For example, if the spaceship lands on the road, it would be nice if its 
light illuminate it - actually the lights should illuminate *everything*

Diffuse lighting without shadow testing is meaningless when the shadowless 
keyword is not used. Why would you even ask a question like that?

answers are sometimes like this when people formulate questions that are not 
100% precise.)
