Is it possible to get shadows in the scene composer?

I’m trying to construct a scene with the scene composer. I figure out how to create a .j3f file and show that in the scene with the eye button. However the main thing I’m really trying to do is to see shadows (to help with lining up my lights and stuff), which for some reason does not exist in the FIlterExplorerWindow. is there any way to do this?

The eye button on top of the scene viewer.

i guess what i should have specifically said, is Directional Shadows. you cant add directional shadows to the .j3f file, it only has ssao.
