 The function input allows you to change how the shading is computed, there is also an option to compute the illuminance,​ which is just the amount of light hitting a spot regardless of the surface normal. The function input allows you to change how the shading is computed, there is also an option to compute the illuminance,​ which is just the amount of light hitting a spot regardless of the surface normal.
 +===== Controls =====
 +==== Light ====
 +This allows you to select a single light to use for shading. If set to (none), all lights will be evaluated.
 +==== Shading Model ====
 +There'​s three shading models available, however, Raw Light and Half Lambert are mostly experimental.
 +  * **Lambert** performs standard Lambert shading
 +  * **Raw Light** Just returns the light values without performing any shading
 +  * **Half Lambert** is a hacked lambert shading initially developed by Valve https://​developer.valvesoftware.com/​wiki/​Half_Lambert
 +
 +==== Receive Shadows ====
 +
 +If this is turned on, the node will compute received shadows. Otherwise they will be ignored.

 +===== Inputs =====

 +The **Function** input allows you to attach a function to tweak the shading.
