can you re give the scene with change to me?
with my setup after 55 min the render isn't end....
medium setup

excellent work!
I too have experienced a glass without success
I will treasure your experience

mmm i'm to this point.
now i've all caustic in scene!!!

Thank you Nico for letting us test your scene. Here is the test setup in return.

Maybe too much effect but i wanted to show that youre not limited to lights. This is an HDRI image of a window mapped on a environment-sphere surrounding the setup and as you can see the window and it's colours are seen in the caustic pattern. This is 20 million photons.

Very nice caustics Silver. I like the hdr test.

optimus!!!!
thank's silver...your render scene is very very fast.
now i study it

silverlw, sorry for disturb but when you use a hdri disabilities the light or use a small valure of brithness for imageworld?

I dont use any lights at all, only an HDRI mapped on a sphere surrounding my objects i want to lit. You CAN use imageworld if you want but then you need to use lightmapping instead of photonmapping. Here is the scene again and i have included the hdri.
