When building a gradually sloping road using slabs, the front faces of the full sized "painted" nodes are exposed and don't look very good when facing the uphill side of your road. I simply added existing "paint" textures to front and rear faces of three nodes. The sideline had to be rotated 180 on the rear of one node. I think it looks polished and less confusing when using the road.
Attached is before and after, showing the difference. Hope you will consider pulling.
