Hi,

I'm trying to generate new facial AUs for ChrBrad. Currently I'm doing this in Blender, and export the animations as bvh. Whole body animations seem to play back fine, but face animations do not seem to work.

Can you send it/post one so that I can see if there are any problems with the file?

this one works for the whole body:

this one (my attempt at doing AU15) doesn't do anything:

Thanks!

I don't see any significant data on the face joints for your AU_15 animation. I've attached a video. Is this what you see as well?

I gave up on facial animations via bvh; following the instructions form here: https://groups.google.com/forum/#!searchin/vhtoolkit/face$20animation/vhtoolkit/6ZH4gfeF5Ok/Pub4yJqUWEQJ
I've had some success generating fbx->skm Action Units
