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 first pic was done with 3.1g, the this one (f3) with 3.5ß6.
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...
