Happy and not . I think Eevee render looks okay ,but in Cycles even with denoise(NLM) looks a bit noisy …
Was a bit of a struggle to get this sort of right.
When done the cube for the volume for the fog .only changed density and the anisotropy.
Even tried with another scene as I thought might be bugged or could be the lights …
When density was 1: the fog was dark…not white …basically all the scene invisible to render.World setting is dark,but also changed it to white - same thing happened.
Eventually changed things around to get the results as you see.
Q : why does the higher fog makes all black?
Q: does Cycles need some other settings that were not covered in lessons to make the fog nice looking?
