Indirect Specular Light Node

Indirect Specular Light retrieves the specular reflections from Unity's global illumination system. This is equivalent to say it retrieves the reflections from reflection probes. It's only useful when doing some sort of custom lighting, thus the node is only visible in the available nodes menu if the Light Model is set to Custom Lighting and displays a warning if it ever happens to be outside of it. NOTE: This node should be only used over connections made with the Custom Lighting input port from the surface Output node.

Nodes used: Texture Sample, Float, Indirect Specular Light

Node Parameter	Description	Default Value
Normal Space	Lets you select the space the Normal input port needs to be in Tangent: Changes the Normal input port to accept values in tangent space. (internally does a tangent to world conversion) World: Changes the Normal input port to accept values in world space and changes it's name accordingly. This is useful in case other nodes are being used that also require world normals by preventing multiple unnecessary tangent to world conversions.	Tangent
Smoothness	A constant value that blurs the resulting reflection. Smoothness is the inverse of Roughness(S = 1 - R). A value of 1 means a perfect mirror reflection while a value of 0 means a perfect matte material. Only visible if respective port is not connected.	0.5
Occlusion	A constant value that darkens the resulting reflection. Only visible if respective port is not connected.	1

Input Port	Description	Type
Normal	The normal value to change the the retrieval of the indirect diffuse light. If left unconnected uses the mesh default normal.	Float3
Smoothness	A value that blurs the resulting reflection. Smoothness is the inverse of Roughness(S = 1 - R). A value of 1 means a perfect mirror reflection while a value of 0 means a perfect matte material.	Float
Occlusion	A value that darkens the resulting reflection.	Float
