  Then there's a serious bug in the program. I am able to read mesh2 (with
uv-mapping and textures) ok.
  Please make a proper bug report.

Now I'm confused.

On the interface the selections for input include:

1. POV-Ray file with triangle meshes
2. POV-Ray file with cubic patches
3. PCM file

The selections for output include:

1. PCM file
2. POV-Ray file
3. UV-Pov mesh2

I did try selection #1 with "Ignore keywork mesh" checked
but got:
"no objects found"

Forgive me, I don't know how to do that

Okay, a bit cryptic but I think I gotcha.

To be able to read it,
it matters which utility generates the mesh/mesh2.

Here is what I was able to test:

Can the mesh be read?

If generated by PoseRay v.0.1
Mesh - No
Mesh2 - No

If generated by CrossRoads v1
Mesh - Yes
Mesh2 - N/A

If generated by Win3D v4.3
Mesh - N/A
Mesh2 - No

If generated by MeshComp v3
Mesh - Yes
Mesh2 - Yes

If generated by POV-Ray v3.5
Mesh - Yes
Mesh2 - N/A


Not sure if it is a bug, but it means to me that
the only way I can get from a commercial format, such
as .obj, to PCM is via generating plain mesh in CrossRoads.

  Can you post a small example of those which the compressor can't read?

  This is exactly what I was looking for when I made the beta release.
There indeed is a bug in the program, and a rather simple one (or perhaps
more precisely a memory lapse): I forgot to make the parser to take
comments into account.
  For instance "mesh2 // comment" causes it to choke because it doesn't
skip the comment.
  I'll have to fix that.

I fixed the problem with comments. Please test it.

Have you tried with the beta2 version of the program yet?
