Here is my rendered output of a small sample to demonstrate the issue I'm having: https://gfycat.com/obedientkindlyguernseycow
When I look at any of this in Blender's rendered view, I don't see the blocky artifacts in the smoke that you see here. So I'm not sure how to fix this in my renders. Has anyone encountered this before? Viewport render is at 256 and the Render setting is 1024.
The domain was baked with 1024 Resolution Divisions with 12 max timesteps and 15 samplng substeps for the emitters.
I've also noticed that the effect is more pronounced in the animation output vs in my still renders. But I thought that each uses the same settings?
