Smoke banding in render We're a small studio using Blender for VFX work.  I have a large simulation of a building on fire and noticed that the smoke is banding in the upper left corner as seen in the attached picture.  The bake alone took 3 days, so I would like to avoid re-baking if possible.  Does anyone know if there is a render setting that might fix this?
You can try the Cubic volume interpolation method and Distance sampling. Settings supported on CPU only:


Distance sampling: Best for dense volumes with lights far away.
Cubic: Smoothed high quality interpolation, but slower.

Linear vs Cubic:

GPU support for Cubic interpolation is added in 2.8 version:

Commit 2d92988f6bc4 &amp; f61c340bc15e: CUDA and OpenCL rendering support for cubic interpolation with images and volumes.
