I've done some more searching, and the problem appears to be image urls
having "../foo/bar.jpg" stuff, when loading the file
"c:/beep/boop/usingbar.wrl" having "c:/beep" in the pathhandler.
Then the ImageFileHandler fails to parse the file type correctly.
Loading from boop (i.e. issuing that path to the pathhandler) solves the
problem.
Tricky...

P.S. Pardon the silly example names, I've had a busy day... :)

I'll get on it on monday and see if I can find anything else that
pinpoints this issue a bit more, otherwise I'll put the stuff on the web
for you.
Thanks for looking into it!

Hi Marcus,
just tried it with a much longer pathname than yours this worked fine
for me. Can you upload your file somewhere so we can reproduce this?

Hi again,
I have noticed some strange bug when loading files. If the path too
long, then things go wrong (textures disappear and/or no polygons
loaded).
Loading a file such as
'C:\Misc\Styx\thorax\Heart_20050825\Parts_heart\r_atrium.wrl' does
not work in OpenSG (1.4), OSGSceneviewer (1.4) or VRED (0.97).
However, 'C:\Temp\Heart_20050825\Parts_heart\r_atrium.wrl' does.
Also, if I load a incorrect file in vred, I can't load a correct file
without restarting.
I suspect a buffer-overrun in the path length, especially if the
vrml-file refers textures (i.e. ../images/aorta.jpg is the case in
the above file).
I couldn't find any bug on sourceforge, but I know there's been some
postings on path handling and such, so someone might have looked at
this.
Can anyone confirm/deny this?
Best Regards,
/Marcus
