I am making a sort of front desk, for a largish theater. However, it is suffering from some sort of overlap of the polygons that gives a graphics error when rendering. You can see it on the close end, where the counter curves sharply. I made the desk by making a counter section, tiling those end-to-end, splitting it up a few times to increase poly count, and finally deforming it using a curve modifier.
Can anyone suggest a good way to remedy this, or a better approach to take if I need to remake it?
