hi, i just had a chance to try out uvlayout, and here are my first impressions. i've played with it ~6hrs

mind me noobness

positive
- interface is very friendly
- the learning curve is very good
- ease of use - very good
- the amount of stretching produced is very low
- i could boot the application and in no time start uv
mapping

negative
- webbing is essential, but the surrounding area should be forced not to overlap (in extreme cases there's still quite a bit of overlapping)
- when a vertex is pinned, the given vertex should not
be involved in any overlapping!

feature req
- a way to select edge loops in UV (and move them as a
group)
- an option to move pinned vertices as a group
- it'd be cool to select a face, pin, and all included
vertices would be pinned. would work well for larger
areas.

and to give another vote to things that are being
worked on:

- undo
- unwrap that will work on closed surfaces that are
cut up (head/cylinder)
- being able to work on just one half of a symmetric
model and at any time mirror

bugs
- i see RELAX even when in ERROR mode, it'd be cool if we coud toggle relax off
- i've had issues when i export the model, it is scaled way up, and is shifted in world space

this is what i payed with:

Many thanks for spending time to compose your feedback and pics!

Yes, I do need to work some more on the webbing ... already someones asked for a way to shape/stretch/shrink the webbing poly so its not strictly related to the 3D geometry. I've found that it can work better on mouths if they are open, so if you have a morph target/blend shape with mouth open, load that into UVLayout.

Agreed. UVLayout is currently lacking in the manual edit side of things; our focus has been to get the auto flattening as good as possible so less manual editing is required, but we do recognize that some better hand tweaking tools would be good to!

Yes, more a feature than a bug, requested by another user. I'll add a preference toggle somewhere so you can choose how you want it.

Hmmm, that does sound like a bug. You could try the "Update" export method; that just changes the UVs in the original imported OBJ, so vertex coords will remain untouched.
