I've downloaded and installed the c-47 basepack and united nations textures. The planes show in the menu, but the exterior of the planes doesn't show, just the pilot and what appear to be the windows. If i fly the plane in game it looks the same.
I did not have this problem when i installed the b52.
Good chance that your video card isn't strong enough to render the graphic intensive aircraft.
The easiest way to find out would be to lower some of your slides drastically so you can see if the aircraft shows up even if the rest of the Sim looks terrible for just that experiment.
Lower slides like autogen, clouds shadows, scenery and AI.
Thank you for your reply. I tried lowering the settings, but it didn't work.
Lower or shut off, we are just trying to see if it's your video card.
What are your system specs including the type of video card and power supply wattage.
