The following picture is what happened when I retarget UE4 manequin animation to Countess skeletal mesh.
The result is funny. The reason behind this distortion as I found out is because different hip bone design between 2 skeletal mesh. In fact, all Paragon hero follow this hip bone design while market assets tend to follow UE manequin design.
That’s kinda sad to know. Did you guys have this problem yourself, and is there anyway to overcome this?
