very nice result
the only problem is the low speed/high noise for this method to visualize lightbeams...
but hey... I got enough time

Hey Ono, is the sun outside the SSS medium or inside? Is there a difference at all (out or in) ?

thx.
The sun is 'outside' the scattering medium.
The scattering medium is contained in a sphere with radius 20m, approximately the size of the scene.

But it doesn't matter, if the sun is!
It's at the sky-sphere, isn't it?

@ drBouvierLeduc:
Basically, it's weak SSS.

Yes, the effect is from weak SSS/participating media (uses the same code).
