You can take the animated biped skeleton and use it to generate a 3ds Max bone structure that follows the same animation, by using the File Export and Import capabilities. In just a few steps, you will be able to take your biped animation and use it without the biped attached.
Biped takes a bow.
Create animated bones from bipeds:
Use the Advanced Bone Options dialog that opens
to set the Bone Objects Width
and Length both to 3.
A bone skeleton appears in the viewport.
The skeleton has the identical animation as the original biped.
See MotionBuilder Interoperability for more information about working with bone animation, FBX files, and the MotionBuilder application.
This tutorial showed you a variety of ways to animate a Biped without using Footsteps mode. In addition, it showed how you can apply a Biped animation to a skeleton made from 3ds Max Bones.
