This geometry import converter reads SLP ("Render") files which are typically exported by Parametric TechnologiesÆ Pro/Engineer program.
Rather than applying colors to each polygon vertex (as done inside the SLP file), a set of unique colors is computed from the file then these colors are used to create PolyTrans "material" definitions, each using a unique color. Thus, you can easily modify the material assignments of a SLP file by editing or re-assigning new materials once the SLP file has been imported.
