Thank you so much.
So there is no difference if y]I would put the generated files from my desktop to the data or just click install ?
Also Oscape is for what specifically ?
Well, you'd have to figure out the structure and where they all go, but it's far easier to just click Install and it sets that all up for you. (As it doesn't generate them in the right file structure)
Oscape generates LOD for land and water. You'll still need Object and Tree LOD which can both be done with the CK itself. (Well, sort of. There are some issues with that, but nothing too rediculous)
