Rhino V-ray Viewport

[gedsta]

Hello,

 

I'm experimenting with V-ray and Rhino and I'm quite new to this. The problem I'm having is how do you view materials in the viewport? Standard materials like brick are fine, but when I apply glass, there is no transparency, which is a bit annoying, is there a way to achieve this?

I have found a way to do it:

 

Does the command ~3:40 onwards.

 

The tool is: render preview viewport, the only problem I can't find it it in my Rhino programme, anyone know what may be the problem?
