# UnlitMaterial

A material that doesn’t respond to lights in the scene.

## Declaration

```swift
struct UnlitMaterial
```

## Mentioned in

Modifying RealityKit rendering using custom materials

## Overview

Overview UnlitMaterial materials do not respond to virtual or real lighting. Add an UnlitMaterial to a model by setting it as one of the materials in a ModelComponent. let unlitMaterial = UnlitMaterial(color: .red) let model = ModelComponent(     mesh: .generateBox(size: 1),     materials: [unlitMaterial] ) redBoxEntity.components.set(model) For example, a SimpleMaterial on the left, and an UnlitMaterial on the right:  |   |  note: The blending mode of UnlitMaterial materials should be configured explicitly with the blending property for transparent or translucent surfaces.  The opaque mode is used when unset.
