No you didn't say Poser couldn't do good glass, you said Vue's is better. Poser 5 has every thing Vue has to create glass plus it has refraction (Mentioned by Cheers above) and it has translucence two key properties of glass. So with enough playing with it, you can get better glass then Vue can do. :) Of course you will still be looking at it under Poser's lights that are not as good as Vue's. :D
