Server Deployments, Week 3 – Recap

As always, check the server deployment thread for any updates.

On Tuesday, January 19th, the Main (SLS) channel received the server update package previously deployed to the three RC channel. This comprises:

  • Feature Request: llGetObjectDetails() constant OBJECT_TOTAL_INVENTORY_COUNT – when targeting an object, OBJECT_TOTAL_INVENTORY_COUNT will return the total of all inventory types in each link of the linkset. See BUG-10575 for further details
  • Feature Request: llGetObjectDetails() constant OBJECT_PRIM_COUNT – provides a means to get a worn attachment’s prim count (rather than just returning 0).  See BUG-10646 for further details.
  • Simulator crash fixes.

On Thursday, January 21st,  three RC channels received a new server maintenance package comprising a simulator crash fix and a further feature request: llGetObjectDetails() functionality to get the parent_id of any task in the region (OBJECT_REZZER_KEY). This returns the parent_id of any task in the region. If the object came from an object rezzer it returns the ID of the parent object, while If it was rezzed by an avatar, it returns the agent ID of the avatar. The function only works for those objects rezzed in-world after the code deployment (objects in-world prior to deployment will return NULL_KEY).

SL Viewer

The HTTP updates Vivox RC viewer updated  to version on January 19th, while January 20th saw the Quick Graphics RC viewer updated to version, and the Project Bento (avatar skeleton extensions) viewer updated to version

Project Bento

I missed the greater part of the Project Bento meeting on Thursday, January 21st, so my apologies for not having a full report.

Deformed Avatars: The lab is still asking for examples of avatars deforming as a result of using a mesh uploaded with different joint positions. If people have examples, Vir Linden requests that both the .DAE file and a copy of the mesh model are forwarded to him so that the Lab can test items for themselves.

Elizabeth Jarvinen (polysail), also points to some discussion on the Bento forum threat on how to possibly correct the problem when it occurs. see: here, here and here).

.BVH and .ANIM uploaders: It was noted at the meeting that the .BVH and .ANIM uploader have different capabilities. The .BVH uplaoder is viewed as being not as robust as the .ANIM uploader, although it does include optimisations for animations which are not present in the .ANIM uploader. Oz Linden suggested that it would be nice if both uploaders shared the same level of robustness / capabilities.

Vir pointed out that the .BVH uploader has various optimisations which are not present for .ANIM uploads. So how parity between the two is achieved is unclear. fore example:

  • Is the optimisation code removed from the .BVM uploader or added to the .ANIM uploader?
  • Are the updates server-side, or should they be viewer-side, with the ability to preview animations prior to final upload to ensure they are playing correctly?

It is also open to question whether any such work, were it to be undertaken, would form a part of this initial Bento project.

Bento Bone Survey

I was absent (as noted) when this particular item was discussed, so I may have the details wrong. However, it appears that, as previously reported, the Lab are going to put out a survey asking for creators and animators to indicated their preferred additional bones out of those which have been suggested. The survey is liable to be published via the Bento forum and / or the Bento user group wiki page.

World Makers Filming

There will be a final Bento filming session for the upcoming Drax Files World Makers special on Monday, February 1st. Creators and animators who have examples of content using the Bento skeleton extensions and are willing to take part in the filing should contact Draxtor Despres in-world for further details.

Aditi Inventory Syncing

The code for merging main (Agni) inventories into beta (Aditi) grid inventories is still subject to final testing before being deployed to Aditi. As previously noted in these updates, when this does happen, it will mean that logging-in to Aditi will trigger an automatic merge of your Agni inventory with your Aditi inventory as a part of an overnight (PDT) process. This means that items unique to people’s inventories on Aditi will no longer be lost as a result of their Aditi inventory being overwritten by their Agni inventory (as is currently the case). Once deployed, this update also means that a password change will no longer trigger an inventory sync between the two grids.

Suggestions have been put forward that rather than merging Agni inventory directly into the Aditi inventory structure, the incoming Agni items are delivered to a new top-level folder (perhaps called “Agni” or “Main Grid”) during the merge process, so that people can easily distinguish between unique versions of items they’ve been editing on both Aditi and Agni.

Adobe Flash on CEF Viewers

As has been covered in this blog and others, the Second Life viewer, version 4.0.0+, and all v3 TPVs using that code now makes use of the Chromium Embedded Framework for supporting rich media, including Adobe Flash.

However, for the latter to work with the viewer, it requires a specific version of Flash to be installed on your system. For those interested, Jeremy Linden has provided a knowledge base article on what needs to be installed for the official viewer, and how. With thanks to Willow Wilder for the pointer.
