Not surprising (to me, since I still think there is some issue in the area), that model is no better. The right side is darker than the left with what should be equal lighting. I'm going to make my own version now to see if I can fix the problem.

I had some similar issues when i was adjusting object shadows and adding extra light properties incorrectly. :p

I know this is far fetched but did you try deleting those objects and adding them again?

Yes, I tried that. It made no difference.
I ended up re-generating the bin with the phong gouraud shader option instead of no shading. That has restructured the UVs and eliminated the problem. It should have made it worse with such a flat surfaced object, but it fixed the issue. I've also been told that if you revise the polys to get a different set of triangles, that can also fix similar issues. It seems that BSP does not treat all configurations of tris the same, failing to get the normals right on some configurations. But that would be a more labor intensive approach to use only if all else fails. In this case adding shading worked, even though the conventional wisdom is to use no shading on such flat objects.

Most object programs allow for quads or other shapes besides triangles, which makes editing easier, but then it's left to the computer to convert them to triangles when you export. But computers don't have any common sense so sometimes the triangles are appalling, so it's no surprise that changing them helped.
