You will need the Fighters Anthology Toolkit installed. Check my tutorial here:
http://farc.3synergy.net/tutorials/shapes.phpFor step 2, here is my recommended revised procedure:
Open up the Fighters Anthology Toolkit. Go to the Missions ---> Mission File screen from the menu. This is to create the initial cache.m file (this assumes it has not been created already).
Download the custom cache.m file located in a zip file here:
http://farc.3synergy.net/misc/cache.zipThen, use Windows Explorer to browse to the "Fighters Anthology/Toolkit/Cache" directory, and replace the existing with the one you downloaded.
Proceed to step 3.
If you don't mind that your new dark grey 747 will replace the existing 747 color scheme, you can omit steps 4 through 6, and proceed to step 7. Steps 4 through 6 are to make the shape/texture combination unique and not replace the original shape/textures, so you could assign a dark gray 747 scheme to an aircraft, while retaining the light gray 747 in the game. These steps require using a hex editor.
Let me know if you have any questions.
