Hello everyone!
Do you know if Karma is planning to introduce caustics (via a photon kernel or something similar to Octane or Redshift) in the near future?
I work daily with glass renderings (lots of whiskey), and to get caustics I have to rely on Octane or Redshift, which is a real shame because I really like Karma's integration in Solaris.
But for now, it's just not usable for me...

Well... they say caustics are supported but no one has seen one!

i tried the caustic of karma in h21,it seems goog enough, and of cause it will be slower than fake caustic.
you only need check EnableCaustics in karmarendersettings. if the caustics not brigh enough,you need increacing DiffuseLimit and ColorLimit.

they can be all over the place, indirect diffuse, indirect sss, indirect volume

or overall something like this: C[DV]G.*[LO]
