Good afternoon i read your documentation and i have a question.
When you are talking about the r.VolumetricFog.GridSizeZ (you have a gif to show the difference) you put the next sentence “Lower values give higher resolution on the Volumetric Casting but are also more expensive:”
Inside the documentation about the same topyc, volumetric fog in the unreal engine documentation it said the opposite “The number of Z slices can be adjusted by using r.VolumetricFog.GridSizeZ, where higher is better quality, but will be more expensive.”
I have a question about that because the information seems different in both documents. May you give me please more information about this topyc, I am interest about it.
