Path Control Menu
TENSION — controls the length of the tension vector. At a setting of 0%,
this imaginary line extends an equal distance into and out of the key-
frame, and the path through the middle keyframe is curved.
CONTINUITY — determines the angle of the path into and out of the key-
frame via the continuity path vector.
BIAS — determines whether the path will be “pulled” towards the pre-
vious or the following keyframe via the bias path vector.
Path Vectors
With respect to a CURVE path between keyframes, each keyframe is made up
of three vector parameters as shown. See the separate Krystal User Manual
for background information and detailed explanations of the Tension, Con-
tinuity, and Bias path controls.
