# Mesh Vertex Count
**Menu Path : Operator > Sampling > Mesh Vertex Count**
**Menu Path : Operator > Sampling > Skinned Mesh Vertex Count**
The Mesh Vertex Count Operator allows you to retrieve the number of vertices in the geometry of a mesh or skinned mesh renderer.
## Operator settings
| **Property** | **Type** | **Description** |
| ------------ | -------- | ------------------------------------------------------------ |
| **Source** | Enum | **(Inspector)** Choose the kind of source geometry, either a **Mesh** or a **Skinned Mesh Renderer** |
### Operator Properties
| **Input** | **Type** | **Description** |
| ------------------------- | --------------------- | ------------------------------------------------------------ |
| **Mesh** | Mesh | The source mesh asset to sample.
This property only appears if you set **Source** to **Mesh** |
| **Skinned Mesh Renderer** | Skinned Mesh Renderer | The source Skinned Mesh Renderer component to sample. This is a reference to a component within the scene. To assign a Skinned Mesh Renderer to this port, create a Skinned Mesh Renderer property in the [Blackboard](Blackboard.md) and expose it.
This property only appears if you set **Source** to **Skinned Mesh Renderer** |
| **Output** | **Type** | **Description** |
| ---------- | -------- | --------------------------------------- |
| **count** | UInt | The number of vertices in the geometry. |
#### Limitations
The Mesh Vertex Count Operator has the following limitations:
- If a Mesh is not [readable](https://docs.unity3d.com/ScriptReference/Mesh-isReadable.html), this Operator returns uint.MaxValue. For information on how to make a Mesh readable, see [Model import settings](https://docs.unity3d.com/Manual/FBXImporter-Model.html)
