I have problems making glass...I used vex glass with no luck:),

I tried Mario Marengo's shader (from cornell box thread) but it also produces some strange results - glass blob renders half opaque, no matter how deep tracedepth is set.

I'm not very experienced shader writer and I look for some help.

Hi, Peter!

Send some example scene, maybe with test renders, since I don't understand exactly what goes wrong. Rendering glass is always kind of tricky, since it's depaneds on your composition what kind of alpha, opacity etc you need.
