Help with Geometric details

Good to know.   Yeah, I know 40M is way too big, was just curious.  Probably I’ll be export models out to bring into z-brush, or some other program, and bake out displacement maps to put on a lower poly model.  As an aside,I have a feeling I’ll need to actually learn z-brush finally, to smooth out the noise in these models instead of getting it sorted out in the scan–sigh.
