Hello, I am drawing several surfaces which are offset from each other in the y direction. The surfaces represent layers in the earth, and they do have relief on them. All surfaces use the same material properties and all surfaces are illuminated by the same directional lighting, which comes from the -1, 1, -.6 direction (above and to the side a bit).
All of the surfaces show shading as expected, but whenever I delete a surface, the remaining undeleted surfaces will show visibly diminished shadowing effects after the deletion. If I then add a surface, the lighting on the surfaces that were visible prior to adding the surface will show visibly enhanced shadowing effects. It looks to me as if the lighting is being applied to pixels that are hidden as well as to those which are not hidden, or something like that. Has anyone else seen this and can anyone suggest a workaround?
