2 compositing nodes to add some distance fog in Cycles. I unburried the idea from a tutorial by (the famous) Andrew Price. Give attribution to him, if any. I just made a quick scene to show the effect in action.In the "Map Value" node:-- Offset: Distance of the fog relative to the camera. (Negative values are in front.)-- Size: Acts a bit like a density setting.-- Minimum: Just keep it at zero.-- Maximum: Limits the effect. (Especially useful for the sky.)In the "Add" (Color Mix) node:-- Fac: Map Value. Don't touch. It does all the trick.-- Image (top): Source image.-- Image (bottom): Fog color. You're not limited to shades of grey.Unfortunately, it's not practical to make a node group of this because most of the needed values can't be exposed. Anyway... Enjoy!
