Trackgroup
In the Motion Mixer, motions are placed on tracks,
and the tracks are organized into trackgroups.In
other words, each trackgroup is a holder for one or
more tracks. Each trackgroup can be filtered so
thetrackswithinitaffectonlycertainpartsofthe
biped, such as its arms or legs. Every biped in the
Motion Mixer can have multiple trackgroups, each
with its own selection of biped parts. See Adding
Tracks to the Mixer (page 2–607) and Filtering
Mixer Tracks (page 2–612).
Track V iew Hierarchy Icons
The Track View hierarchy, as displaye d in the
Cont roller window, follows the traditional example
of organizational headings in an outline. The
highest levels of the hierarchy represent the main
groupingsin3dsMaxofSound,Environment,
Materials, Render Effects, and Objects. Lower
levels of the hierarchy progress through the
detailsofyourscene,suchasindividualmaterials,
material maps, and map parameters.
Each type of item in the Track View Hierarchy List
is represented by an icon. You can use these icons
to quickly identify what each item represents.
SoundIndicate s ound parameters. 3ds Max
provides only one sound source in Track View.
Material—Indicates material definitions. All
branches below a material definition are part of
that material. Because a m aterial can be composed
of multiple materials it is possible to have nested
material definitions in Track View. Icons also
appear in an object’s modifier branch w hen a
material is assigned to an object.
Map—Indicates map definitions. All branches
below a map definition are part of that map. This
includes values used by p aramet ric maps and
other map definition that are p art of a map tree.
Object—Indicates objects in the scene.
Branches below the square icon contain linked
descendents of the object. Branches below the
circle icon beside a yellow cube contain transforms
and modifications applied to the object.
Modifier—Indicate modified objects and Space
Warp bindings. Branches below a modifier contain
the modifier’s sub-objects and parameters.
Controller—Indicate animation controllers.
Controllers are the animation workhorses of Track
View. T hey contain the animated v alues for all
parameters and are the only item in the Hierarchy
list that can have a track containing keys. Every
controller has its own individ ual icon. Some
examples:
Position controller
Rotation controller
Scale controller
Cer t ain types of controllers can contain other
controllers. Examples of these are Transform
Cont rollers and List Controllers.

Animation track displayed in track bar below time slider
There are two types of t r acks:
Range tracks indicate when items below the
track are animated. A range bar in the track
displays the range of time over which the
animation occurs.
