Fog Shader

A shader that makes fog using depth.

How it works.

The fog:

The fog shader changes the alpha of a plane depending on how far away the objects behind it is.

Fog height differences:

By changing the fog intensity in the variables you can change the intensity of the fog. Using a gradient noise texture and subtracting the color value to the intensity the fog appears to have different heights in it.
