welcome to the fourm by the way...........Are you using a biped or one of your own models, also did you use the script that comes with max or did you rig yourself. about the weights I did not put all my body parts to one weight. your head is heavier then your hand. I hope anyhow

. yeah I had a great deal of problems till I ran that script on my bipeds.
I myself have been playing around with rag doll alot.
