No Fly pathing?

[M0RT]

Is there a way to create fly-unpathable areas? Only thing I found were no-fly zone, that cover basically no area, are round, and are not really a pathing zone (units will try to move through them and get stuck - it's like if created a trigger that kick unit out of forbidden zone - it looks horrible)

Only thing I could think of was using cliff areas as fly-accesible and using some cliff walker mover for flyers, instead of fly movers. But for that, I would need to create custom footprints for everything, since I can't add cliff pathing in pathing editor.
That brings me to point two - is the footprint editor really still broken?

EDIT: Ok NoFlyZones can be resized, but they still don't act like proper pathing blockers, the all the flying units look like they are trying to crash into every single building.

I think you can press I or T. Don't remember which one it is, to be honest, but you can do it. It's like a pathing editor.

Really? I noticed there is an display option for "no fly pating", but I found no editor (it's neither I or T)
Thanks anyway
