Project Bento User Group update 17 with audio

Project Bento – extending the SL avatar skeleton

Project Bento – extending the SL avatar skeleton

The following notes and audio were taken from the weekly Bento User Group meeting, held on Thursday, June 30th at 13:00 SLT at the the Hippotropolis Campfire Circle . For details on the meeting agenda, please refer to the Bento User Group wiki page.

Note that this update is not intended to offer a full transcript of the meeting, nor does it present the discussion points in chronological order. Rather, it represents the core points of discussion, grouped together by subject matter were relevant / possible, whilst maintaining the overall context of the meeting.

Bento Project Viewer and Moving Forward

The project viewer updated to version 5.0.0.317134, on Thursday June 30th. This update includes small tweaks to the avatar skeleton file, but no structural changes, and provides fixes for:

  • SL-426 missing string for left pec, right pec attachments
  • SL-398 issues with system eyelashes
  • MAINT-6380 vertical flicker with some mesh avatars.

With the exception of the facial bone / slider work (see below) the focus is very much on getting the viewer to a release candidate status, and the project as a whole released. The emphasis with the viewer is on fixing Bento specific bugs, rather than viewer bugs which pre-date project, together with anything which has a major impact on the project as a whole. To this end, a request has been made that anyone who has found an issue or problem they have not reported to either raise a bug report and / or raise it for discussion in the Bento forum thread.

Height Issues / Ground Sits

As noted in my Bento #15 report, there are still some issues around avatars standing on / in / over the terrain when seen from different viewers (a person can appear to be standing on the ground in their own view, but knee-deep in the ground to someone else).

The issue appears to lie it the complexity of the information that is being handled for the avatar, and updates between the simulator and viewers not necessarily arriving in the right order, and Vir hopes the Lab will be able to dig into things some more in the hope of improving how the calaculations are handledthem out.

Facial Bones and Sliders

The forum thread discussion on the facial bones and sliders (see my Bento #16 update) has been continuing. A proposal, as requested at the time, has been put forward, and the promised test viewer was made available on June 27th, together with three new test skeletions (bento human male, bento human female and bento angel). See also Vir’s forum thread post for more information.

Matrice Laville has been trying to implement many of the suggestions put forward on the issue, and ideally the Lab would like to get all suggestions / changes wrapped up by the end of week #27.

Jaw Angle Slider

In terms of the jaw bone angle slider in particular, there was a further healthy discussion over where the problems lay and how best to deal with them. For clarity, the audio of the discussion is given below.

Scaling Wings and Tails to Avatar Height

Currently, the wing and tail bones are not adjusted when changing an avatar’s height via the appearance sliders.  This is because the bones can be re-purposed for other uses, and having them automatically adjust according to adjustments made to an avatar’s height may not always be optimal.

It has been suggested that the hind bones and wings should have their own sliders, but this has been considered outside the scope for Bento, where the emphasis is enabling the existing sliders to be used with the Bento bones as and where they are deemed particularly useful.

In terms of the wings and tail, the suggestion is that they not be hooked into the height slider, but are left as is to allow for the possible addition of dedicated sliders into the avatar LAD file at some point in the future.

Other Items

Pile-on Test

The meeting was abbreviated to allow for a pile-on test to check simulator performance and region crossings with large numbers of avatars. The results will likely be reviewed at the next meeting.

Avastar 2.0 Alpha 3 Release

The Avastar team have issued an alpha update specifically for Bento. Full details can be found in the release notes for the changes and known issues.
