The lighting models are used to describe how the surface of an object affects and interacts with light.
The currently supported lighting models are as follows.
|Light Model Name||Description|
|standard||PBR lighting, supporting GGX BRDF distribution of isotropic and anisotropic lighting, supporting convoluted ambient lighting.|
|toon||Simple cartoon lighting, step-like lighting effect.|
The built-in shader functions related to the lighting models are placed in the internal/chunks/lighting-models/includes/ folder, During the Surface Shader Assembly phase, using
include to import the corresponding code, the lighting calculation can be completed.
