The ASCII exporter can export shape keys (although, not bone-less shape key animations), which Unity imports as BlendShapes. The binary FBX exporter does not appear to export shape keys.

This is TODO, not bug - and for sure not a 2.71 target…

@Moguri I would need a simple FBX file from max or so with one or two shapekeys in it… I suspect shapekeys are no more embedded in mesh as they were in 6.1 (at least, they have their own class in FBX SDK).

I do not currently have access to Max or Maya, so maybe we'll need to see if we can get a sample from the community?

@Moguri ah, forgot to followup here, using FBX converter I was able to get an 7.3 with shape keys, so now I know how they are layout, no more need for that.

Just need time to code this (it’s nearly as complex as armatures/skinning :/ ).

Code is in master now (relative shape keys only, for now!, 0abd36f1ec and 59ff66fa7a).
