Looking at the AFCAD file, it indicates AFCAD D:?FSX/Scenery/APX88410.bgl. I have obtained a parking gates position coordinates map, while showing many gates missing from FSX, though maybe too much work to fix, considering rarely used.
That's the default scenery AFCAD, so GSX will only display gates from the default YBBN airport.
Is there an hierarchy of what bgl files have first use etc..eg, FSX>ORBX that GSX uses, as I notice in FSX there is a scenery editor which offers preferences.
GSX obviously use the same rules as FSX itself: the higher a scenery is on the Scenery Library, the most priority its AFCAD will have compared to one lower on the list. Which means, if your Orbx airport in on an layer higher than default (which is how normally add-ons airports are installed), GSX should use its AFCAD.
However, there are some cases were GSX won't use an AFCAD:
- The AFCAD file is corrupt
- The AFCAD is not self-contained, meaning it doesn't include the minimum needed to define the airport ( parking spots and taxiways ), but relies on the default AFCAD and only improves upon it. In this case, GSX will use the default AFCAD
- There's another file access problem to you scenery folder, or a problem with your scenery.cfg or your paths. You can check this by enabling Logging in the "GSX - Troubleshooting" section, and then post a Couatl.LOG file on startup, that will display information about the sceneries in use.
