```luau
MeshPart.DoubleSided: boolean = false
```

### MeshContent

```luau
MeshPart.MeshContent: Content
```

- Tags: Write: Not accessible, Read capabilities: Basic

The mesh that is displayed on the [`MeshPart`](https://rapi.sleaze.dev/classes/MeshPart.md). Supports [asset URIs](https://create.roblox.com/docs/projects/assets#asset-uris) and [`EditableMesh`](https://rapi.sleaze.dev/classes/EditableMesh.md) objects.

**Deprecated:** This property is deprecated and should not be used in new work.

Deprecated legacy flag associated with the part's [`JointOffset`](https://rapi.sleaze.dev/classes/MeshPart.md).

### MeshID

```luau
MeshPart.MeshID: string = ""
```

- Tags: Deprecated, Hidden, Not replicated, Not scriptable, Read capabilities: Basic, Load only

### JointOffset

```luau
MeshPart.JointOffset: Vector3 = Vector3.zero
```

- Tags: Deprecated, Hidden, Write: Not accessible, Read capabilities: Basic

## Methods

### ApplyMesh

```luau
MeshPart:ApplyMesh(meshPart: Instance)
```

- Tags: Capabilities: Basic

Overwrites the [`MeshContent`](https://rapi.sleaze.dev/classes/MeshPart.md), [`TextureContent`](https://rapi.sleaze.dev/classes/MeshPart.md), and collision geometry properties of this [`MeshPart`](https://rapi.sleaze.dev/classes/MeshPart.md) from the given source `meshPart`.

Parameters:

- `meshPart`: The source [`MeshPart`](https://rapi.sleaze.dev/classes/MeshPart.md) whose [`MeshContent`](https://rapi.sleaze.dev/classes/MeshPart.md), [`TextureContent`](https://rapi.sleaze.dev/classes/MeshPart.md), and collision geometry (along with [`RenderFidelity`](https://rapi.sleaze.dev/classes/MeshPart.md), [`CollisionFidelity`](https://rapi.sleaze.dev/classes/TriangleMeshPart.md), [`FluidFidelity`](https://rapi.sleaze.dev/classes/TriangleMeshPart.md), and [`MeshSize`](https://rapi.sleaze.dev/classes/TriangleMeshPart.md)) are copied onto this part. The object must be a [`MeshPart`](https://rapi.sleaze.dev/classes/MeshPart.md), otherwise the call throws an error.

### GetSurfaceSlotsAsync

```luau
MeshPart:GetSurfaceSlotsAsync(): { any }
```
