I'm using POV 3.6 and the Galaxy-include(s) by Chris Colefax. It worked well
with POV 3.5, but now I don't get any black background - instead what makes
a galaxy (space) is placed on a [white|grey]-squared background... seems
transparent, I guess. Why?

How can I get back a background which looks a little bit more realistic...
e.g. black? I know that the universe is transparent for any kind of rays
since app. 14 billion years, but it doesn't look very nice if rendered. ;-)

Or is it that I'm switched to WinXP recently? 8-O

Thanxalot!

Tom

Somewhere in your include file you've got output_alpha set  to on. If you 
switch off alpha output then you get your classic black background.

The grey white squares are showing the transparent parts of the image file.

It's unbelieviable! You're right!
