I'm having a lot of troubles with a cloth simulation for a flag flapping in the wind and I'm starting to suspect that my problems are related to small scale at which I'm running the simulation (length of the flag is 0.04 Blender units).

Is it possible to bake the simulation at a more typical size, then scale down to my mini-flag? Alternatively, are there tricks one can play to work around problems with simulating physics with really small objects?

  • $\begingroup$ imho the bake can't be scaled, but maybe you can describe a bit what "lot of troubles" means, which undesired behaviour you get, so that others could help you better there $\endgroup$ – m.ardito Aug 18 '17 at 20:42
  • $\begingroup$ Out of curiosity, why do you have to work at such a small scale? $\endgroup$ – cegaton Aug 18 '17 at 21:01
  • $\begingroup$ I don't see why it wouldn't work. If for some reason it doesn't, you should be able to parent it to an Empty and scale the Empty (the child object will inherit the scale). I don't have a machine in front of me to test on right now, but why don't you go ahead and try. $\endgroup$ – Mentalist Aug 19 '17 at 2:34
  • $\begingroup$ @Mentalist I tried, and after baking the sim, you can scale (object or edit mode) the original base object but the baked animation will keep same scale as before... the bake keeps its own scale. It needs to be baked again after scaling. $\endgroup$ – m.ardito Aug 19 '17 at 5:51
  • $\begingroup$ @cegaton I have a mix of some really large objects and some really small objects $\endgroup$ – ajwood Aug 21 '17 at 22:54
