# Get Mesh Triangle Count
|
|
|
|
Menu Path: **Operator > Sampling > Get Mesh Triangle Count**
|
|
|
|
Use the **Get Mesh Triangle Count** Operator to get the number of triangles in a mesh.
|
|
|
|
The Operator assumes the mesh uses default triangle topology, so it outputs the [index count](Operator-MeshIndexCount.md) divided by three.
|
|
|
|
## Operator settings
|
|
|
|
| **Property** | **Type** | **Description** |

The Operator becomes a [Get Mesh Triangle Count](Operator-MeshTriangleCount.md) Operator.</li><li>**Skinned Mesh Renderer**: Input a [Skinned Mesh Renderer](https://docs.unity3d.com/Manual/class-SkinnedMeshRenderer.html) component. The Operator becomes a [Get Skinned Mesh Triangle Count](Operator-SkinnedMeshTriangleCount.md) Operator.</li></ul>|

## Limitations
|
|
|
|
If the mesh isn't [readable](https://docs.unity3d.com/ScriptReference/Mesh-isReadable.html), this Operator returns 0. For information on how to make a mesh readable in the Editor, refer to the [Import Settings for a model file](https://docs.unity3d.com/Manual/FBXImporter-Model.html).
