Pixelated banding emitter

Post by burnguy » 25 Aug 2018, 14:04

I'm getting a pixelated banding pattern from my emitter object. I thought it had to do with the regular polygon mesh so I broke it up, but still getting the same issue.

I even tried placing a noise texture on the volume with no effect. Any suggestions?

i'd say it's the voxel structure that becomes visible, because your object is slightly rotated, the voxel grid however is not.

I would try to set a bigger "Radius" in the emitter tag. Bigger then the "Voxel size" setting in the conatiner...

I could imagine that it may also help to enable the "Smooth Collision Surface Rendering" in the container. You can find it in the "Simulation" tab, then open the "Solver" -> "Misc" options... there is the chckbox.
I don't know though if it actually helps... i would try the bigger radius first...
