This is a high resolution polygon model of a playstation portable with high rez textures applied. Great pains were taken to get this model as accurate as possible. It was modeled in Maya and Mirai then translated and textured in Max and Cinema 4D. The model is not triangulated.
I have been building models professionally for 8 years and I know good geometry. You can be assured that the geometry is well laid out and that there are no bad faces, concave faces, or anything else that would cause this model to shade funky or not work correctly. The groups are well thought out and appropriate for animation.
