I had version 2.0 of KLAS, and using the following edits suggested by ORBX with their SCA scenery, it worked great.
DEACTIVATE: (by renaming from .bgl to .bgl.off)
>>> in \Orbx\FTX_NA\FTX_NA_SCA05_SCENERY\scenery
FTX_SCA_objects_KLAS_PLC.bgl.OFF
ADE_FTX_SCA_KLAS_CVX.bgl.OFF
ADE_FTX_SCA_KLAS.bgl.OFF
>>> in \Scenery\World\Scenery
ADE_FTX_SCA_KLAS_elevation_adjustment.BGL.OFF
>>> in \fsdreamteam\KLAS\scenery
mesh_terrain.bgl.OFF
CVX_KLAS.BGL.OFF
ADD: (by extracting and moving the file attached below)
>>> in \fsdreamteam\KLAS\scenery
cvx_FTX-SCA_FSDT-KLAS_compatibility.BGL
I just upgraded to version 2.1 of KLAS, and I cannot find these two files to turn them off.
>>> in \fsdreamteam\KLAS\scenery
mesh_terrain.bgl.OFF
CVX_KLAS.BGL.OFF
Therefore, I am having serious elevation issues with KLAS. Was there a change made to version 2.1, where those two files no longer exist? If so, any chance you could suggest how to fix this?
