I heard that you could change the moon image too, but after checking the B4, B5, and Kitchen's books, there's nothing about that. I think if you want to change moon image, you need to use a sphere or a 2d circle object with the pic in it. I agree with you, Corel should put some attention to the sun/moon controls. I'd like to be able to increase the intensity of the moon and decrease the intensity of the sun.
