# SimpleMaterial

A basic material that responds to lights in the scene.

## Declaration

```swift
struct SimpleMaterial
```

## Overview

Overview SimpleMaterial responds to both real and virtual lighting to enhance realism. Add a SimpleMaterial to a model by setting it as one of the materials in a ModelComponent. let simpleMaterial = SimpleMaterial(     color: .red, isMetallic: false ) let model = ModelComponent(     mesh: .generateBox(size: 1),     materials: [simpleMaterial] ) redBoxEntity.components.set(model) For example, a red SimpleMaterial that is not metallic, and one that is metallic:  |   |
