# Animation: customize bounce interpolation

I want to animate a plane falling onto the ground.

It’s good to have the bounce interpolation however you are quite limited when you want to customize it, for example adding more smaller bounces to the end etc, just like you are able to in After Effects.

Is there an addon available to adjust that or is there even a solution within Blender which I just haven’t found?

There is no way to customize them.

The only way out is to not use the premade interpolations. Stay in Bezier interpolation, and use "free" handles to create your own bounces:

No, you can't adjust the bounce interpolation.

However, there are manual ways to progress from your state.

Select the two encasing keyframes and press ShiftO (2.7x) or ShiftAltO (2.8x) to sample frames between them, reset their interpolation type to Bezier afterwards. You can now manipulate them as you wish. Note, that this is also important as the down position will often not fall on full frames.

You can also ghost the curve by pressing the ghost icon and use it as a reference.

• For Blender 2.8 it's Shift Alt O to sample keyframes or Key > Sample Keyframes in the dope sheet menu. Jun 2, 2021 at 18:07

Question for you guys, how do you do a REVERSE bounce, so that it is essentially a mirror of the first bounce? This is what I get when I apply a bounce to my scale.

• Ask yourself what you don't like about your reverse bounce. Think about what the curve would look like that fixes that. Make it so. It's really an artistic decision and goes to what effect you're trying to achieve. Aug 20, 2021 at 0:23
