A method for automatically transferring attributes between computer-generated models. The method includes storing in memory first and second models represented by polygonal meshes and storing a set of attributes for the first model. A processor operates or runs a compressed graph generator to process the first and second models to generate first and second compressed graphs that are compressed versions of the models. The method includes comparing topological connectivity of the first and second compressed graphs. When the connectivity is similar, the method includes transferring at least a portion of the attributes from the first model to the second model. The compressed graphs may be motorcycle graphs, skeleton graphs, or other forms of compressed graphs. The method includes determining a pair of vertices in the first compressed graph that match vertices in the second compressed graph for use as starting locations in comparing topological connectivity of the compressed graphs.
