progressive caustic

[ronald_a]

I am looking into progressive caustics and it seems I can't get any usable results out of it. Before I send any example scenes I was wondering if this is supposed to work or if this is still beiing developed/implemented into vfh. I am asking, because it seems when switching to progressive caustics, all the settings are being greyed out and from what I can tell from the docs of max/maya there should be at least the "search distance" available. I did stick to all the (other) suggestions from the docs, but getting some good looking caustics (waterdroplets on a surface) does not work (well it does something, but it looks strange and seems to render pretty long).

If you could confirm that this should work, I am more than happy to prepare a scene.
