Declaration

var lightingModel: CustomMaterial.LightingModel { get }

A custom material’s lighting model determines exactly how RealityKit uses the values set in your surface shader’s to render the entity.

Custom materials supports the following lighting models:

Lighting Model	Description	Supported Shader Outputs
`.lit`	Uses physically based rendering techniques, but excludes clearcoat.	All except `set_clearcoat()` and `set_clearcoat_roughness()`
`.clearcoat`	Uses physically based rendering techniques, including clearcoat.	All
`.unlit`	Renders without any shading or lighting calculations. The result is similar to using an Unlitmaterial.	Uses `set_emissive_color()` only
