Hello

I have set up a basic scene but I'm having problems with the lighting. I haven't put any lights in the scene as you can see from the code below and yet objects are reacting to light. I presume this is the default ambient light because adjusting ambient light does adjust the affect.

However, I don't understand the effect that I am seeing and was hoping someone could explain what is happening and why.

If I remove the SCALE OBJECT command then all the objects in the scene are equally illuminated but scaling the object up in size makes it darker and scaling it down makes it brighter. I could understand it if it was getting brighter because I was moving it closer to a light source but that isn't happening.

1) Why does SCALE OBJECT affect lighting?

2) How can I scale an object and keep it the same brightness as it was before scaling?

Thanks for you time

Anyone?

I'm sure there is a simple answer but it has me confused.

I have experienced some of the same problems. I do know the answer to one of your problems: Light 0 is always automatically a directional light facing down. Hide light 0, or change it to whatever you want for a light, to rid of this effect.

It doesn't matter if it is confusing, as long as it works
