If you use Surface->change-vertex-order and then resize/undo to force normal recalculation (must fix the change-vertex-order code to recalc normals...) that should bring color back to those surfaces.


Alternatively, triangulate, or divide up the large polygons.
Great. Thanks Andy. I was closing in on something related to normals.
