Thanks. Do I place the scenery entry above airport scenery entries at the highest layer level?
Doesn't matter, we noticed these excludes are always able to exclude jetways even on higher layers, which is very convenient in this case.
There might be some cases of complex cross-exclusions, depending on which sceneries you have so, if you find them, it might be required to have the FSDT Exclude on the highest layer but, right now, we haven't found them.
