WithInitialSkeletalPoseturnedon,checkthat
theenvelopesencloseallareasofthemesh.Ifyou
turn off Initial Skeletal Pose, the character adopts
its animated position at the current frame. Use
an animation that stretches the character around,
such as a run or dance motion. Find a frame
where the envelopes need adjusting, and edit the
envelope parameters. Changing the envelopes
w ith the character in an animated position will
always reference the Initial Skeletal Pose.
These are some frequently encountered problems
with the default vertex assig n ment:
•Verticesthatdon’tfollowtheskeleton.
To correct this, increase the Radial Scale of an
envelope ’s outer boundary.
• Vertices at joints get pushed or dented in.
Too many envelopes might be affecting these
vertices. Try reducing the Radial Scale of the
inner bound, and reduce the Overlap values of
the links on both sides of the joint.
• Bending appears too linear or broken at the
joint.
Increase the envelope’s outer Overlap value
toward the link on the other side of the joint.
Some further adjustments are described in the
“Procedures” section that follows.
Note: An envelope does not need to enclose Patch
tangent handles. It needs to enclose only the patch
vertices. This relieves you from having to scale
the envelopes to a large size to encompass tangent
handles.
