I have created a sample biped with running motion loaded (a bip file). The problem is that the motion will move the coordination of the model. I want it to perform the whole chain of action at a fixed coordination. Is there any good way to solve this problem? I am using 3dsmax 7.

Yes there is ... I believe that there is a check box somewhere with the biped.
Sorry that I cannot be more precise. I just know that it is possible.

Cheers

Oh thankyou, I just found that little box.
