Hello i thought i should create a terrain with lots of roads and more but there is one question how do i add a material to the first generated terrain? Here is a screenshot Ok now i am having bad issue's for example
Go into the terrain materials tab (F3 or button up the top) and you can double click on a material on the right to change it or press the add button to add new ones. The error is trickier but not too hard. You just need to double check your paths and make sure there are no errors inside your .mis. Are you following the quick start guide? http://wiki.beamng.com/Terrains:Quickstart_guide
