In this tutorial, I’m going to show you quickly and easily how to apply Ragdoll physics to your enemy characters.
IMPORTANT!!!
At 2:22, I mistakenly click the character’s "Capsule Component," but you actually need to select "Mesh (CharacterMesh)." After that, you can safely change the "Collision Preset" to "Ragdoll."
