## split_mesh(, mesh, policy) {#aspose.threed.entities.Mesh-aspose.threed.entities.SplitMeshPolicy}

Split mesh into sub-meshes by [`VertexElementMaterial`](/3d/python-net/aspose.threed.entities/vertexelementmaterial).
Each sub-mesh will use only one material.
The original mesh will not get changed.


### Returns 


New splitted meshes


```python

@staticmethod
def split_mesh(mesh, policy):
    ...
```


| Parameter | Type | Description |
| :- | :- | :- |
| mesh | [`Mesh`](/3d/python-net/aspose.threed.entities/mesh) |  |
| policy | [`SplitMeshPolicy`](/3d/python-net/aspose.threed.entities/splitmeshpolicy) |  |


## split_mesh(, scene, policy, remove_old_mesh) {#aspose.threed.Scene-aspose.threed.entities.SplitMeshPolicy-bool}

Split mesh into sub-meshes by [`VertexElementMaterial`](/3d/python-net/aspose.threed.entities/vertexelementmaterial).
Each sub-mesh will use only one material.
Perform mesh splitting on all nodes of the scene.



```python

@staticmethod
def split_mesh(scene, policy, remove_old_mesh):
    ...
```


| Parameter | Type | Description |
| :- | :- | :- |
| scene | [`Scene`](/3d/python-net/aspose.threed/scene) |  |
| policy | [`SplitMeshPolicy`](/3d/python-net/aspose.threed.entities/splitmeshpolicy) |  |
| remove_old_mesh | bool |  |


## split_mesh(, node, policy, create_child_nodes, remove_old_mesh) {#aspose.threed.Node-aspose.threed.entities.SplitMeshPolicy-bool-bool}

Split mesh into sub-meshes by [`VertexElementMaterial`](/3d/python-net/aspose.threed.entities/vertexelementmaterial).
Each sub-mesh will use only one material.
Perform mesh splitting on a node



```python

@staticmethod
def split_mesh(node, policy, create_child_nodes, remove_old_mesh):
    ...
```


| Parameter | Type | Description |
| :- | :- | :- |
| node | [`Node`](/3d/python-net/aspose.threed/node) |  |
| policy | [`SplitMeshPolicy`](/3d/python-net/aspose.threed.entities/splitmeshpolicy) |  |
| create_child_nodes | bool | Create child nodes for each sub-mesh. |
| remove_old_mesh | bool | Remove the old mesh after split, if this parameter is false, the old and new meshes will co-exists. |
