Well, the bump_map is polar-oriented, so I expect the creases to show up 
on the sides too while the top is fairly smooth (according to the map).

A question for Sven, but I think they are.

Sorry, I meant the cap on the top that was missed in the difference.

Indeed it is. Although they look suspiciously, a bit like file paths to me.

Like everyone else, I see no reason for it not to work on Sven's machine.

Not sure, but I would tend to say NO. I have only that one bump image.   :-

Yes, they are part of the file names. But they cause no error message,
as POV-Ray gives them straight to the Windows system, and Windows is
handling the file management.

Please use my balloon texture for the outside, and let us know, if you
still get bumps.

Yes, they are. No cause of any error, as Windows handles the file

Clipka, you shot the bird!

Okay, everyone: I herewith declare myself as a big fool!
I use POV-Ray for soooo many years, since around 1990 or so, and can you
believe it I just oversaw all the time of posting here, that I used:
QUALITY = 6
And did not even think about checking for the Q setting!!!!!
SHAME ON ME! I wasted so much of your all valuable time! But at least,
one more time the POV-Ray community has proven its great pioneer-alike
spirit! I owe you all my big thanks!
