  Box with no lights source (Message 1 to 4 of 4)

Here's the source for a box with no lights.  Originally made in
Moray, but then modified in POV.  If you uncomment the light source
and set the material for the ceiling back to DullWhite, you'll get a
more traditionally lit radiosity scene.

When I trace this scene in POV 3.1, I get a near black screen with the
white ceiling (and reflection of the ceiling on the ball) -- not even close
to what you posted in the binaries-group...

Make sure to render it with radiosity turned on. (+QR for command-line option).
If you're using POV for Windows, go to "Render"-->"Edit Settings/Render" to
enter command line options.

Also, if you cancel a radiosity rendering part-way through, you'll have to
restart POV to make it work again (at least with the windows version).

Ah, yes, that seems to do the trick! Thanks!

(I assumed that the source itself would trigger the radiosity)
