SL project updates 2017 10/2: Content Creation User Group w/audio

The gathering: people gather for the CCUG, including a ridable dragon, a work-in-progress by Teager (l) and a wearable dragon, also a WIP by Thornleaf (r)
The Content Creation User Group meeting, Thursdays, 13:00 SLT

The following notes are taken from the Content Creation User Group meeting, held on  Thursday March 9th, 2017 at 1:00pm SLT at the the Hippotropolis Campfire Circle. The meeting is chaired by Vir Linden, and agenda notes, etc, are available on the Content Creation User Group wiki page.

HTTP Fetching

As I’ve noted in several recent SL project updates, the Lab is shifting the fetching landmarks, gestures, animations, shapes, sounds and wearables (system layer clothing) away from UDP through the simulators and to HTTP via the CDN(s).

The simulator side of the code is already in place on Aditi and awaiting further testing (see here for more). Vir is heading-up the viewer side changes required to support this work, which is now getting “petty close” to being available in a public viewer (most likely a project viewer). I’ll continue to update on this work through my various SL project update reports.

Rendering Costs

Vir has also been looking at the viewer-side rendering costs of various avatar models to improve the overall rendering cost calculations. This is more a data gathering exercise at the moment, but it is hoped it will lead to improved calculations when determining the overall rendering complexity of models, and will likely mean that, for example, the cost of rendering rigged meshes will at some point be updated.

This isn’t directly related to the potential of animating objects (e.g. for non-player characters). While the Lab is apparently still pondering on this as a possible project, it would mean back-end changes to calculate the land impact of avatar models used as NPCs, rather than alterations to the viewer-side rendering cost.

Animation Transitions

There have been, and continue to be, a number of issues with animation playback, some of which appear to be related to llSetAnimationOverride, one of the server-side functions for controlling your animation state. Some of these were reported early on in Bento, which exacerbated some of them (e.g. quadrupeds crossing their forepaws).

Issues can also occur with jump animation states (pre-jump, jump and landing), as has been reported in BUG-7488. For example, During the meeting, Troy Linden and Medhue Simoni pointed to problems: for Troy, it was with respect of an avatar “sticking” in the landing animation, rather than returning to the expected standing animation; Medhue reports issues in general playback, and whether the transitions will actually play correctly.

It not clear if these issues are all a part of the same problem, but feedback from the meeting is being relayed back to those at the Lab poking at things.

Information and Tools

People are still having problems finding Bento information on the SL wiki – such as the skeleton files. This is partially due to the files being on the Bento Testing page.  It’s also not easy for new creators to find information on suitable tools (e.g. Avastar. MayaStar, etc.).

One suggested solution (allowing for the wiki currently being locked from general edits) is to have a general SL tools page where the various tools, etc. can be listed with links to their respective websites. This could include free tools: GIMP, Blender, Wingz 3D, etc.), plus tools which are not specific to SL can be used within (e.g. Maya, Zbrush, etc), and then add-ons like Avastar and Mayastar.

Such an approach, coupled with a clean-up of the Bento information, might be suited to being included in an overhaul of the wiki Good Building Practices pages the Lab is working on as and when resources are available. Troy has made a note to take these ideas back to the Lab.

Other Items

Transparency Rendering Cost

There was some discussion on whether the rendering cost of a rigged mesh should remain high if it is set to transparent. Some felt the cost should be lower, and Vir noted that the system avatar has a special UUID for an invisible texture when can reduce the rendering cost of the system avatar. However, rigged meshes may not be subject to this check, which may also depend on how the mesh is made transparent (i.e. via a texture or via the transparency setting). He also noted that rendering as transparent could add cost over rendering a rigged mesh as opaque.

There was some discussion on whether simply having the mesh in memory, whether or not it is rendered, could add to its complexity. Vir indicated that as he’s not precisely sure how things are handled, he’d have a look at the code.

Calling Animation UUIDs via Script without the Animation Residing in Inventory

A question was asked whether it would be possible to have a script call an animation via the animation’s UUID without the animation being physically in the parent object’s inventory. The short answer to this is “no”.

While animations can be pulled from objects with modify permissions and used elsewhere, many items with animations (chairs, beds, etc.), tend to have animations in them set to No Copy, limiting the ability to freely re-use them. If animations could be freely called via script using their UUID, this protection would be eliminated, as anyone with the UUID could use the animation as often as they wished, regardless of whether or not a version of the animation resides in their inventory.

This conversation edged into the issue of people being able to pull Copy permissioned inventory from a No Modify object by opening it; however, that is something of a separate situation, which was not discussed further.

Avastar Status

AvaStar is now at release candidate 4, with RC 5 on its way, which may be the final RC before a release.

.ANIM Exporter for Maya

Aura Linden is re-working the code on her open-source Maya .ANIM exporter. She was originally working on it in Maya’s MEL scripting, which would make it compatible with all versions of Maya.

However, after encountering some problems, she is now coding it in Python. This means the exporter will only initially work with versions of Maya supporting Python  (version 8.5 onwards). It may be that once this work has been finished, Aura hopes to be able to go back and complete the exporter in MEL for older versions of Maya.

Mayastar Update

Cathy Foil will have an update for Mayastar appears shortly. When the .ANIM exporter is available (above), it will be folded in to Mayastar, although it is not exclusively for Mayastar.

Splitting the Avatar Shape into Different Elements

This was suggested some time ago as a possible Bento follow-up as a means of making it easier for users to mix and match heads and bodies by allowing different underpinning avatar shapes for both, which could be worn simultaneously. This was seen as particularly useful for users who are uncertain about customising their form using the sliders, or where creators provide No Modify shape with their head or body product, limiting the suer’s ability to modify one or the other. N definitive proposal has been put together on how this might be achieved.

Supplemental Animations

This was also the subject of early Content Creation meetings with Vir as a possible Bento follow-on project. The idea is to allow “supplemental” animations to run alongside the animation states keyed by llSetAnimationOverride(), effectively allowing them to play together, rather than conflicting with one another as is the case at the moment. This is still be considered, but no work has been carried out as yet.

Next Meeting

As Vir is out of the office in week #11, the next Content Creation meeting will be on Thursday, March 23rd, 2017 at 13:00 SLT.

Fantasy Faire 2017: of regions and registrations

Via Fantasy Faire

Fantasy Faire 2017 will open to the public on Thursday, April 20th and run through until Sunday, April 30th, inclusive.

The largest gathering of fantasy designers, enthusiasts, role-players and performers in the virtual world, Fantasy Faire offers eleven days of shopping, live music concerts, DJ parties, auctions, hunts, Literary Festival, dance and theatre performances, fantasy art, events and role-play – all in aid of the American Cancer Society as a part of Relay for Life of Second Life.

2017 marks the ninth anniversary for Fantasy Faire, and the event this year will be held across fifteen regions, each offering a unique environment which can be explored and enjoyed through the event. These are split between ten themed worlds dedicated to fantasy and commerce, and five worlds to connect them through entertainment and more.

The ten commerce-centric worlds are:

Chaddul Ro  by Searlait Nitschke: “An outpost of the orcs of Chal Khizzur, Chaddul Ro stands on the edge of their territory. In the centre of the outpost there is a beacon, rising above upon a tower guarded day and night by the orcs. It stands for strength; it stands against anyone who would douse it, a symbol to be seen to guide those from outside the protective barriers and walls back home. For the survivors that seek refuge from battle. It is believed that as long as the fires of the outposts are kept lit that there is always hope, sanctuary to be found and that the tribe remains strong.”

Dawn’s Promise by Marcus Inkpen and Sharni Azalee: “A secret place between times where the old becomes reborn into the new. Majestic crumbling ruins dissolve into a sea of glorious foliage. A place where the lost energies of the past are converted into new life. Springs of life-giving water overflow. Flower petals and creative energy float on the breeze. This is the space between the exhale and the inhale. Full of hope and promise.”

Fantasy Faire 2016: Lucentia by Marcus Inkpen and Sharnee Azalee

Egregore by  Mayah Parx: “A fantastical thought form of serene darkness immersed in light, a place where expected purpose is relative and surrealism casts it shadow across the land, inhabited by egregors this fantastical place is born of the collective phantasmagoria of its people.”

Fallen Sands by Sweetgwendoline Bailey and Eldowyn Inshan:Steampunk in a desert landscape where the Orient and Arabia via for dominance. Exotic plants of alien origin turn the sands into an oasis of life where the turquoise water is the treasure of fountains and the infinite pearls of tan fall to mark the passage of time in this eternal city.”

The Hill by Kilik Lekvoda: “A peaceful and beautiful village built into the rolling hills surrounding a small lake. Breathe in warmth, peace, and maybe a little pipe smoke, A place where friendships sprout as readily as the mushrooms beneath leafy green trees.”

Mudrana by Alrunia Ahn and Luna Barak: “Everyone in Mudrana, the land of the lilypad, praises the godfrog – the legends tell that once the godfrog falls asleep, the pond dries out, and everything dies. The frogs of Mudrana therefore croak and sing for their god to keep it awake to preserve the world from death.”

Raven’s Perch by Kaelis Ember and lrriven: “A Gothic dream in pale hues dotted with the tears of roses. A fairytale with thorns.”

The Rose by Alia Baroque: “In the Garden of senses silent footsteps echo through rich vaults of opulence and decadence, searching for the perfect spot where a stolen kiss can be unseen and languid murderous thoughts hidden behind a mask. This Rose blossoms in April through your gaze that tells her how beautiful she is.”

Fantasy Faire 2016: the Golden Delta by Alia Baroque

San Mora by Jaimy Hancroft and Eowyn Swords: “Once the centre of pharmaceutical greatness, San Mora is now a ruin of its former self. Quarantined at the outbreak of a deadly contagion of its own making, the population was left to survive the best they could. Without law and order the city descended into chaos. The fires have long since burned out, and the city is being reclaimed by a hostile Nature. But all that is silent is not necessarily empty. There are still those who roam among the ruins of San Mora.”

The Spirit Pool by Kayle Matzerath:”Since the beginning of time, The Spirit Pool has served as a resting place for weary adventurers and lingering souls that are not quite yet ready to cut their ties to the physical realm. Mermaids and other seafolk use the pool for gatherings and a constant flow of visitors keep it a popular place for trading.”

Fantasy Faire 2016: Breeze by Kayle Matzerath

The five connecting worlds will comprise:

  • Fairelands Junction by Saiyge Lotus: the heart of the Fairelands, the world where the veil between the worlds is thinnest, the Portal World to the others, the First Link of the Chain.
  • Opal Flight by Haveit Neox and Lilia Artis: the arts and entertainment region
  • Morbus by Kilik Lekvoda and Kayle Matzerath: the Fairelands Quest region
  • Kakushi Pasu by Lokii Violet: the Literary Festival region
  • Anansi (Beq Janus and Polysail: the Worldling Cradle – “This year the Fairelands bring the dream seeds with them, the outfits and shapes that they might have taken on, but did not. For now. Worldlings are Fairelands that could have been, Fairelands that might still be.”

Registrations

  • Registrations are now open for merchants and creators
  • Blogger registrations will open on Thursday, March 23rd.
