Corridor
Here’s my attempt at recreating one of the corridors from Silent Hill: Townfall.

This required playing around with volumetric fog. I never quite got the fog to do what I wanted but I learnt about a few different volumetric nodes and how they work.
To get the fog where I wanted I used a mix of two gradient textures to try and get the fog most dense lower to the floor, but I struggled to do this without not getting enough fog in the higher areas.
It took me awhile to work out that I needed to add a Volumetric Absorbtion node to get the further away light to dim. It ought to be possible to do with the Principled Volume alone but I couldn’t seem to figure that out no matter how much I tried.
I believe I could also try and do the same scene with simulated fog, so I might try again in future and see how this goes.
