It took me a while to find the recipe for handsome looking creepy fog results in Unreal Engine with Ultra Dynamic Sky. Here’s how I did it, just so I can reproduce it next time I need it (section in brackets):
- enable Cinematic Quality (A1)
- when using Volumetric Clouds, enable “over opaque” to avoid ghosting issues between fog and clouds (C1)
- enable Volumetric Fog (F3)
- to enhance the effect, increase the volumetric scattering (available for moon and sunlight separately)
- enable Render Global Volumetric Material (optional, but looks cohesive)
