Hi, I am new so I am having a bit of trouble in blender. The thing is I have a basic, rigged human, and a cylinder that is parented to one of the bones using a child of constraint. When I play animations the cylinder follows the bone normally, but when I try to play them in the game engine the cylinder stops following the bone. How do I fix this?

Hello

assign to the cylinder a Vertex Group with the same name as the hand one for example!
Bye
