Agree, though, I still don't get what all is happening there to get the
milky effect. On the overdone sphere - remember I'm testing limits not
going for any given look. Even the milky effect I found by using bump
sizes larger than what I think most would / should typically use in
practice.
I'm thinking some of the milkiness is coming from getting less overall
reflection because some of the normals are inverting and some not - some
we see more of the metallic effect in the result. More of the raw color
shows through.
The reflections which are there are no longer fuzzy though, which has me
puzzling. A significant number are pointing away / against the raw
surface normal sphere rather than mostly being aligned. Guessing we are
hitting some limit where maybe the perturbed normal gets ignored or
something except maybe for being inverted. I don't know! I'd have to
spend more time in the code to figure it out. The question is rattling
around up there in my empty space - maybe the reasons will fully come to me.
I'll attach another image using again the milky effect, but on three
star mesh include stars. Appropriate given Mike-the-elder was about on
these newsgroups again recently after years away. His star mesh code /
and version of it, I've used quite a bit over the years. Anyhow, the
milky look is a little different than with the spheres I think, the
environment is different too...
