+/**
+ * @brief Specifies the blob name, assimp uses for exporting.
+ * 
+ * Some formats require auxiliary files to be written, that need to be linked back into 
+ * the original file. For example, OBJ files export materials to a separate MTL file and
+ * use the `mtllib` keyword to reference this file.
+ * 
+ * When exporting blobs using #ExportToBlob, assimp does not know the name of the blob
+ * file and thus outputs `mtllib $blobfile.mtl`, which might not be desired, since the 
+ * MTL file might be called differently. 
+ * 
+ * This property can be used to give the exporter a hint on how to use the magic 
+ * `$blobfile` keyword. If the exporter detects the keyword and is provided with a name
+ * for the blob, it instead uses this name.
