In Blender, I already baked Rigid Body Physics for about 200 frames. Is it possible to continue baking, or do I need to Free Bake or Free all Bakes and start all over again?

  • $\begingroup$ Very relevant question indeed. But to state the obvious: a simulation is about capturing complex physics interactions. In principle there is no generic way to pick up such a process, other than running the simulation process over again from start. $\endgroup$

What you should be able to do is 'Free Bake' but leave the baked frames in the memory cache (the frames in the timeline should switch to being marked in lighter orange instead of dark orange). Then play your animation (without changing anything about the objects which were previously baked) and Blender should play the 'cached' frames and then continue the animation from the point where the baked frames stopped. Once Blender has completed the simulation up to the new end point then click Current Cache to Bake to convert the cached frames back to a baked animation - without re-simulating.

Note, however, that you have to be very careful not to change anything about the animated objects - otherwise Blender will discard the cache and start afresh when you 'play' the animation, losing your bake. You should ensure that everything about your project (including the baked cache files) is backed up before you try this so as to not risk losing your previous bake if something goes wrong.

    $\begingroup$ @FacebFaceb Yes - it is for Rigid Body - but the same principle should apply for other sim types (Cloth, Soft Body, Hair, etc.) $\endgroup$ Jul 22, 2018 at 10:11
  • $\begingroup$ Of course, it would always be safer to re-bake the whole simulation if that's possible. $\endgroup$ Jul 22, 2018 at 10:12
  • $\begingroup$ After moving some objects, when I am rebaking it doesn't overwrite the data, but continues, how can I start over again? $\endgroup$ Jul 22, 2018 at 10:18
  • $\begingroup$ Free Bake or Free All Bakes should reset the simulation. After freeing, moving back to frame 1 should take you back to the start of the animation and playing from there should simulate afresh. Alternatively, Back following the 'Free' should re-back afresh and should not use the previous simulation at all. If it is then something unusual is happening - perhaps ask that as a separate questions (since this one was regarding specifically continuing from the existing bake). $\endgroup$ Jul 22, 2018 at 10:25
