1. A texture mapping system, comprising: memory for storing a first texture map and a parametric texture map; and a texture map manager configured to combine at least a portion of the first texture map and at least a portion of the parametric texture map, the texture map manager configured to determine a texture map type for the first texture map and a texture map type for the parametric texture map and to perform a prioritization of the texture map portions based on the determined texture map types, the texture map manager further configured to select, for conversion, one of the texture map portions based on the prioritization and to convert the selected texture map portion into a form corresponding to a form of the non-selected texture map portion.
