Two envelopes appear around the arm link. The vertices inside the
envelopes are influenced by the bone. The inner red envelope indicates
the area of most influence. The link's influence decreases until it reaches
the purple outer envelope. Vertices outside the envelopes are not affected
at all by the bone.
Vertices affected by the currently selected envelope turn various colors
to show they are influenced by the envelope.
The radius of each envelope can be changed with the Radial Scale
parameter. Increasing the radius enlarges the envelope to encompass
more vertices, increasing the number of vertices affected by the bone.TIPTo see the envelopes' influence in color in a shaded viewport, turn on
the Shaded option in the Blending Envelopes rollout > Display group.5 In the Blending Envelopes rollout > Envelope Parameters group, increase
the Radial Scale parameter until all the vertices in the sleeve pop into
place.930 | Chapter 5 Character-Animation Tutorials
