Dan- zbrush sounds awesome... I know folks using it for normal maps in the unreal3 engine just for this reason!
polybump is the only one so far that I can get to work in A6, as true normal mapping...(see my post in showcase, the head is true normalmapping...)
It actually imports my obj's (or were they 3ds?), with the right uvw info and creates a normal map that can easily imported into MED in sikn2 , and matches up perfectly. The poroblem with ATI's and nvidia;s melody (which is amazing), is that the uvw info doesnt carry over...thats important to me because I texture bake in max, and need those uvws! if anyone know a way please share, since polybump is just a demo and unusable... Melody gives simply amazing results in the viewer, now if i can get it out and keep my uvws...Doom3 quality easily. When I have a 130,00 poly head next to a 700 poly head in melody, IT LOOKS ALMOST EXACT...
i'll post an example image later, you can barely tell them apart.
