# inflateMesh

> Allow the physics engine to increase the volume of the input mesh in attempt to generate a valid convex mesh.

## Definition

* **Type:** Property
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.PhysicsModule

> **Warning:**
>
> **Deprecated.** MeshCollider.inflateMesh is no longer supported. The new cooking algorithm doesn't need inflation to be used.

```csharp
public bool inflateMesh { get; set; }
```

### Remarks

The physics engine imposes restrictions on the number of vertices and faces of convex meshes used for collisions. For that reason, the minimum-volume convex mesh automatically generated from the original non-convex mesh may not be suitable for use in physics. In order to address that, the mesh inflation can be used. It effectively extends the source data by a margin of [MeshCollider.skinWidth](/engine/6000.0/script-reference/unityengine/meshcollider/skinwidth.md) and bevels the sharp edges so that the resulting mesh suits physics better.

**Note**: Setting this to true can decrease the accuracy of the collision mesh. Inflating a MeshCollider creates a new instance of the input mesh. This takes additional memory.
