read my text correctly !!
I don't know what you are trying to say here ( I've edited your post, because you quoted the whole message wrong, making it unreadable ) but, it's clear the only one not reading text correctly, is you.
I don't know in how many other different ways I can explain that:
- BOTH GSX vehicles and default ground vehicles will use vehicle paths, if the scenery has them.
- BOTH GSX vehicles and default ground vehicles will use taxiways, if the scenery doesn't have vehicle paths.
- Some 3rd party airports can come with custom ground traffic that doesn't use the AFCAD vehicle paths, but has its own internal database of paths, so they can follow the correct lines even if they are not in the AFCAD.
This has been proven in all cases:
1) At a default airport (your video from default KORD), which show a default ground vehicle using vehicle paths, thanks to the fact the default AFCAD from KORD DOES have vehicle paths.
2) At a 3rd party airport (my screenshots from EDDP), which show a custom ground vehicle using the vehicle paths, even if the AFCAD doesn't have them, because it uses a different animation method that doesn't rely on the AFCAD
3) At a 3rd party airport (my screenshots from EDDP), which show a default ground vehicle using the taxiways, BECAUSE the AFCAD doesn't have vehicle paths.
Really, I don't know how I could explain it any better than this, and it's clear GSX vehicles behave just like default ground traffic, in the way they BOTH need vehicle paths in the AFCAD, otherwise they will use taxiways. Normal, obvious, and reasonable.
