Help : Combining maps in the material editor

Neither bumpmaps nor normalmaps are supported in this engine. That's probably why you didn't find anything.

If by colormap you just mean texture then that's done too, I assume. Just import and apply them.
If you mean something akin to an overlay this effect can be accomplished with "Combiners". This should help you out on UDN.

Specular maps are applied to textures via "Shaders". Again, UDN is pretty comprehensive concerning this.

If you need an instruction let me know.
