Hello,
Ive had this problem for a couple of trys now. Ive exported the DEM and UTM overlays. Yet each and every time Ive generated rails. Or even skipped that part and tried to just manually lay them. There buried underground. Even when I raise the spline heights to ground level, I go to hit smooth spline. They once again go underground. Am I maybe missing a setting somewhere? Or using the wrong kind of DEM data? Ive read the tutorials over and over going over each step and Im kinda stumped. Ive attached a screenshot to show the issue. Thanks in advance for any help given.
