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?

Nothing too extensive. I quickly ran it against about a dozen mesh2
files I had laying around from both poseray and 3dwin4. Largest was
132572 triangles. It worked fine. Give me a day. I investigated the
"transforms" tab and I see that its functions could have some
application for me too. I also remember that povtree also generates
some kind of mesh. So I can try that too. Maybe make a furry tree?
