Hello @Jkthrp, Thanks! Yes it is possible. That’s what “Apply Landscape Spline” button is for. Select all required roads. Make sure “Raise Terrain” option is checked and set “Deform Width” and “Falloff” parameters to somewhat large values (e.g. 2000, 1500 respectively for smooth hills). Then click “Apply Landscape Spline” button. You may then run “Align To Surface” function to level pavements with the landscape. And then run “Apply Landscape Spline” again with smaller values (e.g. 250, 50) to carve the roads.
Please note, I’ve found a few bugs which may prevent this functions from working properly with such large values. Fixes are going to be included in the next update.
