When I import a cc3 character into unreal, the bones have their positions all messed up. As you can see from the pic. I have been using the default export profiles with mesh only.
I had to bring the model into Modo after exporting out of cc3 with the maya template and then bring it into ue4 to get it working. Also had to tweak the mesh because its not on the ground plane.
The same maya crash is still happening, if I export the mesh out of modo and open that file in maya (cc3 to modo to maya). It is fixed when going cc3.3 to just maya. Zip file attached
