Greetings all,

I'm trying to create a trophy with engraved lettering on it.  Simple
enough, right?  Create the trophy (done), create the script (done), and
make a CSG differencing the script from the trophy.  Except - I made the
trophy in another program and imported it into Moray...and Moray will
apparently not allow me to create a CSG from a UDO...

Of course, I could try to recreate the trophy in Moray, but I would like
to avoid that if possible...

Any suggestions welcome!  Thanks for your time.

Dan

  I would presume the udo is a representation of a mesh object. Mesh objects
are not allowed in any csg operation except for the union operation. You
will either have to reconstruct it using Pov primiatives or try differencing
your script from a flat box or something similar and attach it as a plaque
or some similar senario.

Ken is right here: UDOs themselves can be in CSGs, as long as all POV
objects that are used in the UDO can be CSGed. Otherwise, strange things
will happen :-)

I just thought of something- if you have a POV-Ray inc file, it could become
a UDO/INC file with absolutely no conversion, only a wireframe generation of
some sort. The holy grail looms closer...

Hmm, not to *this* caveman.  Could you explain in words of one syllable (or
less) what you're talking about?  I only became aware of Povray a couple of
months ago.  Picture the monkey scene at the beginning of Kubrick's "2001" and
you'll get a fair idea of my understanding of Povray...

it was rather unrelated to your original topic. In fact, Johannes's original
comments as to the unworkability of using triangle meshes in CSGs.

Actually Nathan Kopp's Patched Pov will allow you to use meshes is CSG's, I
think. As long as they are closed meshes. However I haven't used this features
so I don't know if what I'm saying really makes any sense.
