Thank you all for the kind words.
I hope that we can resolve all technical issues that some of you have.
We are still in beta, so a little bit of instability is to be expected - if you get a crash, please tell us in the bug tracker, even if it is not reproducible (those are the most nasty problems).
@Ace there is also this new article on SSS in Lux: https://wiki.luxcorerender.org/Subsurface_Scattering
I see your point about the lack of control over volumetric textures.
You can make a feature request on github or in the forums.
