I have a bunch of rigid-body objects that get moved by a force field. I want to reverse the physics simulation so that it plays backwards while other animations, like the camera movement and animated textures, still play back forwards. Is there a way to maybe reverse a Bake of the physics? TIA

  • $\begingroup$ you can "reverse" a force field by multiplying the strength with -1. Is that what you want? $\endgroup$

A solution would be to bake to keyframes then reverse the animation: Select the object(s) then Object > Rigid Body > Bake to Keyframes, then in the Dope Sheet select all the keyframes and press SX-1:

This is a duplicate of a question that I asked and answered a while ago.

How to reverse an animation?

But basically I made an addon that does exactly what you want. Automatically bakes to keyframes, and reverses the animation. It can be found here:
