    B-5 Keyframe Path Control Path Vectors With respect to the path between keyframes, each keyframe is made up of three vector parameters as shown below. The soft knob controls act on these vector parameters to adjust the path into (entry) and out of (exit) the keyframe. The path through KF2 is parallel with an imaginary line drawn between KF1 and KF2 ...

    B-6 Appendix B — Keyframe Facts Tension Control In the example below, the keyframes are at right angles so the TENSION control operates on a 45° line drawn through the keyframe.

    B-7 Keyframe Path Control In Example 2, the TENSION control is increased to 1.00, so that the Tension vector is shortened to non-existence through KF2.

Example 2 Tension = ...
