Cool - many thanks for the self illumination tips. I didn't know how I'd do that!

Also, cool enviro-dome.

I've tried loading that enviro-dome into a scene alongside my spaceship model.

Basically my model ship is coming in at roughly three times as long as the enviro-dome's diameter, when the enviro-dome is scaled up 1000% ...eek!

Keen not compromise on the ship's sheer vast scale... but I think I may have to if I want it to be renderable in Poser. Don't know what else I can adjust in terms of cameras and lighting so I'm starting to think it must be a Poser / Firefly limit I'm hitting?
