Ok, I am officially frustrated. How the heck do I get a spotlight to work? Everyone I have dragged into my dungeon is red and will not cast any light. Anyone have any tips?

I think I have an answer for you. Been going nuts on this myself. You might try right clicking on the render window and going to Render Window Properties, and then go to the shaders tab and make sure shadows are turned on (all of the spotlights are shadow casters).

Thank you!
