A single wooden chair sits looking out over the the more distant land, a blanket draped over it and a lantern illuminating the ground in which it stands. To one side of the chair is a flat-topped boulder suggestive of a flat cairn topped by a cross and a vase of red roses. It’s a poignant little vignette, one suggestive of a place of memory and solace; one that adds yet more depth to the setting.

Loch Dhoire an Chláir, September 2024

However, the best way to appreciate the setting is obviously to visit it. When you do so, make sure you have local sounds enabled to capture more of the region’s ambience. I’d also advise sticking with the local environment to fully appreciate Loch Dhoire an Chláir as intended by Jade. All told, another beautiful and atmospheric setting – and one not to be missed.

2024 week #36: SL CCUG summary: viewer performance and aesthetics

Goblins Knob, August 2024 – blog post
The following notes were taken from my audio recording and chat log transcript of the Content Creation User Group (CCUG) meeting held on Thursday,  September 5th, 2024.

The meeting was also livesteamed on You Tube by the Lab. The video is embedded at the end of this summary, my thanks to the Lab for providing it.

Table of Contents

Meeting Purpose

  • The CCUG meeting is for discussion of work related to content creation in Second Life, including current and upcoming LL projects, and encompasses requests or comments from the community, together with related viewer development work. This meeting is held on alternate Thursdays at Hippotropolis.
  • Meeting dates and times are recorded in the SL Public Calendar, and they re conducted in a mix of Voice and text chat.
  • The notes herein are a summary of topics discussed and are not intended to be a full transcript of the meeting.

Official Viewers Status

  • Release viewer: version 7.1.9.10515727195, formerly the Atlasaurus RC (object take options; improved MOAP URL handling) promoted August 26.
  • Release channel cohorts:
    • DeltaFPS RC, version 7.1.10.10708851543, updated September 5.
      • Performance boosts. Memory management has been optimized and users will experience a higher FPS across various systems. A comprehensive range of bug fixes are also provided. This includes better PBR material handling and resolving frequent crashes. See the release notes for more.
      • UI for scheduling region restarts now available via a new button located in the Region/Estate floater. (Note: there is currently an issue with scheduled region restarts working correctly and a fix is due to come in the next server release).

Viewer Performance – Priorities

[Video 1:15-3:03]

  • The performance setbacks between the original PBR viewer release (7.1.6) and the Graphics Featurettes viewer (7.1.8), and which particularly negatively hit the Firestorm PBR release were again covered (for additional content, see my August 30th TPVD meeting summary).
  • This has resulted in a “significant portion” of the viewer development work being focused on recovering performance and rectifying the underpinning bugs and issues – some of which are not specific to the PBR implementation itself. Some of this work has been surfaced in the DeltaFPS viewer, but more is to come.
  • The above work also folds into it various fixes for crashes and bugs and a number of Visual Aesthetics (as in how SL looks – see below).
  • This work will impact other areas of viewer work, so glTF projects like the PBR Terrain Painting and Transmission / IOR work are going to be pushed back somewhat, as is work on the viewer-side implementation of Laua scripting support. However, all of these work is still on the roadmap, just delayed.
  • [Video: 8:24-8:56] Cosmic Linden has been working on an improvement to avatar loading to assist with performance improvements, and this has been pushed to the DeltaFPS RC viewer, together with working on bug fixes.
  • [Video: 9:00-9:54] Runitai re-iterated that the Graphics Featurette viewer introduced the major performance hits (some of which are related to bounding box management and memory management, the the TPVD notes linked-to above), and DeltaFPS sees a good improvement in performance over Graphics Featurettes, and the viewer in development (“ExtraFPS) that will follow DeltaFPS should see performance return to levels seen with the initial PBR release.
  • [Video: 45:46-46:36] Which is not to say there are not additional PBR-related performance problems – such as those tied to specific GPU such as the Nividia GT1030 2Gb. These are also the subject of fixes being implemented in either the DeltaFPS viewer or the upcoming ExtraFPS viewer that will follow it.

Viewer Aesthetic Updates

[Video: 4:54-8:10]

  • Linear alpha blending: in order for PBR lighting to render anywhere close to correctly, alpha blending has to be switched from SRGB to linear colour space. This can cause some older content using Blinn-Phong to look either more opaque or more transparent than in did pre-PBR.
    • The fix for this will likely be to add the ability for people to set and alpha/gamma ramp on an item, which can be modified per texture entry, adjusting how transparent the item is on a curve.
      • This should help with a range of issues – particularly those associated with pre-PBR hair, as has been noted by an number of users.
      • To help with this, the new alpha/gamma ramp value will still be adjustable even if the content is No Mod, so as to allow users to adjust legacy content affected by the issue, rather than having to wait for  fixes from content creators.
    • This fix will hopefully follow in the ExtraFPS viewer after DeltaFPS, but in the meantime will be made available in a viewer build available through the Content Creation Discord group‡ for those wishing to test it once the initial work has been completed.
    • Runitai Linden also indicated that as an extension to this work, LL might be able to find a way to apply the adjustment automatically, rather than people having to manually set it, but also noted any automatic solution would be “hard”.
  • Auto-exposure: LL is looking to add controls for dynamic exposure (speed of transition, range, ability to turn off / on). These options will be made available via the Advanced Graphics floater, and maybe / someday via the the sky settings floaters.
  • [Video: 10:03 -10:50] Anti-aliasing: there has been negative feedback from those who used to run the viewer with Advanced Graphics Model (ALM) disabled and who are forced to have it enabled all the time as a part of the PBR rendering, don’t like the look of Fast Approximate Anti-Aliasing (FXAA) as used in the viewer, so LL are adding support for Subpixel Morphological Anti-Aliasing (SMAA).
    • In addition, Rye Cogtail from the Alchemy team did a pass on the FXAA code and found it was not working as well as it should be.
    • Updates to FXAA and the addition to SMAA will be appearing in the viewer to follow DeltaFPS.
    • Those requiring more insight into anti-aliasing and the various types of AA, including FXAA and SMAA, can find out more in What Is Anti-Aliasing? TAA, FXAA, DLAA And More Explained, via Digitaltrends.
  • Work is also being put into smoothing the problems created by switching from 8-bit colour precision to 16-bit float colour precision (which can be the cause of bugs wherein you go somewhere in SL and everything glitches to black or solid white). This work should surface through DeltaFPS.
  • [Video: 11:05-11:45] The Sun is unrealistically dim. LL are considering adding a specific Sun intensity multiplier to Sky settings.
    • As a temporary fix, and whilst not specifically addressing the sun issue, the overall brightness in a scene can be adjusted via very small tweaks to the HDR slider in the Personal Lighting floater.
  • [Video: 49:16-56:05] Tone mapping: Rye Cogtail from the Alchemy team has contributed the Khronos Neutral tone mapper for inclusion into the viewer.
    • This is not as dark as the current default in the viewer, and initially will use debugs to select which tone mapper is used (as the existing mapper will remain).
    • LL are looking to make this the default for tone mapping (subject to the outcome of testing), and the mapper is currently in the viewer Develop branch for TPV / viewer builders to take a look at.
    • When implemented the controls will likely be in the Advanced Graphics settings as a combo box and a slider. The control may also in the future be added to the sky settings.
    • In addition, there will be a new control – Tone Mapping Strength – to alter the linear alpha colour.
    • A key point to content creators on this is: you should not put the tone mapper in your textures (e.g. via the options available in PhotoShop when exporting textures) by bumping saturation, etc., and baking the tone mapper into the texture (as well and not baking things like reflections into textures).
    • WYSIWYG will still be possible providing creators select a tone mapper in SL that matches the mapper in their tool of choice or by using no post and working in linear + using the HDRI Preview option (Develop(er) > Render Tests) and use the same HDRI in SL as your content creation tool.

WebRTC

[Video 3:05-4:26]

Summary

  • A new project intended to move Second Life away from reliance on the Vivox voice service and plug-in, and to using the WebRTC communications protocol (RTC=”real-time communication”). Roxie Linden is leading this work.
  • Key benefits:
    • WebRTC supports a wide range of real-time communications tools in common use (e.g. Google Meet), supporting audio, video and data communications, and is thus something of a “standard” approach.
    • Offers a good range of features: automatic echo cancellation, better noise cancellation and automatic gain control, much improved audio sampling rates for improved audio quality.
    • Opens the door to features and capabilities to voice services which could not be implemented whilst using Vivox.

Status

  • WebRTC is now fully supported in the official viewer.
  • The back-end deployment on the simulator servers is progressing (2 release candidate channels for simulator servers – BlueSteel and Ferrari – should now have WebRTC support), but this is not yet universal across the entire grid, and will take at least another 2 weeks to be grid-wide.
  • Throwing the switch from running Vivox on the back-end to running WebRTC only will be dependent upon third-party viewers implementing and releasing the viewer-side WebRTC library.
  • In the meantime, peer-to-peer and ad-hoc WebRTC can be tested on the WebRTC regions of WebRTC Voice 1, WebRTC Voice 2, WebRTC Voice 3 and WebRTC Voice 4. However, there is no bridging between WebRTC peer-to-peer  / ad-hoc and Vivox.

In Brief

  • [Video 17:06-25:06] A discussion on Marvelous Designer (MD) cloth simulation within Second Life. This was done with Sansar, allowing clothing to be properly draped over an avatar body, and allowed for adjustments to be made prior to the finished results being baked-out (with automatic hidden surface removal).
    • Second Life utilises a different data modern to Sansar which introduces a range of complexities that would require significant re-working of how clothing  / mesh data is management, a potential re-writing of the entire Bake Service and other factors, all of which make MD integration a challenge.
    • Further complexities are added by the fact that unlike Sansar, which utilised a single avatar body type, SL has a plethora of bodies, and so using the cloth simulation against different body types (whether by creators or users) gets considerably more complicated, as do the requirements for data handling / storage and the costs involved.
    • As such, whilst these issues are not necessarily complete barriers to integration, they do mean that there are significant considerations involved, as well as significant changes to SL that would have to be made. Thus, it is not currently on the roadmap or under current consideration.
    • Please refer to the video for further details.
  • [Video: 25:16-26:12] 2K texture support for Bakes on Mesh – while there was no precisely update available:
    •  It is believed the majority of the work in enabling 2K Bakes on Mesh is now done in terms of getting an early prototype put together on one of the Lab’s own development grids.
    • However, there is currently no public availability for the capability, not is there any release schedule. The work remaining “on-going”.
  • [Video: 26:31-28:50] A brief discussion on creating content with both Blinn-Phong and PBR materials and some of the issues that can occur + some of the slight eccentricities (e.g. objects with both appearing to turn metallic when edited).
    • It was noted that as Blinn-Phong is still supported, creators can continue to use that in preference to PBR materials, although as time goes on the underpinning tools (like Blender) might move more and more into the glTF support arena and make it easier to produce glTF compliant content which can be used in SL.
  • [Video: 29:14-30:57] Transmission and IoR: these are being implemented against the glTF extensions approved by Khronos. This work is focused on implementing them against the prototype glTF implementation, then it they pass that, the focus will move to integration with SL and how they work with glTF materials assets and how to apply them to mesh and prim faces.
    • However, as noted above, this work is currently paused pending completion of the performance improvements work, and is unlikely to resume until after the viewer following Delta FPS has surfaced.
    • It was also noted that it will still be a while before LL are confident enough with both Transmission and IoR to allow either to be added to content be users, even on a test basis.
  • [Video: 40:22-41:48] The question was asked that, when SL gets glTF morph targets, if it would be possible to swap out vertex maps as well to change vertex weights so that it might be possible to deform clothing using the morph targets via script, then change the rigging, so an to allow one-size-fits-all clothing.
    • Runitai Linden noted that LL are aiming to hit all of the “musts” and “shoulds” in the glTF  specification. For morph targets, this means effectively having three channels per mesh that can be modified with the morph slider, thus limiting what could be done.
  • [Video: 42:10-44:55] llSetAlpha / llSetColor, etc: LL is planning on making these functions implicitly access the PBR equivalents when a PBR material is present. However, this is hampered by the fact a good proportion of users are still on non-PBR viewers, so “there’s not good answer to which channel it should modify.” This means that currently, the easiest thing it to leave the functions “as is” until sufficient enough users are on viewer with PBR support.
    • This does not mean non-PBR content will no longer be a thing; just that creators should not have to make a non-PBR version of their content because there are people still using a non-PBR capable viewer.
  • The last few minutes of the meeting are spent discussing what additional elements of the glTF specification have yet to be worked on.
