Seanchai Library Comes to Holly Kai Park

Seanchai Library, Holly Kai Park

It’s time to kick-off another week of storytelling in Voice by the staff and volunteers at the Seanchai Library. As always, all times SLT, and events are held at the Library’s new home at Holly Kai Park, unless otherwise indicated.

I’m absolutely delighted to see Seanchai at the Park, becoming part of our family and helping to expand our support of the arts in second Life. The familiar programme of weekly storytelling from Seanchai will continue via their new headquarters at the park, while they’ll also be able to run special events using the park’s grounds and our sky platforms.

So, without further ado, here’s the first week of events from Seanchai Library.

Sunday, June 25th, 13:30: Tales of Ships, the Sea and Other Wetness

Join Library staff and guests in a celebratory 90-minute event to launch their new season at their new home at Holly Kai Park .

Monday, June 26th 19:00: The Book of Skulls

Gyro Muggins reads Robert Silverberg’s novel.

Four friends, college room-mates, go on a spring break trip to Arizona: Eli, the scholar, who found and translated the book; Timothy, scion of an American dynasty, born and bred to lead; Ned, poet and cynic; and Oliver, the brilliant farm boy obsessed with death.

Somewhere in the desert lies the House of Skulls, where a mystic brotherhood guards the secret of eternal life. There, the four aspirants will present themselves–and a horrific price will be demanded.

For immortality requires sacrifice. Two victims to balance two survivors. One by suicide, one by murder.

Now, beneath the gaze of grinning skulls, the terror begins. . . .

Tuesday, June 27th 19:00: The Ordinary Princess

Faerie Maven-Pralou reads MM Kaye’s 2002 novel.

In true fairytale style, the seventh princess is blessed with gifts by a host of fairies, but as her father fears, it goes wrong and one slightly bitter fairy ‘blesses’ her with ordinariness.

So no golden curls, stunning beauty and sublime grace for Princess Amethyst Alexandra Augusta Araminta Adelaide Aurelia Anne. Her dark hair and freckles make Amy (no ordinary princess can be called anything else) stop every suitor from pursuing her. She decides to run away and make her own life, away from boring princes and a confined life.

A life in the forest is bliss, but eventually Amy realises she will need some money, and must find work. So it is that she becomes the fourteenth assistant kitchen maid at a neighbouring palace. And there  – much to everyone’s surprise – she meets a prince just as ordinary (and special) as she is!

Wednesday, June 28th 19:00: The Girl Who Drank the Moon

Caledonia Skytower reads Kelly Barnhill’s 2017 Newbery Medal winner.

Every year, the people of the Protectorate leave a baby as an offering to the witch who lives in the forest. They hope this sacrifice will keep her from terrorizing their town. But the witch in the forest, Xan, is kind and gentle. She shares her home with a wise Swamp Monster named Glerk and a Perfectly Tiny Dragon, Fyrian.

Xan rescues the abandoned children and deliver them to welcoming families on the other side of the forest, nourishing the babies with starlight on the journey.

One year, Xan accidentally feeds a baby moonlight instead of starlight, filling the ordinary child with extraordinary magic. Xan decides she must raise this enmagicked girl, whom she calls Luna, as her own.

To keep young Luna safe from her own unwieldy power, Xan locks her magic deep inside her. When Luna approaches her thirteenth birthday, her magic begins to emerge on schedule–but Xan is far away. Meanwhile, a young man from the Protectorate is determined to free his people by killing the witch. Soon, it is up to Luna to protect those who have protected her–even if it means the end of the loving, safe world she’s always known.

19:00: Moby-Dick Part 1

“Call me Ishmael.” So begins one of the greatest works of imagination in literary history, Herman Melville’s magnificent Moby-Dick or, The Whale.

As Ishmael is drawn into Captain Ahab’s obsessive quest to slay the white whale Moby-Dick, he finds himself engaged in a metaphysical struggle between good and evil. More than just a novel of adventure, more than a paean to whaling lore and legend, this is a haunting social commentary populated by some of the most enduring characters in literature.

The crew of the Pequod, from stern, Quaker First Mate Starbuck, to the tattooed Polynesian harpooner Queequeg, are a vision of the world in microcosm, the pinnacle of Melville’s lifelong meditation on America.

Written with wonderfully redemptive humour, Moby-Dick is a profound, poetic inquiry into character, faith, and the nature of perception. Join Shandon Loring as he commences a reading of this magnificent tale.

 

21:00: Seanchai Late Night

Contemporary science fiction with Finn Zeddmore.

The meeting is chaired by Vir Linden, and agenda notes, etc, are usually available on the Content Creation User Group wiki page.

Audio extracts are provided within the text, covering the core project LL has in hand. Please note, however, that comments are not necessarily presented in the chronological order in which they were discussed in the meeting, but are ordered by subject matter.

Server Deployments Week 25 – Recap

As always, please refer to the server deployment thread for the latest updates.

  • On Tuesday, June 20th, the Main (SLS) channel was updated with a new server maintenance package (#17.06.12.327066), containing fixes to help with the caps (capabilities) router (see here for details).
  • On Wednesday, June 21st, the RC channels were updated as follows:
    • BlueSteel and LeTigre should receive the same server maintenance package (#17.06.19.327206) containing internal fixes
    • Magnum should receive a server maintenance package (#17.06.19.327192) intended to fix BUG-100830 (“HTTP_CUSTOM_HEADER no longer works on RC 17.06.13.327111”) and BUG-100831 (“Lelutka Simone bento head spits a script error when attached on 17.06.13.327111 regions (Magnum & Cake)”).

Animated Objects

Vir has been trying to get animated objects using the avatar skeleton to scale in a reasonable way and that linksets are correctly referencing the same skeleton, and things are handled corrected when they are attached or detached. He’d also be interested in hearing from makers of the “current generation” of pets on how they work – how do they maintain ground contact, how they follow along, how the physics is getting managed, so that he can look into trying to make animated mesh objects operate in a compatible manner.

So, if you are a pet maker and can help Vir in this, please either attend the Content Creation User Group meetings, or contact him directly.

Attaching Animated Objects to Avatars and Avatars to Animated Objects

One of the popular aspects of pets today is the ability to attach them to an avatar (so you can carry them, have them sitting on your shoulder, etc), and this is seen as a potentially important aspect of animated mesh. However attempting to do so does present issues, as it would mean linking two avatar skeletons in some manner, something that is not currently possible. While there are some potential ways this could be done, it could add considerable overhead to the existing project, and also brings potential challenges with it – such as ensuring an attached skeleton is correctly oriented, determining the potential performance hit, etc..

Similarly, BUG-100864 suggests a means of going the other way – linking an avatar to an animated object – such as being able to walk up to a free-roaming horse on a region and being able to mount it and ride it, for example. However, this also raises some of the same concerns.

While not ruling either out, Vir is focused on bringing forward a relatively basic means of animating mesh objects using the avatar skeleton, one which can offer a series of potential uses whiles conceivably allowing existing mesh creations (such as pets) to easily be converted to use it. As such, he sees it as a foundation project, which can then be expanded to incorporate other capabilities in the future, rather than trying to pack everything into a single project which could run the risk of very long development times or becoming overly complicated with all it is trying to achieve right from the start.

Baked Textures on Mesh

Work is still focused on the baking service infrastructure updates required to support baking textures on mesh avatars. These are quite extensive, involving changes to the underpinning tools, the servers (including updating Linux), and so on.

Rigging To Attachment Points

There has been some confusion of late as to whether rigging to attachment points is allowed or not. From the Lab’s perspective, it is not allowed for uploaded since the introduction of Bento, but should still work for legacy items. However, what appears to be a server-side glitch in the last couple of weeks seems to have exacerbated the confusion.

Vir’s recommended rule-of-thumb for TPVs to test against the Lab’s official viewer and ensure behaviours match, otherwise confusion could occur down the road once the current glitches have been corrected. To help with matter, he’s going to refresh his mind on what limitations are enforced server-side, and hopefully bring a list of them to the next meeting to help TPVs ensure they are following the requirements in order to avoid future problems.

Other Items

Mesh Body Dev Kits / Clothing Making / “Standardised” Mesh Avatar

This topic took up the core part of the meeting, and as such, the following is an attempt to precis the core points into a readable summary

At the moment, all mesh bodies in Second Life are unique to their creator, utilising their own core shapes and skin weightings, which have a considerable amount of IP bound up in them. Because there is no available “standardised” mesh model available in Second Life, it means that the body creators need to provide developer kits to mesh clothing and attachment makers, which include this core information –  skin weights (in Blend or Maya or DAE or OBJ files) for rigging clothing and the shapes, which potentially makes it very easy for someone to create their own avatar bodies.

To try to reduce this risk, mesh body makers tend to have license agreements clothing makers are required to agree to, and by sometimes limiting who may or may not be deemed eligible to obtain such a kit.   This has  caused some friction / frustration in the cloth making community.

One suggestion put forward to help reduce fears on the part of mesh avatar creators and allow clothing makers more readily support avatar body brands, was that avatar makers should perhaps consider offering only the body shape to clothing makers – and then offer a fee-based rigging service to clothing makers. This would remove the need for avatar makers to give out their skin weight files, offer them a revenue stream and allow clothing makers more equitably create clothing for the more popular mesh bodies.

While there are no projects on the roadmap aimed at the SL avatar system, two other ideas were put forward which Vir agreed, could be worth consideration down the road:

  • One is a suggestion that LL look to emulate the ability in Maya and Blender to copy skin weights from an avatar model to an item of mesh clothing by running an algorithm to match the weighting from the avatar to the nearest vertices in the clothing. This would allow the clothing to fit almost any mesh body “automatically”, removing the need for clothing makers to specific weight their clothing to each of the mesh bodies they wish to support.
  • The development of a news “SL mesh avatar” designed to operate alongside the existing system avatar (so no content breakage for those preferring to continue using the current system avatar). If this avatar had a sufficient density of vertices, it offers two potential uses:
    • Mesh body makers could use its weightings with their custom shapes to produce individually unique mesh bodies, but which all have a “standardised” set of skin weights, reducing the amount of work involved in creating them (or they could continue to use their own custom skin weights if they wished
    • It could offer clothing makers a single source of skin weights for clothing, simplifying clothing making, which – if combined with the vertices matching algorithm mentioned above – would help ensure the clothing “fits” custom weighted mesh bodies.

The vertices matching algorithm idea might be the more difficult of these two ideas to implement – were either to be considered. However, the development of a mesh avatar that could exist alongside the system avatar could have a lot of merit and help “standardise” the more technical aspects of mesh avatars without impacting their individual shape / look.

Further, as mesh objects can support multiple UV sets, it would be possible for such an avatar to use the legacy UV map use to define the texture spaces on the three parts of the system avatar (thus allowing it to use existing skins, etc), or it could support more “advanced” UV maps (so skin creators could finally design skins with two arms, rather than having the one arm “mirrored” on the avatar, as is currently the case.

Why isn’t Scaling Bones by Animations Allowed?

Scaling bones using animations has never been supported in SL, although Vir isn’t clear on why (and pseudo bone scaling via animations has been possible through attachment point scaling or animating the point positions). However, one of the things that makes designing avatars harder is multiple ways to manipulation and aspect of a bone, because of the potential for conflicts. An example of this is bone translations, which can be affected by both animations and the shape sliders, and so can cause issues.

However, during the Bento project, the advantages of allowing translations through animations was such that the Lab opted to permit it, even allowing for the potential for issues. As scaling bones through animations could bring about a similar level of possible complexity to avatar design (as bones can obviously be scaled via the sliders, this could be the reason scaling bones via animations hasn’t been supported. Currently, this is unlikely to change, if for no other reason it would require a change to the animation format, which currently has no means to interpret bone scaling.
