Hi Mike,
Ive run across the same problem occasionally , with 2d panels in a 3d
cockpit. I think the best solution is to add something like this...
--- snip ---
Thanks for the help, Syd! I'll try that out. Makes sense. Well, it wasn't a loss since I learned tons about z-orders in OpenGL, and how FlightGear does it, what z-order fighting is, etc...
I think I figured out the problem was generally caused by the texture not having an alpha channel. But as soon as I added one, all the instruments went away. Can't win on that one... ;)
Anyways, since then, I've restarted from the C172P model and added some rough "pillboxes" on the landing gear. Needs work, but coming along. I dropped in the right engine and prop from the c172r. Starting to look good.
Now, I've got the 3 backup gauges with 3d instruments and a beginning of the PFDs (also 3d) properly placed in the cockpit. Obviously, I'm going through your Primus-1000 implementation, since it's very close to the Garmin G1000. First off, the attitude, altitude and speed displays.
And thanks again for the help, and all the excellent stuff you've done in FlightGear. :)
