I have set a low resolution smoke simulation using “Pyro Solver (Sparse)”. The desired shape of the smoke is obtained with “Voxel Size = 0.05” (relatively a low resolution).
When I increase or decrease the “Voxel Size” I get something unwanted.
When I increase the“Voxel Size”, the smoke expands more. When I decrease it the smoke contracts.
As you can see in the attached picture, the blocs and rectangles.
So I cached the simulation at that resolution (“Voxel Size = 0.05”), then I increased the resolution of the simulation, following this tutorial.
Sparse Pyro Upres, the easy way. [vimeo.com]
I increased the resolution of the simulation by setting the “Voxel Size = 0.02”.
I thought that after doing an “Upres” for the simulation this would get rid of those artifacts.
Well, the overall resolution of the simulation is increased however I still have some of the artifacts in the final render.
As you can see in the attached screenshot.
So how to get rid of those artifacts and obtain a smooth and clean smoke shape?
Thanks for your help.
