We've published a new teaser for you today,
showing a bit more of the scenery cultivation.
Exciting. Looks really good.
Hope that eventually a user-friendly tool will appear for effectively placing trees and forests in the near future.
Manually, I can take a screenshot of the area from OSM (see illustrations below). Then adjust the image in Photoshop and create a "black and white" photo (black = trees and forests).
High on the wish list is a tool that can "read" the black areas (black = trees and forests) and then "produce" the required files that place trees and forests in Aerofly FS4.
