Hello out there!
My problem: shadowless lights and polished surfaces don't work together
I'm sure I already read about this some years ago when I started using
PovRay in v2.x. However, I just encountered the phenomen again. When you
define a scene and use the shadowless keyword to prevent the light
source from casting shadows this lightsource will not highlight an
object with a highlighting surface finish as e.g. phong. Is it a bug or
a feature? I don't know but since shadowless lights are originally meant
to "fill up" the light in the scene it might be a feature.
I'm using shadowless lights because I want to render a complex scene
representing a crystall lattice with some 10000 atoms in it. Not using
shadowless lights inevitabily leads to the inner atoms being always in
the shadow of the outer ones.
However - even if it is not at all scientific but perhaps artistic - I
might like to have polished surfaces with small highlights.
Is there anyone who knows a trick to solve this problem except for using
one lightsource for every atom???
You can see an example of what I'm rendering at
