Bob,
Im glad Im not the only one with this issue. I see Harvey above also has the same problem with 3D models since the update.
Did you report it as a 3D software bug and get a new ticket raised with Airnav support ?
Now there is more air traffic, I have carried out further investigation. I notice Im actually missing Easyjet (A319,A320) , Ryanair (B738) , Thomson, Thomas Cook, and British Airways A321, B744 '3d skins', to name a few.
Im also missing many 3D models completely...so I just have a load of empty-headed white marker stalks moving around eg. Aer Lingus (A320), Austrian Airways, Continental, KLM, and BMI.
So 3D is now looking pretty well porked after the update !
