Wine glass

I want to make a wne glass as realistic as possible, rendering withYafray, but the caustics look weird to me. Can anyone help me a bit with the caustics?

Would love to, but a posting of the image you have now would help so we have a clue as to what is happening.

is it just me or cant i see a pic!!!

nope not just you :s

The glass maybe a bit thick in the bowl area. This may account for wierd caustics. Also what cdepth do you have set in yafray?
