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 (zero), the
curve through the keyframe is gentle as shown in Figure 53.
Note A Tension vector must be present for Bias control to be available.
Figure 53. Bias Control Setting Zero
With the bias set to 1.0, the path is pulled towards the following keyframe.
Entry into and exit from the keyframe is a straight line from the previous
keyframe, and the path of the effect travels completely through KF2 before
turning towards KF3.
