I imported my stick figure SK mesh with unreal skeleton. Simulate worked fine. Playing animation was fine. But when I blend physics with animation the arms have some weird deformation. (See pictures below)
Somebody please help. Still struggling with this. Any sort of change would be nice 
I think I figured it out. There are bones dedicated for twisting control in UE4_Mannequin SK and I didn’t pay much attention to them and maya bind skin to them automatically.
