On the Track Selection rollout, click Lock COM Keying to turn
it on, then turn on all three tracks (Body Horizontal, Body Vertical, and

IMPORTANT This step is essential if you want to animate the rotation. If the
COM is not locked, and all three tracks are not turned on, then when you
click Set Key, 3ds Max sets keys only on those tracks that are selected. The
resulting animation can be strange and unexpected.

this operation.

axes while Body Rotation focuses on its rotate axes. Once you turn them on,
you can move or rotate the COM by either using the Transform gizmo, by
entering values in the
