Hey,
When I export a ball with a morph target from Maya using FBX 2012, the ball morphs and rotates just fine. But when using any newer version of FBX, the ball doesn’t morph anymore, it just rotates… All files were imported to Unity and worked fine.
Which versions of FBX are supported by UE4? I had to enable the material to support morph targets to avoid an error in the animation preview.
