Overview

Shader Behavior Overview

Shader model:

   [2] Standard (PBR)
Supports:

• Multiple tangents

Does not support:

• Punch-through mesh layer
• Transparent mesh layer
• Noise
• Compute instancing

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

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
