On Tuesday, May 3rd, the Main (SLS) channel received the same server maintenance package originally deployed to the three RC channels in week #17, comprising a crash fix and minor internal improvements.
There will be no deployment to the RC channels on Wednesday, May 4th, and no scheduled restart of simulators on that channel.
SL Viewer Updates
The two release candidate viewers currently in the release channel were updated at the end of week #17:
The current Maintenance release candidate updated to version 4.0.4.314579, dated April 28th
The Quick Graphics release candidate updated to version 4.0.4.314426, dated April 26th.
This means there has been no promotion of an RC to de facto release status, while the project viewers have not been updated, leaving the complete list of remaining official viewers as follows:
Current Release version: 4.0.3.312816, dated March 23rd and promoted on April 1st, formerly the HTTP / Vixox RC viewer
Project viewers:
Project Bento (avatar skeleton extensions), version 5.0.0.313876, dated April 15th
Oculus Rift project viewer, version 3.7.18.295296, dated October 13, 2014
Obsolete platform viewer version 3.7.28.300847 dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.
Avatar Complexity
There are still some issues yet to be resolved with Avatar Complexity which is why this viewer is currently not progressing towards a release status at present. One of these is avatars which should render as solid colours (or “Jelly Dolls” as the popular term for them is now) or imposters are invisible.
This has been a long-standing issue (see BUG-10330), which has proven hard to reliably reproduce, and has had a number of theories attached to it. Recent testing has suggested one of the causes is a possible conflict between the viewer trying to render avatars as Jelly Dolls whilst trying also to account for any alpha mask applied to the avatar with all the layer check boxes ticked. This is possibly because ticking the alpha mask check boxes result in a “special” UUID being applied. Currently, the precise cause of the issue has yet to reach a consensus opinion, and investigations and tests continue.

The following notes and audio were taken from the weekly Bento User Group meeting, held on Thursday, April 28th at 13:00 SLT on Aditi. For details on each meeting and the location, 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 to Project Bento, grouped together by subject matter were relevant / possible.
Issue Fixes
Partial Joint Offsets
As noted in my last update, one issue facing Bento is in how best to handle defining partial joint offsets – a mesh that specifies the override positions for some of the joints but leaves other joints alone, which would allow different meshes to be mixed and matched to create an avatar look. Currently, the viewer doesn’t handle multiple root bones in a mesh with partial rigging correctly, and to help correct this, Vir Linden has published a proposal for moving forward. Essentially, this would filter out any joints which have a position unchanged from their expected default, even if the mesh claims to use an offset, with only a very small adjustment (0.1mm or greater) is required to have a joint treated as having its own offset.
Offset and Slider Conflicts
Another issue which has been discussed recently is that joints offsets (notably translation offsets) can conflict with adjustments made using the appearance sliders, resulting in adjustments made using the sliders “snapping back” to their original location on leaving edit shape or following a relog or after removing / rewearing the avatar mesh.
An adjustment has now been made so that where an offset has been set for a joint, adjustments made using the sliders which only affect the offset will be ignored, only changes to the scale of a joint (length, height) made using the sliders will work. It is thought that this fix will also address the likes of BUG-11854.
Work in progress: Aki Shichiroji demonstrates a wearable wyvern utilising Bento bones for animation.
It has also been noted that BUG-10991, “[Bento] Mesh rigged to the new joints either partly disappears, collapses or melts when viewing that avatar as an imposter” has not been fixed with the latest version of the project viewer. It will hopefully be one of the issues addressed with the next update.
Next Viewer Update
The above fixes, coupled with other work which has been carried out are regarded as being sufficient to kick-off another update to the project viewer, although there is a further piece of work Vir hopes to include. If all goes according to plan, this should see a new version of the Bento project viewer appearing in week #18 (week commencing Monday, May 2nd).
Animation File Size Limit
Currently, there is a file size limit of 120 Kb on animation files enforced by the back-end servers. With the increased number of bone available for animation. As it is now possible to animate a far large number of joints, some creators have started to find this limit a problem, and a request has been put in for it to be increased (see BUG-11836).
While there is potential for this to be done, it is currently unclear how much the file size limit should be increased. There are also other considerations to take into account, such as the intention for animation assets to be moved to the CDN for better delivery.
If there are specific examples of animation with large file sizes which could be attached to the JIRA as examples, they would be welcomed by the Lab. It has also been suggested that the Lab establish a best practices guide for animations files on the wiki.
This lead to a brief discussion on interpolation and the differences between .BVH and .ANIM animations, with Vir providing background information on how each are respectively handled.
Sliders for Remaining Bento Bones
While many Bento bones – notably those of the face / head – have been tied-into the existing appearance sliders, there are still those which do not have slider support because they would require the development of dedicated sliders. this has been considered outside the scope of the initial Bento work, and it is far from certain it will be taken up in the near-term future, if at all.
Part of this comes down to the added complexity further sliders would thrust into the viewer UI, and also – as Vir explains – because the use of many of the Bento bones is intended to be arbitrary, therefore providing sliders to adjust them may not suit all of the uses to which they might be put, and cause further confusion / unpredictable results when used.
There was no Main (SLS) channel deployment on Tuesday, April 26th.
One Wednesday, April 27th, all three RC channels should receive the same server maintenance package, comprising a server crash fix and some minor internal improvements
Oculus Rift project viewer, version 3.7.18.295296, dated October 13th, 2015 – Oculus Rift DK2 support (download and release notes)
Obsolete platform viewer, version 3.7.28.300847, dated May 8th, 2015 – provided for users on Windows XP and OS X versions below 10.7 (download and release notes).
Alchemy viewer updated to version 4.0.0.37561 (Beta) on April 16th. This is another progressive update, containing a lot of under-the-hood improvements and fixes – notably around rendering – and a new visible update in the form of a client-side animation override capability, modelled after the one most popularity seen in Firestorm.
The update also sees a Linux 64-bit release as well, although going by the comments following the release notes blog post, there appear to be log-in issues associated with the Linux version.
This, and the previous “beta” release are intended to get the team’s own updates in front of users ahead of some major updates which will be forthcoming as Alchemy (as with all other viewers) merge with some significant releases coming down the pipe from Linden Lab (including the Avatar Complexity capabilities and – eventually – the Project Bento updates).
As the AO update is the most visible change with this release, and given I am not a regular Alchemy user (although I find it possibly the best viewer for video capture), the rest of this article focuses on the AO aspect of the update.
The client-side animation override (AO), is intended to replace he need for HUD-based scripted animation overrides, instead driving animations – walks-sits-standing poses, etc – directly through the viewer, thus freeing-up simulator resources. Using one does require a little work in setting-up (but so can HUD-based systems), but you can run multiple animation sets directly from the viewer.
Essentially, the AO system comprises three parts:
The animations you wish to use, which you will need to copy / move from any associated HUD system to your inventory – placing them in a folder within your Animations system folder is often a good way to do this
A configuration note card defining the animation you wish to use. Like configuration note cards found in many ZHAO -based animation overrides (so simply using the note card found within your scripted AO system should work OK), this defines animations by type: stand, walk, sit, etc (you can also manually create an animation set if no configuration note card is available)
The viewer UI elements.
To use the client-side AO, you’ll need to have the animations you wish to used stored within your inventory (not within another AO system) (l), and a suitable note card defining the animations you wish to use with the AO (r)
Once you have done this, you’re ready to set-up the client-side AO system. You can access the AO floater in one of two ways:
By adding the AO button to your viewer toolbar and then clicking on it to open the AO floater
By hovering the mouse over the AO icon at the top right of your screen to display a minimised AO floater.
The latter is actually the easiest, given the way Alchemy have implemented to AO system. Assuming you take this approach, click on the spanner icon in the minimised AO floater to expand it.
The client-side AO floater – minimised (l) and expanded (r)
Now, simply drag and drop the configured animation note card from your inventory to the AO floater. This will cause Alchemy to configure the AO system ready for use, and result in a list of your animations appearing in the floater. At the same time, a set of links will be created in the Animation Override folder in your inventory – do not delete these!
Alternatively, if you don’t have a configuration note card for an animation set, click the + button on the AO system floater, type in a name for your animation set, then drag and drop all of the animations you want to use in the set from your inventory into the AO system floater.
