Marker Data 1063
Maps offer the level of realism you look for in
materials. The different types of maps you can use
range from the common bitmap, to the flexible
procedural map.
Formanymaptypes,therendererneeds
instructions telling it where the map should appear
on the geometry. These instructions are called
mapping coordinates (page 3–1061)
.

motion-capture device (page 2–910)
.
Rather than limb rotat ional data, marker data uses
marker positions to specif y limb position.
Marker Files
A file from a motion-capture device. character
studio can read two marker file formats:
•
CSM (character studio marker) (page 3–1014)

•

Markers
In a motion-capture session, markers are reflective
objects placed on the “actor” or “talent.” The

record the position of various parts of the talent’s
body while perfor ming motions.
Master Motion Clip Controller
In
crowd animation (page 2–1006)
,acontroller
(similar to the Block controller) that consists of a
list of motion clips. When instanced, these motion
clips can blend from one animation to another.
The Master Motion Clip controller is accessed via
the
Crowd helper (page 2–1038)
.
Match Frame
For the purposes of combining
inverse kinematic
(IK) (page 3–1052)
and
forward kinematic (FK)
(page 3–1038)
animation, this is a collection of
keyframes that allow a seamless blend between IK
and FK control, or vice versa. On the
IK goal (page
3–1048)
,thisincludesIKkeysfor:
•Position
•Enabledstate
•Swivelangle
On the IK bones, a match frame includes FK keys
for:
•Rotation
• Preferred angles
• Sca le (less frequently)
Material ID
Figure mapped using a multi/sub-object material: material
IDs identify the component sub-materials.
A surface’s material ID is the value that deter mines
which sub-material the surface will use when you
apply a
Multi/Sub-Objec t materia l (page 2–1403)
to the object to which the surface belongs.
Geometric primitives have default material
identification number assignments, just as they
