Unity-Stochastic-Shadergraph

Shadergraph package for stochastic texture manipulation for Unity HDRP

• Original Design works

Important

This shadergraph was created using Unity 6 HDRP, thus a caveat is I am unsure of it's compatibility with previous versions of Unity/Shadergraph and other non-HDRP pipelines.

Warning

It is always a good idea to either back up your current project or create a completely separate project with your main project's settings before implementing packages!

Modernized Functionality

This shader offers standard functionality of the HDRP/Lit shader such as

• Diffuse, Normal & Mask map texture output.
• Tiling and Offsets
• Remapping of Normal strength, Smoothness & Metallic channels of the mask map.

Note

A default value of 0.1 Metallic and 0.1 Smoothness will provide similar results as the HDRP/Lit default shader values.

Example Use

Diffuse, Normal and Mask map textures across two adjacent planes, where the left is the default HDRP/Lit Shader material and the right is the Stochastic Shader.

Caution

As outlined in the original Reddit post linked above, this shader's approach is not ideal for textures reliant on pronounced patterns and defined details. See the below example.
