Hi there, for my new product I need to have a real glass material on my wine glasses, but I'm so bad with the materials editor, so my question, are there any good tutorials out there, to learn me how to do glass, or can anyone tell me, because my trials looked more like transparent plastic! ;)

This should tell you everything you need to know:

:closedeyes: Well, looking to make money from free advice is kinda a conflict of interest; can we see the WIP, whom will your Beta-Testers be?

:mellow: The distortion of light, throgh glass, is known as Refraction.  Which is very much like Reflection, for Poser as you're assuming an encompassing environment(Geometrically,) when a default Poser scene does not offer this.  The outer limits of a Poser scene are void.  JUst like ou needed to add light, so do you need to add physical objects, at every point around the glass, for the glas object 's material to react with.  A Sky Dome is really easy to achieve this, addition to a scene, quickly; and would probably improve your current progress. 

:biggrin: Clarity of jewels' is measure in their Refraction Index.  There is  ot o Poser know how behind incororating  these values into Poser Materials; be it glass, plexiglass, ruby, emerald, diamond...

Thank you very much... yeah, i know, well... every vendor has learned it  somewhere...maybe bought books, read tutorials or kept asking questions, like me :p lol...nah I seldom ask for things :p

Just FYI - a setting for (standard) glass, brought to your very door:-)
(Please excuse the degraded pic - jpeg and all that).

You can probably get away with less than 4 raytrace bounces (minimum would be 2 for any degree of realism).
DON'T add any transparency. The refraction+reflection will take care of that.

Refraction index for "standard" glass is approx 1.5. Values vary for other types of glass (crystal, lead, crown...) but for everyday stuff, 1.5 is a very good near approximation

These may be of interest concerning refractive levels...
