I have been working on a facial rig in 3D Studio max. I have always been a Maya user and have taken up 3DS Max recently. Now there was an option in maya called Clusters which was very useful. All I have to do is cluster a set of vertices and paint some cluster weights and parent constraint it with another object and get a control (like the control for inflating my character's cheeks). I am pretty surprised I cannot find any way to cluster vertices in 3D Studio max. Please help me out. I know using Morph targets is a way but I want to know the equivalent procedure in 3DS Max for Cluster controls in Maya.
