Randomize keyframes.jpg


Randomize the values of the selected keyframes in the current action, based on the distance between their maximum and minimum of each channel * the threshold bar.
If all your keyframes have the same value then nothing will happen

Useful for creating variation of animation cycles. for example changing the up and down values of a walk cycle to avoid repetitiveness.

To do: Adding more options for generating randomness, with checkboxes or input values for example:
-Adding random values based on the average of the keyframes instead of only their min and max values.
-Instead of just adding to the values, also options for substruct and multiply
-Switch between only selected to all keyframes
