Thanks for the replies, both of you - very helpful. No the transmission was the default of about 8/10 and the odd thing, which made me think it was an anomaly, is that the same accurate/ simple glass textures have excellent transparency/reflection qualities when looking through at normal vectorworks objects. I arrived at something similar, if cruder than yours willofmaine, using a mirror shader for reflectivity and plain transparency of 8, very similar in effect, but still lacking the nice specular and edge effects of the proper glass shaders. I'll report it to Nemetchek as a problem. Thanks again.

Hello everyone, Does anyone know why you can't see a renderworks background through a glass shader (simple or accurate) using final quality renderworks? You can see it though a texture which uses plain transparency, but that's nowhere near as nice. Here are 2 images of exactly the same setup, the first using glass (accurate) and the second, plain transparency..
