Thanks for the script!
I’m just having some problems, which are causing me grief with a simple box model. I’ve marked seams where they should work, (after make-unfoldable) but then every time I re export they seem to get added to/ignored. I should be able to get a nice one piece map (like the UV unwrap below from the seams), but haven’t had any luck so far.
Any thoughts?

One of the varied results I get from the script, even after marking seams as above.
