Can I convert a standard armature animation into a vertex animation? I need to be able to do this because I want to export good facial animation from blender into another program as a vertex animation, which it does support. I can’t do it as an armature animation because more than 3 bones share various vertices.
You can convert bone animation to shape key animation using the Animation / Bake Action menu.
Alternatively if the application supports it export to a mesh cache format such as .mdd http://blender.stackexchange.com/questions/45921/how-to-import-mdd-files
instead,what about to convert shapekey animation into bone animation ?
