[quote name='Nhawks17']Yeah if you go into the Stock Visual Enhancements/EVE folder you can delete the Terrain folder.[/QUOTE]
Thanks for your answer!
My bad, I should have been more specific: Deleting the Terrain folder does work, but it also disable city lights, I was trying to find a way to keep them enabled and *only* disable the new terrain. I tried toying with the terrain.cgf configs, but the weird grass thing remain regardless. At best, you can change the display distance so that it only shows when the camera is very close (I could get behind that). Unfortunately, since the vanilla terrain shader is suppressed, this doesn't solve anything as you have a very ugly and basic Kerbin terrain below. (By the way, you have a grass.dds file in Terrain/Textures that does nothing :D. The first thing I tried was change it's content in visual studio, but it doesn't affect anything.)
I know this is a very specific request (disable the new kerbal terrain, but not city lights), but I'd really like to keep your city lights on, they are really cool!
Even if there is no solution for this, thank you for your time either way :)
