Embodiments of the present invention include techniques for reducing artifacts in rendered images. In one embodiment, a dual UV engine generates a dual of the graph defined by an initial UV set associated with a 3D model. The dual UV engine then uses existing flattening and layout engines to generate a dual UV set from this dual graph. Using the dual graph to define the dual UV set ensures that the seams corresponding to the initial UV set and the dual UV set minimally intersect.
