Its detailed 3d model review animation captured in 3ds Max viewport and same clay renders with simple lighting setup. I spent four days for modeling and couple weeks for animation, clay render & post production. In modeling process I didn't use any tools from "compound object" panel. Everything is modeled poly by poly. Just in final cutaway render I use ProBoolean tool for slicing parts. Summary info: 154 parts; 278.474 polys & 200.033 verts (without TurboSmooth); 4.278.544 polys & 2.142.849 verts (with 2 TurboSmooth subdivisions) Thank You for watching!
