Prop Bone
In 3ds Max, the CSM marker file format supports a prop bone in either or
both hands (left, right, or middle). There are nine additional markers for the
top, bottom, and middle of the three prop types. If the software detects these
tracks, it creates a
dummy helper on page 2615 object.
The length of the prop is the average distance between the top and bottom
prop marker during animation. The prop will be oriented in the plane of the
three prop markers, and its origin will be at the bottom prop marker.
The dummies are named bip01prop, bip02prop, and so on. If a prop of that
name already exists, its animation and size is reset upon loading the CSM file.
The Marker Display dialog contains a check box for toggling display of the
prop markers. The prop track names are LPRPB, LPRPM, LPRPT, MPRPB,
MPRPM, MPRPT, RPRPB, RPRPM, and RPRPT. These stand, respectively, for
left prop bottom, left prop middle, left prop top, middle prop bottom, middle
prop middle, middle prop top, right prop bottom, right prop middle, and
right prop top. You can change the track names by editing the MNM file.
The props don't necessarily have a relation to the left and right hands. For
example, a prop could be a hat.
