Making a landscape the other day, I started looking for a way to do distance fog to give a better sense of scale.
I started out trying multiple transparent/additive planes, but they definitely made a banded appearance on the ground/on objects.
Then I saw someone mention the heightmap feature and figured that could make something passable. Here’s how I did it: Depth fog in Nomad Sculpt (well, in post) - Album on Imgur
I suspect there’s a good way to use the heightmap for other things, too, like masking a desaturation layer. I’ll keep playing with it and see what I can come up with.
