Realistic Glass Material
 

I'm working on a VR training simulator for medical use. We've got a lot of glass vials and IV bags (and a few windows) in the environment. So need to get as realistic of a glass material as we can manage.

An older version of the project an be seen here:

We're using LoD, baked lighting, normal maps and transparency maps. What's the best glass material we can manage in Vizard beyond just turning on the transparency?

If you are using 3ds Max and the OSG exporter you can replicate a glass material using a standard material with a diffuse texture with alpha channel. Use a circular alpha channel and Spherical Environment mapping coordinates in the material. This will give you a "fall off" opacity effect. You can add an environment map in the reflection slot . Attached is an example of the glass material.
