Architectural glass

Has anyone got any good tips for rendering architectural glass? Is it best to reflect a sky dome, or use an environmental map?

I am currently using an easy Vray glass reflecting a sky dome, but to no avail!!

I would usually do my glass for final stills in photoshop, but now I have switched to vray I am sure that it will give me better results.

Do a search on this forum :

“Architectural and Glass”

Lots of good knowledge in those threads.
