Simulated Physics ignores collision

Hi, I have parts of my character that I skinned to special bones and that I want to simulate physics. I have set up a Physics asset for my character. When I simulate in the Physics editor everything is fine, but when I simulate physics for the one bone inside my character blueprint it seems as if it ignores the collisions of the other not simulated bone volumes and just hangs down. How would i go about fixing this?
Thank,

I figured it out, i had to enable ragdoll collision on my mesh in the character blueprint.
