# PhysicallyBasedMaterial.Normal

An object that specifies an entity’s normal map.

## Declaration

```swift
struct Normal
```

## Overview

Overview The normal property of a RealityKit entity holds an optional normal map, which stores fine details about the entity’s surface, using a texture rather than increasing the number of polygons in the model. If you provide a normal map, RealityKit uses the vectors from that normal map when rendering the entity, resulting in greater detail and more accurate highlights, shadows, and reflections.

## Topics

### Creating a normal object
