Disable auto shadow for specific objects?

How would you go and disable the automatic shadow, for example the I have a sphere and the back part is shadowed. I currently have 8 Planets with auto shadow, receive shadow and cast shadow, I cloned the planets and the clones are now a part of my main camera as planet button, click and visit the planets. But when facing the star, the planet buttons are totally blacked out, what I need to get rid of the shadows, I can’t change the material cause that will mess up the planet material also.

Thx, David

You could put a ‘flashlight’ or ‘head lamp’ facing into the scene to give it some light when on the dark side. You could bump up the ambient light when on the dark side. You could just set those shadow flags on the planet’s renderer to false when on the dark side.
