Marker Data 969
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 geometr y. These instructions are called
mapping coordinates (page 3–967).
Marker Data
Data f rom a motion-capture device (page 2–1059).
Rather than limb rotational data, m arker data uses
marker positions to specify limb position.
Marker Files
A file from a motion-capture device. character
studio can read two marker file formats:
CSM (ch ara c te r s tu d io marker) (page 3–920)

Markers
In a motion-capture session, m arkers are reflect ive
objects placed on the “actor” or “t a lent. The

record the position of various parts of the talent’s
body while performing motions.
Master Motion Clip Controller
In crowd animation (page 2–1154),acontroller
(similar to the Block controller) that consists of a
list of mot ion clips. When instanced, t hese motion
clips can blend from one animation to another.
The Master Motion Clip controller is accessed via
the Crowd helper (page 2–1187).
Match Frame
For the purposes of combining inverse kinema tic
(IK) (page 3–958) and forward kinematic (FK)
(page 3–944) 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
3–954),thisincludesIKkeysfor:
•Position
•Enabledstate
•Swivelangle
On the IK bones, a match frame includes FK keys
for:
•Rotation

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 determines
which sub-material the surface will u se when you
apply a Multi/Sub -O bject material (page 2–1594)
to the object to which the surface belongs.
Geometric primitives have default material
identification number assignments, just as they
