Self Illumination Material in Beast Lightmap

I try to setup a scene similar to this youtube tutorial video. I have no problem baking a basic scene with a directional light. However, I have problem baking the light from a self-illumination material into the scene.

I have tried a lot of different settings; and I create a new scene like in the video, but I cannot bake any emission light into the scene. What have I missed?

Lightmap Setting

As shown in the 2nd screen shot. I have baked a lightmap (AO is present), but the emission of the ceiling cube is not baked.

The emission value on your material is set to 0. :wink:
