Well, if my isosurface were more deeply ridged, there'd be shadowed areas in the
photon maps that normals wouldn't produce. But this probably isn't happening
here, I ended up with very shallow features.

Aside from that, I just assumed that the normal block wouldn't be used when
applying photon maps to surfaces. For no good reason, other than that normals
aren't used in radiosity unless specified. I can't find any mention of it in
the docs. I'll try it later, then I'll know... :)

True. At least (in general) cheating with actual geometry is a little closer to
reality. But I agree it would seem to make little or no difference in this
case.
