I would like to create an animation in which something blows up, starting at a normal speed, slows down to a stop, and then reforms. I know I can manually spread out the keyframes in the dope sheet editor (by spreading the keyframes farther and farther apart and then pasting a copy in reverse), but is there a way to do this automatically?
Example of distances between keyframes: 1,1,1,1,2,4,8,16,32 || 32,16,8,4,2,1,1,1,1 Where || is where the new keyframes end and I paste a copy in reverse order.
Doing it manually works when the speed change happens over a few frames, but if I want the process to extend over 60-120 frames, the process becomes both harder to correctly guess the distance, and it takes substantially more time. Is there something such as a way to edit keyframe distance in the NLA editor?
Any help is greatly appreciated. Please comment if anything is unclear.
