CGL Aerials compiled with the latest update will show at a distance while in the Scenery Editor, however once you zoom in, the default textures take over. This is if the project has been compiled, placed into the community folder and the scenery editor has been opened to edit the airport.
Normal behavior: The custom aerial should remain a higher priority than the default terrain.
Actual behavior: Custom aerial despawns as you zoom in.
Edited - Aug. 3
Leaving the compiled package in the generated "Packages" folder will allow the aerials to show in the editor. If these packages are removed from the folder, the aerials will unload from the editor, even if the aerials are located in the community folder.
