What is the best way to produce condensation on glass? Can it be animated? I have a clients beer bottle and glass that need that cold frosty look. I'll deal with the foam head on the glass later. Any tips would be much apprecited.

without more inforrmation, it's difficult to say. for starters, how close are you to the glass? and why do you need to animate the condensation? - you don't usually see condensation moving...

Glass Condensation ...

This is for a presentation for a global glass manufacturer. The two main objects are a glass and beer bottle on a countertop. Both objects will contain liquid. The glass filled with beer and a foam head, the bottle filled with beer. The animation will start with a extreme close-up of the bottles label and as you pan back the full view reveals both objects from about one foot away. Its a simple animation that achieves most of its impact from camera angles and creative lighting effects. Part of the overall effect I hoped to convey was through the use of the foam and dripping condensation on the bottle. Kind of like drawing on a steamed mirror and seeing the condensation run (drip) down the glass. They want it to look as though you just took a cold beer out of the refrigerator on a hot day.

ARRAN, here is a still render for approximate size and distance. No final lighting, caustics, dynamics, or any other effects. Also, the liquids have not yet been applied to the animation.

Maybe this is to simple but you could make some actual condensationdrops from geometry and aplly a waterdrop shader to it
You can also emit particles from the glass driven by an animated texture

Edit; Nice render btw user added image

That's interesting. However, I'm running Maya 2009 Complete. Is your method possible with complete or do I need unlimited? Also, I'm on a Mac Pro. Counting the days to the 64 bit "Snow Leopard" release. My life will be a whole lot easier.
Appreciate the compliment too!

Yup, it's possible. The quickest way to do it would probably be to model a drop, then scatter it around the glass. A way to do that can be found here. https://www.3dtotal.com/team/Tutorial...g/object01.asp

Good luck!
