Also, glass has a SLIGHT bluish tinge, so I use RGB=250,250,255. Cherry Jello might be 240, 140, 140.

Glass is a real light reflector - It has very bright, tight highlights. I crank specular up to 255,255,255, and hardness up to 255.

The color that you set glass determines the shade Imagine will give to non-perfect glass - ie glass without transparency set at 255 255 255.

Black ( 0 0 0 ) works well, since then the color doesn't cover up the image. You can experiment, though.

One last important attribute of glass is reflection. Glass reflects light a little bit, so should be slightly reflective. Too reflective, and the transmitted image gets overpowered. Think of a window- you see though it quite clearly without seeing much reflection. At night, when there is little light coming though, you can see the mirror-like qualities of the glass. Transparency should almost always dominate. Good value for reflection are in the range 30-60, and again, I use a SLIGHT blue tint.

Steve's cool transparent ball-

   Color =0 0 0
   Transp= 250 250 255
   Reflec= 49 49 53
   Specular= 150 150 150
   hardness= 255 255 255
   shininess=0 (CRITICAL)
