It's done the other way round : you move the vertices until they fit the
texture and then save the object with the new uv coordinates. You can do
this with the free version I think but I'm using the Pro version which has a
3D view among other helpful features.

Got it.
You have to use Select By:Vertex, drag selection rectangle around
vertices you want to
move and move it. For the object with many triangles it's very painful
process. Also
(at least in freeware version) there is no way to zoom in/out. That's
why if points are
very close to each other you cannot select the vertex you want. The only
way to do that
is to resize the map first in X then in Y.
It would be very useful feature in this program - fill rectangle area
automatically :)

Here is the result.
I used low polygon DXF export. Is it possible to use the same
map for high polygon object?

In fact that's why I bought the Pro version. There are several modes for
selecting vertices, a zoom feature and a 3D preview that can work on top of
a paint program, so that you can edit the map in the paint window of the
editing software and see the changes reflected in the 3D view of UVMapper.
In any case it's still hard and not very pleasant work, and the main
commercial uv editors are so expensive...

The map itself isn't changed so you'll have to uv-map the object again :(
That's a major limitation of this sort of exercise.
OTOH, once your model is mapped correctly, it's possible to change the
original model a little bit (at least without adding vertices), reexport it
and remap it quickly by reusing the uv vectors defined in the first run
since it's possible to save the uv vectors independently (and in any case
it's a text file).

It's too complicated for me :)
As far as I understand whenever you have UV coordinates for your
mesh you can also use any procedural texture instead of image map.
Christoph, do you have in your isoWood collection any
appropriate procedural wood texture for the boats? We can try to
map it as well.

Hmm, it's a good candidate for next freeware Java program :)

That could be interesting. The relative absence of free or even low cost 3D
painting programs is a mystery to me (there's uvmapper and a couple of other
shareware and then we're in the 1000$ land). One possibility is that it's
much more difficult to program than it seems due to some hard topological
math involved. I wish I could paint models and apply 2d textures in real
time on the 3d model like I'd do with a real-life object and then have the
uv map created magically but I've not even sure that it makes sense. The
free/shareware uv mappers I've seen all rely on wrapping and unwrapping
vertices, not on 3D painting per se.

Good, except that the texture repeats every so often from one end to
the other. This is not painfully obvious, so you may find that the
non-repeating solution isn't worth the effort.
