Just wondering if someone would be kind enough to advise on my situation. Freaky-Freeky was kind enough to point out the edit membership tool, which on doing a google search I have managed to get to the relationship editor within maya. As you will see with the image below, I have 'skincluster1set' and 'pasted_softmod1set'. I am confused as how to change the 'membership'? How do i connect the various yellow pieces to the bones of the shark jaw in order to make it open naturally? Any help greatly appreciated! [IMG][/IMG]
