      | :c:enum:`~A3DStatus` A3DGlobalInsertGraphMaterial(*const* :c:struct:`~A3DGraphMaterialData`\ \* **pData**\ , :c:type:`~A3DUns32`\ \* **puiIndexMaterial**\ )
   
   Creates a new material, returning its index.
   
   
      2.0
   
   
   When given an ``A3DGraphMaterialData``\ , the function searches for an already existing material data of the same value and returns its index. If the material does not exist, it is created and a new index is returned. In case of failure ``*puiIndexMaterial``\ is unchanged.

   **Parameters**
   
   
      **pData**\ : The material data to insert.
   
      **puiIndexMaterial**\ : The resulting index for the input color.
   
   
   **Returns**
   
   
      A3D_SUCCESS or an error code.
