```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The vertex attribute index (0 to [Mesh.vertexAttributeCount](/engine/6000.7/script-reference/unityengine/mesh/vertexattributecount.md)-1).

### Returns

| Type                                                                                                            | Description                             |

| [VertexAttributeDescriptor](/engine/6000.7/script-reference/unityengine/rendering/vertexattributedescriptor.md) | Information about the vertex attribute. |

### Remarks

This function can be used together with [Mesh.vertexAttributeCount](/engine/6000.7/script-reference/unityengine/mesh/vertexattributecount.md) to query information about vertex attributes that are present in the mesh, without needing any managed allocations.
