Hi everyone,

I have a problem with pyro dynamics.

Actually I am trying to simulate smoke coming out from a wall which is got hit and break.

Please correct if i'm wrong, i break the wall use voronoi and i use RBD to simulate the breaking, and then i used that RBD pieces which is already simulated, to generate smoke, so the smoke could trail the flying wall pieces.

The problem is, my chunk size, is a bit small, as it is a wall, its not thick, and its been broken to small pieces which make it even smaller. So the pyro density source (the source purple thingy that emits smoke) becomes jittery and create a lot of small popping in the smoke simulation.

I test something with bigger and thicker box object, it works fine, but when I resize it, then the same problem appears (its the attachment file).
I also tried to increase the voxel grid size (uniform division) into a higher number, it slows down the simulation drastically , but it is a bit better.

I was wondering is there any other way to solve this apart from cranking up the uniform division? Any help will be much appreciated.


Thanks for the time and help guys.
