The orange splines running through the biped have turned yellow. These
are deformation splines, which deform the mesh as the spline moves.5 Select the deformation spline running along the biped's left forearm to
display the associated envelopes.Notice that each biped part has two envelopes, an inner one (red) and
an outer one (purple). Some of the vertices near the opening of the glove
are outside the outer envelope boundary. These vertices won't be affected
at all by the biped's lower arm unless the envelope is enlarged.6 In the Blending Envelopes rollout, in the Envelope Parameters group,
increase the Radial Scale parameter to 2.0.
The vertices at the opening of Dr. X's glove are now within the envelope.682 | Chapter 5 Character-Animation Tutorials
