I'm using Landscape Splines to place roads, and corner/4way meshes at the end of the spline. Even though my models are precisely compatible, and x and y axis values are all 0 for all the spline control points(same for the corner mesh at the end), the spline road's one side sits a little higher than the other side. This doesn't happen when I use the meshes and snap them together without using the spline. I need the spline to curve the road and give it a natural look, but I couldn't fix this no matter what I did(even flattened the landscape region) what could be the cause for this, and how could I fix this?

So I modeled a pretty basic road model in Blender, just a plane that was extruded, calculated the outside normals over and over again, made sure the face orientation was all correct, marked every sharp edge and properly unwrapped the UV, imported it into UE5.8 with default settings, but everything I tried came out to be good for nothing. What to do?
