Ok . Thanks so much. What i was confused about was that, when i use to export animations our of maya or motionbuilder, it was only the skeleton, and UE4 would import that as an Animation Sequence into the editor. I thought that bones were the only animations UE4 would accept.
To anyone looking for the solution, its pretty simple (also referring to the second link from 's reply).
- import the Skeletal Mesh without animation to set up your character in UE4
- when ready, simply animate the blendshapes in Maya/Motionbuilder (both worked), and export out the animated body and keyframed blendshapes by FBX, include the character geometry of course and the skeleton.
- when importing into UE4, use the set up Skeletal Mesh you already have as the target, import morph targets and animation.
- in persona, you can now see the animated body WITH the blenshapes animated as well.
in conclusion: UE4 is awesome.
