I made a model with the following properties:

my.unlit=on;
my.red=190;
my.green=190;
my.blue=190;
my.light=on;
my.lightrange = 0;
my.albedo=0;


I thought that this model reacts on no external lightsources,
but:
changing "sun_light"
impacts on the brightness of the model,
why?

I thought unlit means that it is not affected by
any external light.
