# PhysicsEditorMeshExtensions

> Extension methods for the Mesh class to configure pre-baked collision data.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor](/engine/6000.7/script-reference/unityeditor.md)
* **Assembly:** UnityEditor

```csharp
public static class PhysicsEditorMeshExtensions
```

## Remarks

This class provides extension methods that allow you to control whether collision data should be pre-baked into mesh assets during player builds. Pre-baking collision data improves runtime performance when meshes are used with [MeshCollider](/engine/6000.7/script-reference/unityengine/meshcollider.md) components.
