We can set only a solid color in Unity built-in fog. It make scene looks fake. In real environment, things looks warm when you face to the sun and cold when you turn back to the sun because of scattering. And the density of fog is variant in all directions. All these thing are not under the control in Unity built-in fog.
That's why we make this Fog System, named Stylized Fog. In this fog system, we can set fog color with gradient color, control density of fog in all directions, and simulate Atmospheric scattering effect with cheap overhead.
Demo Scene is Included in this asset package.
