Wright Stuff...
If you are using FS9....
Use DXT bmp and "Export" your 'Alpha'.
Take it into whatever program, E.G. PhotoShop or PSP...
And remember...
What ever is lite to dark grey is what makes the reflection. Black is normally used for "Spinners and such".
This is a good link to an in depth discussion...
http://forums.avsim.net/dcboard.php?az=show_topic&forum=200&topic_id=665&mesg_id...If when you look at the 'Alpha' it appears all white...you will have to make your own!
That is a whole different topic...
Now if you are using FSX....you may not be able to get DXT.bmp to convert the "Modified Alpha/Paint Texture" back to .DDS for FSX to read properly.
