Overview

Shader Behavior Overview

Shader model:

[2] Standard (PBR)
Supports:

Multiple tangents

Does not support:

An advanced PBR shader that lets you blend between two sets of textures using vertex alpha and a mask texture.

Related shaders

Behavior

This shader has two sets of PBR textures:

diffuse, specular and normal
diffuse[1], specular[1] and normal[1]

The shader uses a blend factor to interpolate from the first set of textures to second one.
This blend factor consists of the vertex alpha multiplied by the transparency textures red channel.

For the specular and normal textures, the blend factor is used as is.
For the diffuse textures, the blend factor is multiplied by the diffuse[1] texture alpha.

Multi-tangent

When enabled, the second set of tangents will be used to unpack the normal[1] texture.

Vertex Colors

Color is multiplied into the blended together diffuse texture color
Alpha is used as the basis for the blend factor

Material Inputs

Textures


Name	Index	UV Index	Kind	Red	Green	Blue	Alpha
`diffuse`	0	0	Albedo	First Albedo color			N/A
`diffuse`	1	2	Albedo	Second Albedo color			Multiplied into the vertex alpha (blend factor), but only for when blending the two diffuse textures!
`specular`	0	0	PRM	First Specular factor; Gets multiplied by 0.25	First Smoothness factor	First Metallic factor	First Ambient Occlusion
`specular`	1	2	PRM	Second Specular factor; Gets multiplied by 0.25	Second Smoothness factor	Second Metallic factor	Second Ambient Occlusion
`normal`	0	0	Normal map	First Normal map direction		N/A	N/A
`normal`	1	2	Normal map	Second Normal map direction		N/A	N/A
`transparency`	0	3	Mask	Multiplied into the vertex alpha (blend factor)	N/A	N/A	N/A

Parameters

This shader does not use any parameters.
