Quote - ok, now I am baffled. I just modeled a drink prop and created the glass with a seperate interior to turn into liquid, yet every combination of water I use does not show up. Clear, pool, any color, I get the glass only and the alpha is at 1. What you are seeing in the image is close to the look I was going for, but I had to turn the interior liquid part to glass to get it to show. Any ideas? Is this a shader issue or a modeling issue?

 

 

 

I posted this diagram in the old DAZ forum so I guess I'll post it here also:

This is how I set up my liquid in a glass models

Its all about the way the normals are setup. Unfortunately if your model is not setup that way you will need a modeling app to fix it.

 I use hyper realistic glass, and the appropriate IOR for my liquid of choice. You must be careful lighting this as usual to avoid those pesky fireflies.
