Hi all,

what I don't like in my picture is the metal, and the glass is not good
either.
Anyone has a tip?

The picture is done using Rhino, Moray, POV3.1.

Thanks,

Nice pic.
I would lower ambient to 0 for both the metal and the glass. Then try
lowering the diffuse as much as possible for the glass (something like 0.05
or 0). I would also increase the brilliance value of the metallic texture.

Have a play with the ior value.  It's a good looking image so far.

The metal seems awfully bright to me, if it's meant to be polished
stainless steel or something similar. If reducing the ambient to 0 as
another poster suggested doesn't help, consider subtracting (current
diffuse value * reflection value) from the current diffuse (IOW, if the
metal has a diffuse of 1, and a reflection of .3, then make the diffuse .7).

This was a good idea for the glass!
But the metal still looks too perfect...

I have to try.

An other strange effekt:

The ribbles in the glass are not the same. Is there something changed in
3.5?

Thanks for the input,

If the ribbles are a normal, you may wan't to look at "noise_generator" 
in the 3.5 doc.

I'm not sure how the metal is "perfect" and how you want it changed. Did
you want it to have more of a brushed look, or the splotchy look that
sheet metal has? Give it some texture. Did you want it less
glossy-looking? Play with the specular and reflection settings...
