Subject: How to do I create "real" interior textures (for logs, etc.)?

How do I create a log-like interior that works with CSG?
Create a cylinder with a log-like texture, make a CSG cut at 45 degrees with
intersection, receive a properly textured log.
- "texture" does not work for me - and it should not if I understand the
concept right.
- "interior_texture" should not work either, it should be only a texture
painted on the inside of a surface
- "media" has no texture (or am I wrong)
So how can it be done? A link would suffice.
Somebody is bound to have asked about this already, but I just can't find a
proper reference. So I posted here, where it should be least offensive.

If your cylinder already has a texture which looks good overall (ie. also
on the end caps of the cylinder), I don't see any reason why it would be any
different if you cut the cylinder with CSG. The texture would still be the
same and would work as if a log had been cut.
Of course you have to apply the log texture to the entire CSG object.
If what you mean is that you have a pre-declared log object and you want
to cut that, then add the 'cutaway_textures' keyword (see documentation).

"cutaway_textures " works like a charm!
Thank you! I completely missed this.

WRONG! OFF TOPIC POST IN THE OFF TOPIC BOARD!
Wait, is that possible? Let A be the set of all off topic posts...
But seriously, this is actually a really good question - I remember a variant
where someone wanted to do a cut-away view of a model of something mechanical (I
think a car transmission) with bright red edges where it was cut. Because the
model itself was a series of (sometimes nested) CSG parts, there was some
confusion about where to put the various texture{} blocks to get them in the
right place.
This is would be a good wiki article for Someone to write (possibly me?).
