If global ambient is linked to the strength of your light sources (or
number thereof) via something similar to the "ambient
0.3*Light_Strength*light_num", then the induvidual ambient of objects
doesn't need to be played with as long as you also take into account the
proximity of the light sources to the object (as someone mentioned
earlier: in space, there is very little ambient) when giving these
objects ambient values in the first place.

I personally prefer setting ambient to 0 and let radiosity take care of
all this stuff.  But then again, I have the horsepower necessary for it,
so ymmv.
