This project is an implementation of the Disney BRDF produced at Walt Disney Animation Studios. DisneyBRDF Paper By Brent Burley
This implementation was done using Unity Engine v2022.3.8.
The repo consists of two files:
- DisneyBRDF_Lit.shader - Consists of the HLSL code for the BRDF itself alongside texture map initializations and a rendering pass for shadow casting
- The code for the BRDF is directly referenced by its GLSL implementation for the BRDF explorer found at the following link:
GLSL Disney BRDF
- The code for the BRDF is directly referenced by its GLSL implementation for the BRDF explorer found at the following link:
- brdf_math.cginc - An include file that is utilized in the first file for all of the essential PBR-related math needed to implement the Disney BRDF.
Note: There are no textures or materials in this repo, just the shader program.

git clone 'https://github.com/dhodzic1/DisneyBRDF_Unity' -
Start a new project in Unity
- In the Project window right click and import shader code via
Import New Asset - Import preferred assets that contain texture maps utilizing the same method as above
- Note that this implementation supports the following texture maps: Base Texture, Roughness, Metallic, Normal, Ambient Occlusion, Reflection
