Tanks. The "shadow line artifact" is now clear. I have to wait for a 
next version.

You're right. There seems to be a behavioural different between 3.6 and the
3.7 beta 39.
3.6 seems to ignore the interior_texture and the texture object modifiers if
the texture_list is specified within the body of the mesh2 definition,
whereas 3.7 beta 39 works as I described in my last posting.

I guess the thing is quite simple: The generic "texture" and "interior_texture"
are fallback textures that are applied to all triangles that don't have a
texture_list item assigned. So if you do assign a texture_list item, that
texture is applied to both sides, and both "texture" and "interior_texture"
remain without effect to this triangle.

It's a pity there is nothing like a "interior_texture_list", but I guess we have
to live with this limitation for now.

What you could do would be to split up the mesh object by textures before
exporting to POV-Ray, strip each of the resulting objects of the texture_list,
and assign both a texture and interior_texture. Finally combine them via a
union.

I thought no problem, download and install 3.7 and it works. But... on 
www.povray.org there is only a 3.7 beta 29 (64 bit) with an expire date 
of the 1st of November 2008. I tried but that one refused to do his job. 
   Where to get the 3.7 beta 39?

Thanks and greetings...
Wijnand

For the beta 39 you may still have to wait a while I guess :) But Chris promised
to rush out the beta 30 (basically a not-so-strictly-deadlined beta 29 if I
understand him correctly) in a few hours, and a beta 31 with functional
improvements in what I take to be a couple of days.

Hi Wijnand,
	On the Beta page there is a 32 bit version as well.
http://www.povray.org/beta/

http://www.povray.org/beta/POV-Ray%20for%20Windows%20v3.7%20beta%2029.msi

There is a workaround to disable the expiry date but an updated version should
be available very soon.

See the post by "Random Coder" on this thread.

http://news.povray.org/povray.beta-test/thread/%3Cweb.495c49605fe797ab30acaf600%40news.povray.org%3E/

You may have to fix the broken lines due to word wrap ;)

No no.. not back to the 32 bit version, I bought XP Professional x64 
edition for speed and not because I like to throw away money. I read 
(...) the post by Random Coder and wait patiently you have promised to 
Clipka.

Thanks...

Hello Chris,

I assume you meant Chris Cason, but he did indeed do that; See 
http://www.povray.org/beta/
It says it expires 1st of February 2009, but I don't know if that's a strict 
deadline.

Regards,
Chris B.
