I always thought that I had to install the Terrain Mesh- and /or Landclass scenery at a lower level (I mean with a lower area number in the scenery.cfg file) than the airport scenery in the area covered by the Terrain Mesh- and /or Landclass scenery.
In the last Landclass scenery I downloaded (kphxarpt), in the readme file is mentioned “Make sure that you list KPHX airport scenery before the PHXMESH scenery”.
So my question is : Must I install the Terrain Mesh- and /or Landclass scenery before (lower area number in scenery.cfg file) the corresponding Airport scenery or must I install the Terrain Mesh- and /or Landclass scenery after (higher area number in scenery.cfg file) the corresponding Airport scenery.
