Well, I had a little time today to mess around with Radiosity some more. Reddog9 is right, Yafray is an actual GI renderer, while Blender's radiosity feature is only a fake. But 1. I hate Yafray and the hours and hours of my life I have wasted waiting for test render after test render to finally get it to look like I want, and 2, with the ability to turn the radiosity solving into vertex colors, and with the texture baker, I think I might could make some really cool textures for my models.

Anyways, after getting involved in another thread, here is the 3d view of a default UVsphere after applying radiosity with the default settings.

Notice the deformations on even the flattest of flat plane! But the main problem is the concentration of tris at the top of the sphere. In the Radio Tool tab, I used these settings

Elmax:20, Elmin:10, Pamax:50,Pamin25   and got this...

This seemed to cure almost everything except the tris. Note that this sphere is not subsurfed, only smoothed. The solving time was 302375ms, which is kinda long for me (I am impaitent) but not too bad. I want to try more stuff when I can, and Ill post it. when I do.
