ShaderLab syntax: Fog

Fixed function fog parameters are controlled with Fog command.

Fog commands might have no effect when fragment programs are used; as in that case fog operations sometimes are described in the shader.

Fogging blends the color of the generated pixels down towards a constant color based on distance from camera. Fogging does not modify a blended pixel's alpha value, only its RGB components.

Syntax

Fog { Fog Commands }

Specify fog commands inside curly braces.

Mode Off | Linear | Exp | Exp2

Defines fog mode. Default is exponential squared fog (Exp2).

Color ColorValue

Sets fog color.

Density FloatValue

Sets density for exponential fog.

Range FloatValue , FloatValue

Sets near & far range for linear fog.

Details

Default fog settings are based on Render Settings: fog mode is either Exp2 or Off; density & color taken from settings as well.
