No, no - that's not the idea. Besides, when one of your photon wants to leave a bar without going into another bar, it must go into a volume filled with air, the way you have set it up, either RadiationBlock or the World.

I suggest we continue this discussion offline, for now. I'll send you an email explaining how we/you can debug this further.

Thanks, Peter
