I'm glad some finally said this.

IMO one of the best methods of faking radiosity ( in Bryce ) was one developed years ago ( can't remember who ) with B4. It involved the simple procedure of putting a radius light inside the radiosity object. Then make the object slightly transparent 2 to 5 percent. Set the light's color to what ever was needed ( if the radiosity object was gold, then a gold color is used on the light ). Since the object is only slightly transparent, it appears as though it has no transparent properties. But it is enough to let the light leak out, so the objects around the radiosity object collect the light. Giving the appearance of Radiosity.

And the render time isn't bad.
