Here's a first impression of that better 'Bubble Ship' model I told you about:

It didn't spend much time yet in LuxRender, but you can see it is seriously better than the first model. This one is also a freebee from GrabCAD, but unfortunately I am not allowed to give you a link to it here on Rendo.

Still can't see what causes those black bits though, the logic behind it escapes me at the moment.

Cheers!
