Quote - This is precisely what normal maps are for . . . They can't capture the overlap, but they do produce a much more complex (and realistic) geometry for this kind of situation.

Poser Pro supports normal maps, but I don't think Poser 8 does . . .

Neither can represent a sponge surface - the best you can get is a cratered surface.  Bagginsbill has me convinced that normal mapping offers no practical advantage over bump mapping in any case.
