To get back to the topic though, anyone else know how I might
reduce artifacts?  I have tried what raf said but I am still having major
problems.  Other scenes that I have rendered using lights as my main sorce
or illumination I have had no problem eliminating them(artifacts), but it
seems that the scenes in where I try to light up the space with mostly
radiosity generated light it is just blotchy or patterns develope on the
wall that won't go away.
