I've done a couple in my new 3D textures album (link below in my signature). They are only examples. If they work, and if you want I can probably make a reasonable normal map from an image/texture in Genetica. The limitations I've discovered so far are that if the colour part of the texture is very strong/contrasty it affects the normal map somewhat because the contrast is misinterpreted as part of the actual physical texture. That's why there are two versions of the cathedral tiles in the album already.

Let me know if you want to try it
