The standard PBR shader with no special logic.

Useful for when wanting more variety in the transparency without having it tile the same way as the diffuse texture, as the transparency texture uses the fourth UV channel.

Related shaders

Behavior

Supports all mesh layers
Uses Shader model 2 (Standard)

Textures


Name	UV Index	Kind	Red	Green	Blue	Alpha
`diffuse`	0	Albedo	Albedo color			Transparency
`specular`	0	PRM	Specular factor; Gets multiplied by 0.25	Smoothness factor	Metallic factor	Ambient Occlusion
`normal`	2	Normal map	Normal map direction			N/A
`transparency`	3	Transparency	Transparency; Gets multiplied into `diffuse` alpha	N/A	N/A	N/A

Parameters

This shader does not use any parameters

Vertex Colors

Color is multiplied into the diffuse texture color*
- *Exception: The model is using vertex animation textures
Alpha is multiplied into the diffuse texture alpha.

Technical

Uses the default vertex shader.
