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.
