Emissive material not emitting light

    So, I've been having this problem ever since I have started using Unity. I have followed all the tutorials, looked at probably all the threads with the same problem, however I cannot get it to work. I have created a new scene where I created a plane with a sphere and a cube over it.

    I created a new material, made it red, set the emission to 1, and put it on the sphere and the cube. I made all the objects lightmap static, set the material to baked lighting, and enabled auto baking. However, although the objects increase in brightness, there is no emitting light onto any other surface. I even cranked the emission up to maximum (99) and recreated the material, however there is no change. I cannot for the life of me get emissive materials working.

    I created a barebones project of what I did here (click slow download):

    I know this isn't a hardware problem or something like that, since I can get emission working in Blender just fine.

    I have found that if I set the lighting priority of a bright material (blue, white) to important, and crank the emission all the way up to 99, then the object will emit some light.

    However, it is really dim. Even if I bring the ambient lighting all the way down, it is like lighting a small candle in a stadium. If I change the emission color to something a bit dimmer like red or purple, then there is almost no light to be seen.

    Now I have another problem. An imported object with emissive materials is not emitting any light whatsoever. I tried baked and realtime lighting, and the same methods I used for the cube and sphere. The cube and sphere can emit and receive light from each other, however the imported object is having no effect no matter what I do.

    Edit: Do I have to have a lightmap in order to have imported models receive and emit light from emissive materials? Everything except my imported models work with emissive materials, and the only thing I can think of is that I need to unwrap the model UV in Blender.
