Hope this doesn't suffer in translation.  ;)
There's some dark splotches on the lower left side, maybe reflection? I didn't
check, wanted to go ahead and post this.

How long have you lived there?
And English is a Germanic language.

It seems, with my graphic program I can work only with one layer, if it
comes to 16bit. Cannot create any additional layers when in 16bit, and I
would need, in order to crate a similar pattern.

I use Photoshop v7.0. That is the reason, why I could not create the
image you suggested (and I agree on).   :-(

Will create a new bump image, but it will be again 8bit. But I create it
as a smaller version. Hoping for the best.

Clipka, I created a new, more contrasting bump image. I dream to get
something like your result. My Photoshop 7 does not allow to work with
multiple layers if the mode is 16bit, thus I had to create it again
(sadly) in 8bit.

Well, quite some time. Speaking English is the easiest for me. Listening
to English takes on a bit more concentration, but I can manage. But
reading in English takes on the most concentration, if I read too much,
i lose the contents and nothing reaches my understanding anymore, after
some time. That is how i would try to describe it.

English and German are not really similar, even if the modern English
has some of its roots in the Germanic language of the Saxons. Some parts
are Celtic, some parts are French, and some are even Latin (beside
French a 2nd Romanic language). But that is not so important. Important
is, how similar languages are. Not enough for me, to avoid this problem. :-

All I can say is I can render your exact scene using your bump map file and see
how it should be.
However, there is trouble with the image_map. You say a "texture" name for that
one, yet didn't give another, so I used the same bump_map file for the texture
too.
I can see the shadowing on the surface, but the contrast is now so much I lose
sight of it in the darkest areas.

What I tried, again, is remove that image_map from pigment statement and
replaced with a simple:

color rgb 1 // plain white

Rendering posted.

And I was confused at first about the rounded shadow seen on the top left side
of balloon.
That was once again the 'parachute' piece, you don't actually see it until
moving camera farther away; I got rid of it before by replacing 175.001 with
MyRadius+0.001 in the SDL part:

#declare LowerBalloonShape = difference
{
 sphere { < 0.0, 0.0, 0.0 > MyRadius }
 cylinder {
  < 0.0, 0.0, 0.0 >,
  < 0.0, MyRadius+001, 0.0 >, MyRadius+0.001 } // instead of y*175.001
 scale < 1.0, 1.5, 1.0 >
}

I made the balloon HOLLOW (instead of a difference). And removed the
TRANSMIT keyword. Looks better. But not getting any bumps. Made also the
top a bit flatter again 8as it was before).

Are you able to reproduce anything that looks like Clipka's balloon image?
