You need the following for an airfield to show up in CFS3
- a (collection of) .dds file(s) with the airfield's texture(s).
- two .mos files, one for spring/summer and one for autumn/winter.
- a facility file that gives the coordinates of all models on the airfield, the size of the airfield plane, a reference to a runway file, routes for driving vehicles etc.
- a runway file that defines it's dimensions and the take-off positions.
- an entry in both global_layer files.
- an entry in the QC file.
- an entry in the cutscenes file
Some time ago I made a flowchart (actually two - scroll down in the attached .pdf) showing the general plan of CFS3 facilities. It also applies to airfields. It serves as an overview of the programs and steps involved to produce one. Maybe it is of some help:
PS. Perhaps you already know this but might I suggest you make your amendments in a layered Photoshop .psp file and not to the .bmp directly?
Repeated opening and saving / converting the file seems to degrade it's quality. It's best not to re-open the .dds in DXTBmp and send it to your paint program for editing. So save your layered .psp as .bmp, convert to .dds and check in CFS3. If you need to change things, make these changes in the layered .psp file, save as bmp and convert to .dds and check again in CFS3. Repeat these steps until you are satisfied with what you see in CFS3 (and now you know why things may take such a long time ;-)
