Lighting & Rendering • Fog & Atmosphere

 There is a 'fake' fog which is created using the camera and 'real' fog which uses volumetrics.

The 'real' fog is aiAtomsphereVolume.

the original image render and plain fog render.

Now we face aiFog which is the 'fake' version.

The first variant I used here aiAtmosphereVolume seems a little confusing but with enough fiddling can give off a nice looking effect, but also kinda looks a little underwater if you don't reduce it to the right amount.
To use that variant I will need to get a bit more practice in.
