Thanks man for the reply!
Well, i need tweak more the options, this is with glossy (fast config)
Looks better, but I feel that still lack. The only thing i hate is the time to see a good render (20 min for this image in a i5 2500K no OC, no GPU). I read that changing the type bidirectional render other things could change. As I recommend changing this section to get good results and a little more quickly?
And suggestions regarding the modeling of the lemon, texture and material, lights, etc, are still open
Thanks so much!!
EDIT: 1 hour, 40 min of render
EDIT2: The bump is in reverse, looks rare
, so i changed: (before: -0.02, now 0.02), and the renders looks good! waiting to finish, and more tweaks late. I'm a little busy now!
