■ If you specify Load Buffer Only in the Motion Capture Conversion

Parameters dialog

on page 4592, the motion file is loaded into the

motion-capture buffer without altering the biped animation. Use this to

paste posture and limb keys from any file onto the biped animation in

your scene.

When you load a motion-capture file, the motion-capture buffer is loaded

with motion-capture data from that file. This buffer is altered during

calibration. It is also used to show the motion-capture markers and trajectories.

Internally, there is only one motion-capture buffer. It is often large, so its

contents are not saved before a file load or a calibration. Therefore, if you

undo a motion-capture file load, the contents of the motion-capture buffer

do not change. That's why you'll still see old markers and trajectories. It is not

possible to undo calibration.

Marker Files

Unlike a BIP or BVH file that contains limb rotation data, a

CSM marker file

on page 8037 contains only marker position data. When a raw marker file is

imported, only marker position data is buffered in the motion-capture buffer.

3ds Max uses the marker data to extract limb rotation data to position the

biped. After using the calibration controls on the Motion Capture rollout to

correct biped scale and posture relative to the markers, use

Convert From

Buffer

on page 4589 to filter the raw marker data to key reduce and extract

footsteps.

NOTE A CSM marker file is an ASCII file.
