# BlendShapeBufferLayout

> Determines the data that Unity returns when you call Mesh.GetBlendShapeBuffer.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.Rendering](/engine/6000.6/script-reference/unityengine/rendering.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public enum BlendShapeBufferLayout
```

## Remarks

When you call `Mesh.GetBlendShapeBuffer`, you can access one of two buffers containing blend shape vertices. Use this value to determine which buffer to access. The default is [BlendShapeBufferLayout.PerShape](/engine/6000.6/script-reference/unityengine/rendering/blendshapebufferlayout/pershape.md).
