I recently discovered this random light-patch-brightness as well (while
animating my 'city buildings.') I thought it was because I had used the rather
crude default values for radiosity. Saving and reloading the data sounds like a
good idea.

I need to read the up-to-date documentation; haven't done so in a long while.
I don't think I've ever tried using radiosity in an animation, until now.

Thanks for clarifying.
