Thank you for the resposes, luckily I am not trying to enable these physics on a parental tree, but rather a tank with many moving parts.

Heelx, I was a little confused by your respose as well, are you suggesting to create another completely seperate bone structure to enable physics control on, aside from the player controlled skeleton which I currently have effecting the mesh animations? It made sense for me to do them all in one fell swoop.
