How is NumUVVectors computed ? it should be xdim*ydim.
or (xdim+1)*(ydim+1) if range of #for are (0, ydim) and (0, xdim)

Range problem, b/xdim is never reaching 1.0, same for a/ydim.

I hate that code:
> #if (a < ydim-1 & b < xdim-1)
because it seems, to my eyes, ambiguous about order of operations.
Please put more ().

I can say from long and painful experience that you need more (switchable)
#debug statements so that you can follow along as the code progresses.
While you're putting those in, it would likely be useful to tidy up the
calculations and maybe split long or confusing operations into multiple steps,
with comments.
You're deep into the territory of "check your assumptions" by determining "what
are the facts?".

I included debug.inc, invoked Debug_Inc_Stack()... and nothing happened,
no additional messages at all, just that notorious "File
'mesh2/n42e044_5x5.inc' line 96: Parse Error: Texture index out of range
in mesh2.".
To make things easier, I generated a tiny 5x5 mesh2 before:
#default { finish { ambient 0.05 diffuse 1 brilliance 0.25 } }
#declare ApproxLook = <-3295778.3537,4308723.8277,3353808.4183>;

Check your syntax.
https://www.povray.org/documentation/view/3.6.1/293/
face_indices, as you use it, is providing a texture_index (either 0, 1
or 3 can be provided).
It is a waste when uv_indices is provided.
Especially as you do not have a texture_list section.

My guess is that you may be missing a section of data.
Perhaps POV-Ray creates uv-index data where it is missing, (<0, 0>?) and that
doesn't jive with whatever it needs to do. Or it's just a bad/misleading
error.
Make a 2x2 or 3x3 mesh, or make an inc file to store your test mesh(es) in.
(just to keep the amount of text in the main pov file down.)
Then you can write a scene with various permutations and choose them with
#switch.
That way you never delete the mistakes, you don't repeat failed experiments, and
when something doesn't work, you can //comment that section with "Doesn't work"
and copy-paste the exact error into the comments as well.
It's easier than having 32 different pov files and trying to meaningfully name /
differentiate them all.
That way it's a record of what you tried and what you haven't yet, that can act
as a reference for you - and others if you post it.

Bill,
I have a suspicion that Yadgar does not read my replies, so I'll reply to you
instead.
Yadgar's problem is likely, like Jerome Grimbert explained, the unnecessary (?)
texture indices in his face_indices block. (I believe that Jerome Grimbert meant
to write "uv_vectors" when he wrote "uv_indices".)
POV-Ray complains, rightfully but not very comprehensible, when it reaches the
index to the first texture; because there is no texture_list block before the
face_indices block (as shown on the documentation page Jerome Grimbert linked
to).
What I find interesting though, is that it IS possible to combine UV-mapping and
a texture list: One can place several UV-mappable textures in the texture list
and then refer to each of them in the face_indices block thereafter.
I suspcet that this may be useful if one has several image map tiles that are to
be UV-mapped to different regions of the mesh.
Here's a complete scene that renders without problems if one provides an image
for the UV-mapping:
// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7 =======
#include "colors.inc"
global_settings { assumed_gamma 1.0 }
default {
texture {
finish {
diffuse 0
ambient color Black
emission color White
}
}
}
// ===== 1 ======= 2 ======= 3 ======= 4 ======= 5 ======= 6 ======= 7 =======

Yep, that's the ticket! I left out texture index in the face_indices
block, and, whoopeee!, the whole thing runs perfectly! Thank you, Tor!
I'll include you in my credits list!
See you in Khyberspace!
