If this is true, the effect should also occur if i change the pigment
of the sphere from <0,0,1> to <0,1,0> or something like this. But in
those cases nothing happens.
I believe Christoph that this is a minor bug but it is a very strange
kind of bug. I would really like to understand why this is there.
And maybe it is possible to change this bug into something usable.
I don't think that the ambient part in the material section
superseeds the global value. I think normally the material ambient
is multiplied by the global ambient light to give the initial
brightness of the material (with adding direkt lightning).
Normally this seems to be true. But in this special case it is
a little bit strange.
There are some tutorials out there about radiosity but i have
never found one that decribes the mathematics behind this in
MegaPov or Povray completely.
Ciao, Udo
