Okay, now this leaves surprisingly few possible explanations. I can only
come up with the following:
- You might be using a rare and buggy version of POV-Ray.
To check this, I recommend you post the exact POV-Ray version number
(and let us know which operating system you're using).
- You might be using a different scene file and/or bump map image file
than those you posted.
- There might be a relevant line break introduced in your post of the
scene file that we've been overlooking.
To check these two, I recommend you temporarily rename your scene and
auxiliary files (image file and bump map), then try to re-create the
scene from your own postings and render it. You'll get parse errors,
make sure to fix only those actually reported.
- You might be using low-quality settings (`+q7` or lower).
To check this, I recommend you post the message output of the render,
and/or run the render with `+giFOO.INI` and post the generated FOO.INI here.

A long way off the record.
642 at the last count, in OT.

Has anyone collect Sven's code? I don't fancy going through the thread
to piece it all together. And I've not been following it closely.

This is the latest, with my amendments. See also the attached images I used.

The light sources I was suggesting were the lights at the bottom of the balloon
- in the video. Because spaceships only ever visit Earthlings at night in
isolated, unpopulated areas.
And it makes for dramatic lighting.
I think that for clarity and accuracy, it might be advisable to package all of
the files into a ZIP and post it in a binary thread so that everybody has all of
the same pieces to analyze. Unzip to a subdirectory, and then there shouldn't
be any question of what files are being used to generate the render.

Thanks Thomas.
The results were as expected. The shadows showing.
But is this expected? It is the top of the balloon.
[Drat! I can't put them inline.]
Using Sven's original code. I imported it into Bishop3D correcting the
errors one by one. Using the image maps you supplied. The second image
is directly from Sven's code.
What concerns me is:
image_map { png "H:\My Documents\My Pictures\POV-Ray\Space - Launcher
- Balloon - Type 001 - Moon Runnings - Balloon Texture.png" }
Are those spaces and dashes part of the file name?

How very true. :)
Did I ever tell you about the time I stopped off in Roswell for lunch? I
regretted it, I can tell you.

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. :-
