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) ?

forgot to comment this:
it rocks!

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?

hey how works the medium with exr maps for lighting...?
i wonder.....ono can u make a test with this scene and exr lighting setup?

perhaps one of this free HDR Skys could be usable for this...

Good point ! Didn't think of it.

@ drBouvierLeduc:
Basically, it's weak SSS.

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