Self Diffuse

An object can emit light by itself. You can enable this behavior by attaching something to the selfDiffuse input node.

SelfDiffuse mode

This produces the following equation [2]:

result = selfDiffuse

Note: For this shader, the shadows are applied only if realisticShadows is Off.

SelfDiffuse plus real-time lights

You can also add real-time lights to the self diffuse object by connecting the diffuse and/or specularColor input nodes.

The equation [1] becomes equation [1.b]:

result = selfDiffuse + (probesAmbient*diffuse) + (lights*diffuse) + (lights.specular*specularColor) + (sun*diffuse*sunShadows)

Examples

Equation [1] becomes Equation [1.b].

Equation [2]

In the last image, the self diffuse is so much that there is no need to calculate the other lights. Their influence would be insignificant.
