Cloth Simulator: "Free all bakes" doesn't clear bake, but "Free Bake" works
Closed, ResolvedPublic


System Information

Blender Version

Short description of error
In a cloth sim with just 2 meshes with 1 quad each, when I delete one mesh and press "Free All Bakes" and then "Bake All Dynamics" in the Cloth Cache panel, the effect of deleting the mesh is not taken into account. When I press "Free Bake" and "Bake", it works.

Exact steps for others to reproduce the error

  • Load File
  • Delete the larger vertical plane
  • Select the smaller horizontal plane
  • Press "Free All Bakes" and then "Bake All Dynamics" in the Cloth Cache panel => The quad moves around strangely
  • Press "Free Bake" and then "Bake" in the Cloth Cache panel => The quad doesn't move as expected.

Best regards,

Please test latest 2.75 release from and latest nightly builds from to see if the issue still exists in there. 2.74 is quite old now..

Dear Sergey,

I tested with 2.75. The effect is the same. Do you think it is required to test the nightly builds? 2.75 is just a few days old. Or was there a lot of activity in this area lately?

Best regards,

Can confirm the issue.


I posted some debugging to bf-committers
Briefly, the problem is a difference between 'Bake' that clears the cache and 'Bake All' that does not because of cache flag conditions.

Hope this helps
