Hello. I am starting to learn how to use Unreal Engine 4 and i come to a problem. I have human NPC with animation where he leaps backward and falls on the ground. When he falls the NPC will change to Ragdoll state. I want only chest to have enabled physics and nothing else but i can only make it so whole body has physics simulated or upper half of body including arms and head. Is there a way to constraint a position of arms and head to be in one place and only to intteract with chest ?
