I have a problem with NGX shading at night. By day the aircraft is depicted correctly. Also the logo light does not always show in external view when switched on.Nav lights/taxi etc always seem to work ok. ( Dark aircraft in screenshot )I have tried changing airports etc. with no success. Day/Dawn/Dusk views all ok.Help please!

Are you switching between liveries? I've noticed some corruption of night textures if I don't switch to a default aircraft before selecting a different livery.

You can't see it but that's the PMDG livery. I haven't downloaded any others.The aircraft around it are My Traffic X. Is it possible that the PMDG is depicted properlyand the others are too bright. As you've probably guessed I'm pretty new to FSX butI fly commercially so really interested in the amazing simulation achieved in the production of this aircraft.Excellent product!Someone told me on one of the other forums that I might have a night shader problem. Any help appreciated.
