I try to use vex_glass shader and it worked just fine up to the time that I want to render transparent shadows with it. I did a bit of research in VEX and I found out that in order to make refraction the opacity is set internaly to 1. Now can someone please tell me how can I use it along with texture filter shadows. I try to put another paremeter for the opacity and turn it down but now the glass obj, looks washed out.

many thx
