This cartoon glasses model was modeled/optimized for Subdivisional surfaces. The native file format is Cinema 4D. The Cinema 4D file is setup with symmetry so you can edit the width of the glasses easier. You only have to alter one side. It's also setup with SDS on a low res cage model, materials, a light and an HDRI sky object. You just need to load an HDRI image to the empty HDRI material balls luminance channel.

The FBX and OBJ's come in a cage resolution, and in high resolution formats. The obj does not have materials. The FBX does but will need tweaking to match the look of the preview images that were generated from the Cinema 4D file.
