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

## ApplyAndDisposeWritableMeshData(MeshDataArray, Mesh, MeshUpdateFlags)

Applies data defined in MeshData structs to Mesh objects.

```csharp
public static void ApplyAndDisposeWritableMeshData(Mesh.MeshDataArray data, Mesh mesh, MeshUpdateFlags flags = MeshUpdateFlags.Default)
```

### Parameters

**** (\[MeshDataArray]\(/engine/6000.0/script-reference/unityengine/mesh/meshdataarray)): The mesh data array, see [Mesh.MeshDataArray](/engine/6000.0/script-reference/unityengine/mesh/meshdataarray.md).**** (\[Mesh]\(/engine/6000.0/script-reference/unityengine/mesh)): The destination Mesh. Mesh data array must be of size 1.**** (\[MeshUpdateFlags]\(/engine/6000.0/script-reference/unityengine/rendering/meshupdateflags)): The mesh data update flags, see [MeshUpdateFlags](/engine/6000.0/script-reference/unityengine/rendering/meshupdateflags.md).

### Remarks

ApplyAndDisposeWritableMeshData takes a [Mesh.MeshDataArray](/engine/6000.0/script-reference/unityengine/mesh/meshdataarray.md) containing writeable MeshData structs, and applies the vertex buffer, index buffer, and sub-mesh data to [Mesh](/engine/6000.0/script-reference/unityengine/mesh.md) objects. Use this to create new Meshes using the C# Job System and Burst.

After ApplyAndDisposeWritableMeshData is called, the MeshDataArray struct is disposed and can no longer be used.

## ApplyAndDisposeWritableMeshData(MeshDataArray, Mesh\[], MeshUpdateFlags)

Applies data defined in MeshData structs to Mesh objects.

```csharp
public static void ApplyAndDisposeWritableMeshData(Mesh.MeshDataArray data, Mesh[] meshes, MeshUpdateFlags flags = MeshUpdateFlags.Default)
```

### Parameters

**** (\[MeshDataArray]\(/engine/6000.0/script-reference/unityengine/mesh/meshdataarray)): The mesh data array, see [Mesh.MeshDataArray](/engine/6000.0/script-reference/unityengine/mesh/meshdataarray.md).**** (\[Mesh\[]]\(/engine/6000.0/script-reference/unityengine/mesh)): The destination Meshes. Must match the size of mesh data array.**** (\[MeshUpdateFlags]\(/engine/6000.0/script-reference/unityengine/rendering/meshupdateflags)): The mesh data update flags, see [MeshUpdateFlags](/engine/6000.0/script-reference/unityengine/rendering/meshupdateflags.md).

### Remarks

ApplyAndDisposeWritableMeshData takes a [Mesh.MeshDataArray](/engine/6000.0/script-reference/unityengine/mesh/meshdataarray.md) containing writeable MeshData structs, and applies the vertex buffer, index buffer, and sub-mesh data to [Mesh](/engine/6000.0/script-reference/unityengine/mesh.md) objects. Use this to create new Meshes using the C# Job System and Burst.

After ApplyAndDisposeWritableMeshData is called, the MeshDataArray struct is disposed and can no longer be used.

## ApplyAndDisposeWritableMeshData(MeshDataArray, List\<Mesh>, MeshUpdateFlags)

Applies data defined in MeshData structs to Mesh objects.

```csharp
public static void ApplyAndDisposeWritableMeshData(Mesh.MeshDataArray data, List<Mesh> meshes, MeshUpdateFlags flags = MeshUpdateFlags.Default)
```

### Parameters

**** (\[MeshDataArray]\(/engine/6000.0/script-reference/unityengine/mesh/meshdataarray)): The mesh data array, see [Mesh.MeshDataArray](/engine/6000.0/script-reference/unityengine/mesh/meshdataarray.md).**** (\[List\<Mesh>]\(https\://learn.microsoft.com/dotnet/api/system.collections.generic.list-1)): The destination Meshes. Must match the size of mesh data array.**** (\[MeshUpdateFlags]\(/engine/6000.0/script-reference/unityengine/rendering/meshupdateflags)): The mesh data update flags, see [MeshUpdateFlags](/engine/6000.0/script-reference/unityengine/rendering/meshupdateflags.md).

### Remarks
