josepicos, Pat Pattle,
yes, this is what I need.

Can you upload a full uncompressed (i.e. not a JPG) version somewhere?
And if you have a grayscale (a heightmap) version it will also be useful to me.
Thanks!

MajorMagee,
I've looked at JU 52 model you've sent me and moire patterns are indeed quite prominent there. They aren't related to bump mapping though, they are result of sharper texture rendering with my shaders. I can't do much about them besides turning off anisotropic filtering. However, without AF some details (like markings on WWI planes in WOFF) become very blurred at glance angles. So I'm going to add an option into d3d8.ini to configure AF level to personal liking.
