3D on LetMeJizz
Nothing on screen was ever filmed, every body built pixel by pixel and posed by an animator. That freedom is the whole appeal, proportions and scenarios no real shoot could pull off rendered in sharp detail. The look ranges from glossy game-engine realism to deliberately cartoonish, but none of it pretends to be live.
