Something like this, I just stopped sampling noise on my volume cube and set it to a base density value and we have volumetric fog and this seems to not be that intensive of a effect at all when not procedurally generating noise ^_^.
I am going to add other light support as well, right now it’s just directional lights but I know how to add spherical lights, and maybe area… but I have lots of other stuff on my plate right now.
Ill post the gitHub repo for the clouds/fog cube here but if you cant wait there is a topic here with a PG and a less refined version Struggling to Convert Global Position to Shadow Map position
