To get just the cockpit textures? No. Not a clue. And yes, it'd be easier if they were zipped. But they aren't. I just downloaded every file listed in "Texture" folder one at a time, put them into a folder named, oddly enough, Texture, and then replaced the folder in whichever plane I wanted them in, entire. The latest version Peter came out with,
airplane_v1.8.0_FA-18C_NH.7z and
textures_v1.8.0_FA-18C_NH.7z, utilized them so doesn't need the main Texture folder replaced with AHMenace's ones, just so you know. I used in them in the 15.2, however, and they made a great improvement. In my opinion.
The only problems I found were that the gear and flap indicator lights, down on the lower left of the main instrument panel, stay on at night when the panel lights are lit. So does the Hook light, right above it's handle, and the Spin Recovery light above that, which should only come on when the Spin Recovery system is activated with it's switch. Not during the day, even with the panel lights on.
If that's the worst problems I can find with them, though, I'll live with them
The crispness and clarity of the cockpit are worth it. My vision isn't the greatest any more, and every little bit helps, so if for nothing else, I heartily thank AHMenace for that.
Sorry I'm not a great deal of help, Dman, but that's the info I have. I have never messed with textures and painting, so I have to rely on others for this stuff. I play with Panel.cfg files, aircraft.cfg and .air files, but never done any textures. I just don't have the patience, I guess. Wish I could offer more.
