Thanks. So, in practice this probably means that I can't have smooth looking objects that I load from file, right? Then this will in turn lead to a need for some sort of (more) efficient generating of shapes. Maybe I should build a small "library" behind the camera and use draw-instance on those; that would probably also suit my needs. Thanks, Kas.
