Can you post a screenshot?  I'm suspecting that your mapping has gone a bit off .

All you ever wanted to know about posting images but were afraid to ask . . .

What paint program are you using?

It looks like your using the HEIDI graphics driver in Gmax. If so, Change it to OpenGL. What you see basically is inherent to Gmax when HIEDI is used. OpenGL will help but it's still not going to be as good as what you see in your paint program. That said, what you see in Gmax isn't what you can expect in FS either. FS will be better too.

If you use a short cut to launch Gmax, Right click on it and do a properties. Look at the target path and add -h to the end of the path. It should look something like this (%GMAXLOC%Gmax.exe -i gamepacks\FS2004\gmax.ini -p gamepacks\FS2004\plugin.ini -h -q) if you are using the FS2004 gamepack. If you are wondering about the -q, that just tells Gmax to start without the splash screen. The next time you start Gmax you will be prompted to choose a graphics driver. Go for OpenGL. It will be your best choice.

You can also do the same thing through the Customize menu under Preference Settings Viewports tab Display Drivers section. For maximum results go to the Configure Driver under the Display Section and pick 1024 plus check the Match Bitmaps as Close as Possible box under the Appearance Preferences.

Also pick 512 and again check the Match Bitmap as Close as Possible under the Download Texture Size too.

This should give you a notable improvement from what you have now.

Hope this helps
