I can safely tell, that rigging for SL actually its quite painful with the 4 bones per vertex limit. I do all the rigs for Blueberry mainstore. There is something else that everyone is missing already. Wouldnt it be easier to simply implement translations on bones through BVH and do the conversion on SL servers as we have been doing the whole time? Why to complicate something that should be simple from the begining? I am really glad with this feature but we have to get it totally done or not, we cant have it half finished. All we have is blender in which case you force users to buy avastar tool to be able to export that format. Not to mention that there is no official support for anim files. Yeah they are cool and stuff but Im tired of having to use "hacks" and workarounds for something that should be there. I have yet to test how well positioned those bones are in relation with the head at time to make human heads in non custom avatars but I think we could really end all this debate and future problems if you guys simply implement bone translation animations within the common BVH files. Since SL only allows using one, it would mean that wearing this head would shrink your back to the default bone position on the whole body, not just the head, making it impossible to wear a mesh head with joints offset.
Right now, joints offset overlaps one to each other at time of wearing meshes with them. We would need to upload the said head with custom joints which wouldnt be a big issue unless you want everyone to have the same heigh all over SL. lets say we move the bones back enough to the head where those rotations would be translated similar to translations. You cant rotate lips to make expressions, that would be totally messed up but, ok. Its a fact, and everyone involved a bit in 3D knows, that rotations on bones are useless at time to animate facial expressions. Lets say someone makes a new mesh head for SL (it will surely happen). It have been said already how important bone translation is at time to do facial expressions but I think that guys didnt really took something into account at time to remove them. Ok I have a very important question for you.
