Many thanks for your hints. Meanwhile I just started a second rendering with
higher radiosity settings and less brightness. Will see what happens first. May
it take four days... To close the gaps within the lantern would mean to dive in
an object laying around for more than four years at my "stalled" directories.
And my little lantern is not as simple a CSG object as it may look at first
sight. But to close the gaps should not be to complicated... I only would not
really like to do this, since they are there at the original. May be I just have
to fire it up and look at my garden wall. May be a snail passes by;-)

Best regards and thanks,
Michael
