| outIndices | The destination indices array. |
| submesh | The index of the sub-mesh to get the indices for. See subMeshCount. |

Populates an array with the indices for a given sub-mesh from the MeshData.
The destination array must have enough elements to hold the index buffer of the given sub-mesh. See GetSubMesh and SubMeshDescriptor.indexCount. Additional resources: Mesh.GetIndices, subMeshCount, GetSubMesh.
