the defautl scene comes with one lamp but if your remove this lamp
you can still see a black cube?
but what is the light source in the scene showing this black cube ?
i mean if you add some envir light then you still get a black cube with a white world
but light seem to be coming from some sky light
cause the sky and zenith are not really black but more like grey!
is this the light source for the cube or other source ?
and is there a flag somewhere to remove completely the sky light or you jsut make it black?
