Hello Umberto,
I tried your suggestion with the mesh patch but KLAS still seems to be sitting on a hill,the plateau is not as steep/sharp as before but there is a definate rise on approach to the airport.
I have MegasceneryX LasVegas, Aerosofts LasVegas scenery and KLAS installed and in the proper order in the scenery lib.Also FSGenesis terrain installed but its on the bottom of all the others.
According to the aerosoft website Sasha has sent a fix to FSDT so I'm not sure if the fix you suggested is the same as what hes talking about.
Still enjoying KLAS immensely but if you have any suggestions how to flatten out the area around KLAS it would be much appreciated.
Thanks
Chris
