The place to talk about X-Particles and Cycles 4D


All of my smoke attempts have turned out very blocky

Recommended Posts

Are there other things I should adjust other than Voxel size? 


Or is smoke resolution solely determined by voxel size?


For reference I am Caching out my ExplosiaFX to VDB so I can render via Redshift.

Any relevant links or tutorials are very much welcomed. I have googled and check all of the manuals, and I can only find "noise in smoke renders" but not "blocky smoke"

Can we see the output. I'm hoping that redshift adds the channel data straight in a rs volume at some stage. That way you have flexibility to go interactive till the final render and use rs proxies at where needed.

Voxal size will affect blockyness and also what your explosiafx source is, also if its set to surface to or volume in the source tag.
