appropriately. This is accomplished with the
Trackgroup Filter dialogs (biped and non-biped
objects).
The Trackgroup Filter dialog for biped objects.
The Trackgroup Filter dialog for non-biped objects.
When a trackgroup is created, it is g iven one Layer
track by default. However, you can add more
tracks to each trackgroup, ma k ing it possible
to mix motions for each set of body parts. For
example, you could create a trackgroup for the
arms, and have two t racks within this trackgroup.
Then you could put two completely different sets
of motions on each track, and use weighting to use
one t rack or the other at different times during the
motion. See Adjusting Track Weight (page 2–619).
