Hi guys,
Why do i get edges like that? Using which parameter can I fix it? Is it conected with light? Thanks! I just switched from vray 1.48 to vray 2 and i get this… 
cheers
Since I can’t really see what is wrong because the Image it too small I would hazard a guess and say that your render settings are not high enough for Vray to add anti aliasing to the edges,
you should follow this tutorial that Vlado did on Sampling: https://www.youtube.com/watch?v=tKaKvWqTFlw
Hope it helps.
You’re the man! Thank you, it helped 
So i had to set max subdivs in adaptive dmc on 24 (insted of 8, which was enough in vray 1.48) and it’s much better now. Thanks once again!
No Problem, I’m glad it helped, I just realized that you are rendering with Vray 2.0 and so the wokflow video I sent you would only work to an extent
( unless Chaosgroup added the global subdiv multiplier to Vray 2.0 )
If you want to understand he sampling better Grant Warwick has a great video on the subject and will really give you a better understanding of how Vray works.

Thank you very much. There is global subdiv multiplier in 2.0
