Only problem with the highlevel part approach is you can’t support mirrored
submodels higher up in the rendering tree (like eg the star destroyed mpd
uses) cause it will mess up the normals. Or did you find a way around that?

Change the cull-face orientation ;-)

Duh, I was over thinking it big time. Thinking scaling etc would f-up the
normals, but with mirroring they will stay the same length. So you are right all
I have to do is check if it’s an ‘mirror’ matrix and then change the OpenGL
culling direction for all the subparts.
Thanks.
