Maya: Adjust similar skeleton to UE4 Mannequin Skeleton


i have two meshes. One is the ZMech with its skeleton. I have changed the ZMech Skeleton that it is equal to the common UE4 Skeleton.

Here are the pictures:


bindposes are both great, even after adjusting the zmech skeleton.

But when i import the zmech in ue4, all animations are distorted.

Just wanna ask, if someone who is familiar with skeleton and maya, can tell me the workflow to make the mech skeleton compatible with the ue4 mannequin skeleton and its animations.

I would like to keep the bindpose cause it would take so much time to re-weight paint it again.

Thanks in advance

Best regards

I have the same issue. mine works but the body moves like a jelly or something weird.
