What is "Roadbed Layer Overlap"?

It is an advanced feature that allows assigning a different Outer Shoulder material than the main one at the Ends of the ASPHALT S, specifically in the Convert platforms from a drawing of type No text and Slope. For each Layer, you can Configure a Vertical and a specific Slope. This is fundamental to faithfully represent real construction, where asphalt or base layers are often staggered at the edges.
