Unity 4.3 had support for shapekeys and imported them from the .blend files.
On youtube are some tutorials showing how to create models with shapekeys in blender 2.68 and bring them to Unity 4.3.
But it somehow does not work with Blender 2.72 and Unity 4.6.
Has someone managed to use blendshapes with Unity and a Blender Version above 2.68?
I thought maybe its broken because of the new fbx exporter. Or is it a Problem with Unity?
