Problem with imported morph targets

i imported anobject with morph targets made in 3ds max to ue4. the deformation works, but when demorming theres a problem that atifacts apeare in shape of out of place vertices. can anyone suggest a solution to this problem? it would be reatly appreciated!

Can you post a picture or gif? Also post an image of your import settings for the mesh and morph targets.

Any answer on this? I am experiencing the same issue. Blendshape looks perfect in Maya, then deforms incorrectly in UE4
