Well the old AMD came through again, 5h11m33s render time...detail.5...AA 3....1 and 3 on the GI with the button off.
I went back, remade the road maps and added a shoulder map which works O K. Still some tweaking to do to get more of the grass out of the shoulder, some should be there but there's too much now. I also discovered a depression which makes a nice stream so I have another version set to go with water which should make it an 8 hr render...LOL..A critique is welcome.. ...
