Yeah, sure. The dome is just a secondary consideration off the back of the earlier suggestions in this thread to be honest. My main issue is the whole ship just not rendering at 100% scale.

But that's a good point actually... will try a render with a background image and see where that background plane is sitting relative to the ship.

Do you happen to know, is the Poser background image projected onto a plane in 3d space or does Firefly just insert the background image behind all rendered objects?

Will try a render and see what happens...
