I had elevation problems, so got some help with my scenry library and now the elevations are good. Now I've got black grass. I've tried the FTX  Central, using the Global, North America and Europe. I went to FTX Europe, FTX Jackson Hole , FS Vancouver, plus default airports in between, all black grass. What could cause black grass ?

Grub worms or Glyphosate?

I just discovered water where land in suppose to be from Chicago to Indianapolis. The skyscrapers were there, but no fish. Also just picture black where grass is suppose to be. In the forest I can see all the trees, but the ground is solid black. I have REX 4, but I don't think that's a problem.

Got it working, accidently had the default texture unchecked in the scenry library.
