# Sample Mesh Index

The Sample Mesh or Skinned Mesh Renderer Index Operator allows you to fetch index buffer data of geometry. Both [UInt16](https://docs.unity3d.com/ScriptReference/ModelImporterIndexFormat.UInt16.html) and [UInt32](https://docs.unity3d.com/ScriptReference/ModelImporterIndexFormat.UInt32.html) format are supported the output of this operator is always an UInt.

## Operator settings
|
|
|
|
| **Property** | **Type** | **Description** |
|
|
| ------------ | -------- | ------------------------------------------------------------ |
|
|
| **Source** | Enum | Choose the kind of geometry to sample, either a **Mesh** or a **Skinned Mesh Renderer** |
|

### Operator properties
|
|
|
|
| **Input** | **Type** | **Description** |
|
|
| ------------------------- | --------------------- | ------------------------------------------------------------ |
|
|
| **Mesh** | Mesh | The source mesh asset to sample.<br/><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/><br/>This property only appears if you set **Source** to **Skinned Mesh Renderer** |
|
|
| **Index** | Uint | The index offset to sample the current index buffer. |
|
|
|
|
| **Output** | **Type** | **Description** |
|
|
| ---------- | -------- | ------------------------------------------------------------ |
|
|
| **Index** | UInt | The sampled index, or zero if input **Index** is out of bounds. |

#### Limitations
|
|
|
|
The Mesh index sampling feature has the following limitations:
|
|
|
|
- If a Mesh is not [readable](https://docs.unity3d.com/ScriptReference/Mesh-isReadable.html), the **Position (Mesh)** Block and **Sample Mesh Index** Operator return zeros values when they attempt to sample it. For information on how to make a Mesh readable, see [Model import settings](https://docs.unity3d.com/Manual/FBXImporter-Model.html)
