Hi
I can set up a room with some emitting planes, and it renders fine (no lamps needed).
The only thing I’m missing are the shadows. I must be missing something fundamental.
Any tips?

remember that the radio calculation uses vertex colors. the mesh on which the shadow casts on has to be [heavily] subdivided.
