Ok I finally got it (thanx wacky, not only for this post, but also for all tips you usually share). I am posting three images and attaching my test scene (max and psd) so it could help newbies like me to understand the proccess.
I have some [beginner to intermediate] questions
1. I had to turn off the Raw Reflection filter to achieve the exact same look of the original render, is it normal? (as you can see in my images, with Raw Rflection Filter ON, glasses look darker)
2. I used TIFF 16 bits images, is there a better format option?
3. The composition looks with a thin black line in the edges, is there any tip to avoid this?
Thanks!
