Importing Biped from 3DS Max to unreal with interesting results, please help


so I’m currently trying to just do some simple animation, I have mocap data, that works fine in 3DS Max when i attach it to the biped rigged character however when I import the character with the skeleton into Unreal it seems to lose all sense of where the bones are meant to be.

Here you can see the head bone is nowhere near the head, all of the bones are like this once imported into unreal, I’m an environment artist but my current uni assignment requires we animate a character.

Any help would be appreciated!
