You guys are smart...
Yes, we already thought about this. It will surely work, the issue is, with your approach you will kill all default jetways in FSX...we can probably use a cleaner approach.
Have a look at the attached file, it's a .BGL that contains only 1 dummy object, which is just a triangle 3 meters underground and no textures, so it doesn't impact fps at all.
- Put it into a scenery folder that is always active, like Scenery\Global\Scenery, if nobody is calling the object, it will just stay there.
- When you edit your AFCAD XML, replace the default jetway guid with this one:
9d238734-4f75-4723-bfba-4976ab051fa9
- Compile with BGLCOMP and that's it, your AFCAD is now able to tell GSX were the fake/static/AES jetways are.
