...
Also, one thing that should be noted is that in putting in BumpTexture and InvertedBumpTexture texture types into gTexManager, both BumpTexture and InvertedBumpTexture both use trilinear filtering only because bilinear looks horrible. You can really see a sharp contrast between mip levels.
And, the bump texture I provided is detail1.png with a contrast filter on it using MS Photo Editor, and I noticed as I zoomed in that there are seems long 1 side. So, it tiles perfectly in one direction, but not the other. But, you can't tell unless you zoom in. So it may need to be replaced with an actual bump texture example.
