I tried removing static jetways at Sunskyjet KPHL without success.
This scenery contains non-moving static jetways at all terminals. I have confirmed that they are not part of the terminal itself by going into the airport scenery folder. There are two jetway BGL files, and when I temporarily removed them and reloaded the sim, all the jetways were gone. I realize, of course, that this is not a proper solution.
I reenabled the jetways and used the GSX editor to add a SODE jetway at gate D5, which worked fine - the new jetway appeared adjacent to the old one. I then set an exclude radius of 1 meter, saved and exited from the sim.
I used the stand-alone GSX Level 2 config program to compile an exclude bgl, and verified that the file was present in the GSX excludes folder.
However, on re-loading the sim at that gate, the original static jetway is still present adjacent to the new SODE jetway. I repeated the process with increasing exclude radii up to 10 meters, but still cannot get the static jetway to disappear.
The only proviso is that this is an FSX scenery being used in P3DV4, (but installed using the add-on.xml method). In general the scenery works very well in P3D, but perhaps this is preventing the GSX exclude from working?
I did verify, using the Lorby scenery config program, that GSX Excludes has the highest priority in the scenery library, above all other entries.
