In the mentioned image "WIP-Sculpt", the reflection of photons cause them
to gradually change their color (into something more greenish, because
the surface-pigment is rgb <1,.5,0>, and at some point, I get lots of
red and some green photons). I wanted to have only orange photons,
not ones with changing colors (looks somewhat strange, even if
calculation-wise correct). But the scene itself should be lit with white...

I could try that, good idea, though I think I'll leave my Sculpt finished
now...

Yup.

I already mentioned what I wanted above, so I won't duplicate
my sentences (#if (Words=Said) #avoid Spam #end).

Thanks for the answers, it helped (or will, to be honest).
