I have an object with cloth simulation. I play the animation and the simulation is cached (not baked):

enter image description here

Then I change its Subdivision modifier's viewport setting:

enter image description here

And the cache is all gone!

enter image description here

The subdivision modifier is applied after cloth, so there is no reason that it would affect how my physics simulation goes, right? Why does Blender clear the cache? Does it mean I have to bake the cache even for any modifier's change, even they're applied after any physics simulation?

  • $\begingroup$ Ever since 2.80, I felt like the cache refreshing system went loose. In 2.80, it refreshed when it didn’t need to, and later, it seemed like it hasn’t been refreshing when it should. This would be one in the reverse, former case. Just code works in transition, so hold on to your bootstraps $\endgroup$
