Thanks a lot! I thought about using a door or window. But this would mean
that I would have to do a landscape behind it.. And it renders slow enough
without.. ;-)

I had a photo as reference. This rather large and thick type of grass exists
and so I think, I will not change it.

I started a "full render" with radiosity at 800x600 pixel. It is rendering
15:45 now and reached only 37%...

No. The walls are created by a macro from Steven Pigeon. As far as I looked
at it, he uses superellipsoids to create the bricks.

I don't use any of these features.

I use this edited version..

I used the radiosity block from the insert menu. count is 35... Please don't
say, that I need to set to 100! ;-)

I am new to povray. I used it sometimes in the last years but never was able
to get good results. This picture is the best work I ever did..

Thank you a lot! I will post it, if my machine doesn't crash before it is
done.. ;-) If the result ain't what I wanted, your suggestions will
definitely proof very helpful!

I don't like the jpeg-artifacts but I will post jpegs from now on!
