It has happened to me on occasion.

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.

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.   :-
