Hasta La Motion!

Is there a way you can put a light inside a sphere and have it light up the inside of it? It seems that only directional lighting works in spheres. I guess the only reason you would want to use a sphere for a background is if you were doing a sky projection in which case you would be using directional lighting. Nevertheless, I tried to use one for an indoor setup but it would appear that both point and spot lights have to be outside the sphere in order for either side of it to light up.

Sorry if this is a stupid question. I’ve done a few things in Nuke’s 3D system out of necessity, but this is the first time I’ve tried testing it thoroughly
