Would you just put a radial light into a glass sphere? Any ideas? Thanks.

You can do that but the render time will slow down, especially if the glass sphere's overlap each other. Or you can put one inside a sphere with a transparent texture. Or you can just put sphere light objects where you want them and enable "Visible Object" and give it the color you want (or a texture gel).

Used a plain red sphere with transparency set to like 50% with a light inside at 5 intensity, red it color, and a ranged falloff of 1. I'll have to play around with the color some, but it looks ok. Thanks!

That works. The "visible Object" selection on the light object is faster on the render but harder to control on the falloff. This is kinda like what I was getting at with the first part of http://www.annsartgallery.com/suntut.html

Some of the Bryce4 material presets use an alpha channel as the ambiance, causing certian areas of the material to glow in the dark....the mat called 'gilded cage' is a good example. They don't actually give off light, shadows just don't effect them. They render fast, too....

The ambience thing is great! Thanks.
