Nothing says pumpkin pie and gobs of candy like a good ol’ rendering contest. SolidBox’s Technical & Marketing Director couldn’t resist KeyShot’s Halloween Rendering Contest, so here goes nothing. Does this rendering of a circa-1920 Mercer 4-cylinder engine block & manifold resemble anything close to a pumpkin? No? I’d watch out if I were you. You don’t want people smashing these puppies on your front doorstep.
