I am not sure on this but you might be able to have all the exclude areas in
one bgl. Airport for Windows uses name_EX1.bgl. You could use this
convention. I also think the scenery generator reads all the files in the
appropiate folders (from the scenery.cfg and scenery.dat files) so you could
have separate files, such as, name_EX1.bgl, name_EX2.bgl, etc. The name of the
file is probably not important, just what is compiled inside of it.
I am using BGL Toolkit to make exclude files for FS98 scenery. According to thenotes, it is possible to have several exclude files in the same directory. Whatare the rules for naming them?
