Envelopes and Vertex Assignments
Envelopes
Envelopes are Physique's primary tool to control skin deformation. Envelopes
define an area of influence about a single link in the hierarchy and can be set
to overlap adjacent links. Vertices that fall in the overlap area of the envelopes
are weighted to produce smooth blending at joint intersections. Each envelope
comprises a pair of inner and outer bounds, each with four cross sections.
Envelopes
Deformable and Rigid Envelopes
There are two envelope types: deformable and rigid.
■ Deformable envelopes influence vertices they encompass to follow the
deformation spline created through the hierarchy. Only the vertices
encompassed by deformable envelopes can be affected by bulge angles or
tendons.
