# Mesh Index Count

|
|
|
|
The Mesh Index Count Operator allows you to retrieve the number of indices in the geometry of a mesh or skinned mesh renderer.
|
|
|
|
## Operator settings
|
|
|
|
| **Property** | **Type** | **Description** |
|
|
| ------------ | -------- | ------------------------------------------------------------ |
|
|
| **Source** | Enum | **(Inspector)** Specifies the kind of geometry to sample from. The options are:<br/>• **Mesh**: Samples from a mesh asset.<br/>• **Skinned Mesh Renderer**: Samples from a [Skinned Mesh Renderer](https://docs.unity3d.com/Manual/class-SkinnedMeshRenderer.html). |
|
|
|
|
### Operator Properties
|
|
|
|
| **Input** | **Type** | **Description** |
|
|
| ------------------------- | --------------------- | ------------------------------------------------------------ |
|
|
| **Mesh** | Mesh | The source mesh asset to sample.<br/>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.<br/>This property only appears if you set **Source** to **Skinned Mesh Renderer** |
|
|
|
|
| **Output** | **Type** | **Description** |
|
|
| ---------- | -------- | ------------------------------------------------------------ |
|
|
| **Count** | UInt | The number of indices in the geometry. If the topology uses a default triangle list, you can divide this value by three to get the number of triangles. |
|

|
#### Limitations
|
|
|
|
The Mesh Index 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)
