I am new to Unreal 4. I imported a height map from World Machine and built splines to form roads. I used the “Deform Landscape to Splines” tool to level road with landscape. But after deforming I see ugly artifacts or smoothing problems under the road spline. When I try to use the Flatten tool under Sculpt, the flattening applied to whole region, which results in uglier artifacts. I’m posting below:
I cant say for sure as i dont use landscape however typically when I make something like a road I make sure that there is some depth to is so that i can deform the area around the road (simlerish to what you have) to add more character rather then just flat terrain
It is from the scale factor. When I draw splines at landscape scale of 1 and deform the landscape, I get perfect results! When I scale the landscape with high values, the artifacts begin to appear. So if I create a landscape of 1009 and scale if by 4 I will get a landscape of around 4000x4000 cm or 40x40 meters. If I import my cars by scaling down them by 100, will it affect the vehicle physics?
But my vehicle models are around 400x200x200 in centimeters also the mesh viewer says like that. When I import them they will be too large for the landscape. So before importing the models what should be the size of them.
Scale each vehicle to match the real life scale before you import them in engine. Currently it’s saying 4 meters x 2 meters x 2 meters. (If that’s right for that type of vehicle you have there, then the scale is already right and it’s the landscape that’s small instead).

Edit: It also says in the link:
Is 1 vertex per 2 meters more than enough for you? then you should be happy how the landscape deformation to spline is looking bumpy.
