THE PROBLEM

There is no way to randomize keyframes Maya.

THE SOLUTION

Randomize Keyframes is a simple UI that allows you to randomize keyframes and set the random scale interactively.

Either select the Channel Box attributes you’d like to randomize, or the animation curves and run.

USING THE TOOL

Select keyframes in the Graph Editor or use the Channel Box selection and run.
– Graph Selection: Priority. Uses the selected keyframe’s frame range.
– Channel Box Selection: Secondary. Uses the timeline settings.

Tweak the random scale after running. Click Done to finalize or to use another selection.
