I am in the final stages of putting a visual together and I am populating a servery with glassware. I am having a really hard time creating a realistic but fast to render material.
Maximum refraction, falloff in reflection, affect shadows turned on. Make sure its got a thickness of between 5 and 10mm and a good environment, and youre good to go.
I’d put a slight bluey/green tint to the fog too, but depending on the thickness of your glass or scene scale you’ll need to mess about with some numbers.
