Keyframe Path Control
Bias Control
The
BIAS
control determines whether the path will be “pulled”
towards the previous or the following keyframe. With extreme
settings, all of the biasing will occur either before or after KF2.
With bias set to 0, the curve through the keyframe is gentle as
shown in Example 7 below.

NOTE:
A Tension vector MUST be present for Bias control to have an
effect.
