UE4 Vertex Animation breaks and becomes streaky when parented to animation

Hey,

I have exported a series of fluid simulations from houdini. I have attached them to the character. When the character moves the vertex animation looks like an explosion of streaks. When they’re stationary they play normally.

I have checked bounds, Full Precision UV’s, Local Space and not had any luck.

Has anyone else encountered this problem? If so, how did you solve it?
