I tried rendering the Blink-scene, with or without radiosity, and when rendered
with UberPOV beta 7 x64 the yellow ball has a shadow but looks strange with
radiosity on (I used 'no_cache'). UberPOV beta 8 x64 produces no shadow for the
yellow sphere no matter what, but when radiosity is on the result looks somewhat
better than with beta 7 (bar the lack of shadow).

A question about the Blink-addon: can I use it on a camera or a light?

@Clipka: I have 5 testrun png's, 400x300. If you want to take a look at them, or
the POV-file, just send me your e-mail address.
