PBR Master Node

Description

A Master Node for physically based rendering. Can be used in either Metallic or Specular workflow modes as defined by the Workflow dropdown parameter.

By default, Shader Graph expects the values you supply to the input Normal to be in tangent space. Use the Transform Node to convert the values to tangent space, or use the Fragment Normal Space drop-down menu in the Material Options to change the expected coordinate space to Object or World.

Ports

Name	Direction	Type	Stage	Binding	Description
Position	Input	Vector 3	Vertex	None	Defines the absolute object space vertex position per vertex.
Albedo	Input	Vector 3	Fragment	None	Defines material's albedo value. Expected range 0 - 1.
Normal	Input	Vector 3	Fragment	Tangent Space Normal	Defines material's normal value. Expects normals in tangent space.
Emission	Input	Vector 3	Fragment	None	Defines material's emission color value. Expects positive values.
Metallic	Input	Vector 1	Fragment	None	Defines material's metallic value where 0 is non-metallic and 1 is metallic. Only available in Metallic Workflow mode.
Specular	Input	Vector 3	Fragment	None	Defines material's specular color value. Expected range 0 - 1. Only available in Specular Workflow mode.
Smoothness	Input	Vector 1	Fragment	None	Defines material's smoothness value. Expected range 0 - 1.
Occlusion	Input	Vector 1	Fragment	None	Defines material's ambient occlusion value. Expected range 0 - 1.
Alpha	Input	Vector 1	Fragment	None	Defines material's alpha value. Used for transparency and/or alpha clip. Expected range 0 - 1.
Alpha Clip Threshold	Input	Vector 1	Fragment	None	Fragments with an alpha below this value will be discarded. Requires a node connection. Expected range 0 - 1.

Material Options

PBR Master Node material options can be accessed by clicking the cog icon in the top right corner of the PBR Master Node.

Name	Type	Options	Description
Workflow	Dropdown	Metallic, Specular	Defines workflow mode for the material.
Surface	Dropdown	Opaque, Transparent	Defines if the material is transparent.
Blend	Dropdown	Alpha, Premultiply, Additive, Multiply	Defines blend mode of a transparent material.
Fragment Normal Space	Dropdown	Tangent, Object, World	Defines the coordinate space of the value supplied to the Normal slot.
Two Sided	Toggle	True, False	If true, both front and back faces of the mesh are rendered.
