# OcclusionMaterial

An invisible material that hides objects rendered behind it.

## Declaration

```swift
struct OcclusionMaterial
```

## Overview

Overview Add an OcclusionMaterial to a model by setting it as one of the materials in a ModelComponent. let model = ModelComponent(     mesh: .generateBox(size: 1),     materials: [OcclusionMaterial()] ) smallBoxEntity.components.set(model) For example, on the left is a case of two cubes, the larger red cube is slightly further from the camera and has a simple material. The slightly smaller and closer cube has no material in the left image and an occlusion material on the right image.  |   |
