Hi Mark,
Bump mapping can be acheived using DOT3 texture combine mode, but unfortunately there is a bug with multi-layer texturing that I haven't been able to circumvent yet, so you can't bumpmap something that already has a texture on it. Hopefully when the source is released we can fix this :-)

Fair enough. What about normal mapping (ie, an RGB image where pixels represent a normal vector at a a given texture coordinate)? This strikes me as an extremely useful feature which is starting to get wide usage.
Post when the bump mapping bug is squashed. :)
