Yeap! I was a "jester" in another life... But, My bro did make a plug-in that's partialy working for Max, that does just that! So, far it crashes on meshes that have to many vertices... But, who knows??? Maybe the folks at Curious Labs have already sloved that for poser5!(Crossing fingers!) Basically, how Marco went about it is simply create what's called a "matrix" in programming, that keeps track of vertices or faces for "predefined" groups. There's already a good explanation of the priciples & algorythms invlolved available in 3D Math books... The problem with doing it with the vertices, is that it gets too complicated for even High-End PCs(p4 1.6ghz) too handle! So, the only "Viable" aternative is with faces or groups of them... Anyhow, Back to "posing"... Tada! Anik
