Overview
Shader Behavior Overview
Shader model: 
   [2] Standard (PBR)
Does not support:
An advanced PBR shader that uses
- vertex alpha to blend between two albedo textures
- distance blending to apply detail albedo and normal map textures
Warning
  This shader has a severe bug where normals break outside the detail range! 
It is advised to not use this shader.

Behavior
Vertex alpha blending
The shader has two sets of diffuse textures and two sets of PBRFactor parameters.
The shader uses a blend factor to interpolate from the first set of textures to second one.
This blend factor consists of just the vertex alpha.
Distance blending
Uses distance blending to interpolate
| From... | ... to | 
|---|---|
| the normaltexture | the normalandnormal[1]textures blended together | 
| the combined diffusetextures | the combined diffusetextures overlaid with thediffuse[1]texture using detail blending | 
Bugs
Warning
  The shader checks if the surface is within the detail range, and only then applies the detail diffuse and the detail normal textures.
Unfortunately, the surface' normal direction never gets set outside this 
if-block, which means normals are completely broken outside the detail range.Vertex Colors
- Color is not used
- Alpha is used as the basis for the blend factor
