What exactly is the problem????

You need to explain youself

thats easy, you need to create an alpha channel

paint the windows a solid color (1 technique) and go to alpha on DXTBMP and select that color as the new alpha channel, it should work

If you are going from FS.9 to FS.X tha alpha value has changed..it's almost opposite depending on the material settings

The alpha is probably there you could try inversing it to start with.

The wording under the rear cockpit looks back to front one side

I've never done any texture work at all. Most of this stuff is foreign to me (much better with the tech side of things). Looking to eventually do a repaint and wanted to start small. Thank you all for your replies!
