I got an email from someone who downloaded one of my FSX sceneries and is using it in P3D. He says there is an elevation problem. I tried to get more information, but he seems to have zero knowledge about such things, and I know nothing about P3D. Is an airport flatten/background created in ADE for FSX going to work in P3D? If not, I'm not going to pursue it any further. Thanks in advance for your help.
