A simple example showing what can be otain with Vue. You can do the same for landscape of course, if you modify some default Vue textures which are not always great for vegetation. There is only one sun here which produce soft shadows (thus requiring user setting quality, here only 9 subrays per pixel, and best quality) . Of course black parts could be removed by adding a filling light in the right, but this took 40 min for render (933MHz only) so... Will try with no soft shadows, keep tune...
