Ah! that explains things.

No, I get it. 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.
