Shadow Generations Shaders - BlendDetail_dndnd

Return to shaders list

Overview

Shader Behavior Overview

Shader model:

   [2] Standard (PBR)
Does not support:

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

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 used 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 normal texture	the normal and normal[1] textures blended together
the combined diffuse textures	the combined diffuse textures overlaid with the diffuse[1] texture using detail blending

Vertex Colors

• Color is not used
• Alpha is used as the basis for the blend factor

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.
