How can I average out a certain range of keyframes? For my Blender rig, I have a bunch of parts that are animated. I want to average out the keyframes so each keyframe is at an equal distance from the other. So for instance I have 15 animated keyframes, I want each animated keyframe to be far from each other by say 5 keyframes.

Is this doable?
Go to dope sheet

Click on the first key frame so that the cusroser is set to that
place

select the keyframes that needs to be evenly space out, can use "B"
to drag select area or any other selection

Press "S" to scale 

and input number "5" if you wish to evenly space out all
keys with interval of 5 frames
