Physique is a modifier that when applied to a mesh, allows the movements of an underlying skeleton to seamlessly move the mesh like bones and muscle under a human skin. Physique will work on any point-based objects including geometric primitives, editable meshes, patch-based objects, NURBS, and even FFD space warps. For NURBS and FFDs, physique deforms the control points, which, in turn deform the model. It will attach to any skeleton structure including a biped, 3DS MAX bones, splines, or any 3DS MAX hierarchy.
