    Rendering Clear Glass

    This is a very minor issue, but I am having trouble getting clear glass to render properly, and wonder if anyone has some help to offer.

    The attached image shows what I have so far.

    The render settings are:
    Abbient: 34%
    Diffues: 31%
    Specular: 90%
    Shininess: 100%
    Emissive: 0%
    Transp: 99%

    Raytrace Settings
    Reflectivity: 25%
    Bumpmap: None
    Material is Translucent: No
    Transparancy filters llight instead of transmitting it: Yes

    I cannot find a setting for refraction, nor any way to affect refraction with the other settings. I know Raytrace has a refraction setting, but there does not seem to be a way to set refraction from Chief.

    The model I am looking at is from TrueGlass, an add-on to Maya. The inset in the attached image is a TrueGlass rendering. As you can see, my glass rending is far from perfect. There is no refraction at all. It's just not realistic.

    Any advice from you rendering experts would be appreciated.

    Chief miss refration and caustic. Your sample render have caustic too.
