2 On the Biped rollout, make sure you are not in Figure mode, then,
click Save File.
3 In the file dialog, choose Step Files (.STP) as the file type to save.
4 Enter a name for the footstep file, and then click OK.
Using Motion-Capture Data
Besides animating a biped with footsteps or with keyframing (freeform
animation), you can import a motion-capture file. The overall workflow for
motion capture is straightforward:
■ Import the motion-capture data
See
Importing Motion-Capture Data on page 4576.
■ Filter the data
Motion-capture files are typically dense, with keys on every frame. Filtering
the data reduces the number of keys, resulting in an animation with better
performance. You filter the data with the
Motion Capture Conversion
Parameters dialog
on page 4592. This dialog can reduce large numbers of
keys at once. It is displayed when you use the Motion Capture rollout to
load a BIP, BVH, or CSM file. Once you have loaded a motion-capture file,
you can filter the data further by clicking Convert From Buffer (also on
the Motion Capture rollout), which also displays this dialog.
See
Filtering Motion-Capture and Marker Data on page 4577.
■ (Optional) Edit the data
Once you are happy with the converted animation, you can use the
freeform animation tools to make specific changes.
TIP The Motion Mixer on page 3699 provides another way to edit motion-capture
data.
Motion-capture files can be one of three file types: the native character studio
BIP format, the BioVision (BVH) format, or the Character Studio Marker (CSM)
format.
For an introduction to using motion capture, see the tutorial “Working with
Motion-Capture Data.”
