Shadow Generations Shaders - Common dpnm: Difference between revisions

Revision as of 09:44, 8 August 2025

A standard PBR shader, with an additional color mask texture. The color mask controls the visibility of the diffuse parameter, which gets multiplied with the diffuse texture color. This is useful if you want to animate specific regions of a material.

Behavior

Supports all mesh layers
Uses Shader model 2 (Standard)

Textures


Name	Index	Kind	Red	Green	Blue	Alpha
`diffuse`	0	Albedo	Albedo color			Transparency
`diffuse`	1	Mask	Controls the visibility of the diffuse parameter color	N/A	N/A	N/A
`specular`	0	PRM	Specular factor (multiplied by 0.25)	Smoothness factor	Metallic factor	Ambient Occlusion
`normal`	0	Normal map	Normal map direction		N/A	N/A

Uses the red channel to control the visibility of the diffuse parameter color.

Parameters


Name	X	Y	Z	W
`diffuse`	(RGB) Color multiplied with the sampled diffuse texture color based on `diffuse [1]`			N/A

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.
