glass material

[rauzcasuz]

hi

 

Can somebody help me how to make a glass material, where the darker area had a total reflectivity and the lighter area had a total transparency. I mean if the shadows affects on glass there will be appear hard reflected and where the light goes through the glass it will be appear totally transparency

 

I’m using a vray sun and skylight in rhino.

Not quite sure what you want, but a basic glass material should consist of a black diffuse color (not entirely black, mind you), light grey in reflection color, check fresnel reflections, set refraction to something pretty close to white, perhaps 220 and check affect shadows. That should give you a nice glass material right from the beginning.

Here is an example of the glass that I want it

You might want to fiddle with a fall-off map in the reflection slot. Here you can adjust the amount of reflection from a perpendicular view (blackish color - little reflection) to a view almost aligned with the glass (whiteish color - muchos reflection).

Dear Rauz,

the image shows not 100% transparent and reflective where you show, it's a natural blend of reflectivity and transparency. You get such effect by adjusting the Fresnel values in material editor in general, can't comment on specific software like rhino, if it has anything different.
