This model has 27 objects (5 scene objects, 9 parent objects, and 14 geometry objects). Hierarchy has each arm as a group with correct pivot (so that the glasses arms can be moved individually). The geometry is nice and clean and each has a material assigned.
Unique materials include metal material, lens glass, hdr material, plastic, and black rubber. Includes color, transparency, and reflectance channels.
Texture provided (hdrmap.tif 3000x1500) is used on a sky object for reflections and lighting. REPLACE HDR MAP WITH ANY OTHER TO GET DIFFERENT/UNIQUE REFLECTIONS.
Made natively with Cinema 4D R16 and works perfectly with C4D. Rendered using the default renderer with global illumination, ambient occlusion, and anti-aliasing set to best.
OBJ also provided for raw geometry without materials applied.
