Having tweaked the sim, I included autogens and found out that in many cases I get trees and houses floating in the air or at sea, etc.I reduced max loading settings, and initial my install went without a problem. So, what is it?

I lowered my mesh resolution to 512 as anything higher causes airports to sit on hills/ridges. 512 flattens the area around airports. This was brought out by scenery experts in a thread I read in the scenery forum. The higher the resolution, the higher things rise.Best regards,Jim

Thanks, it did the job.

My mesh resolution is set at "23" in the cfg file...
