Glad to hear that it's working out for you!
And don't worry for not understanding how the `sort_uvs_by_shells` function
works, it's my fault for writing it in a not so readable way.
I'll give a go at decomposing and describing each of its operations. It's a
good exercise for me as I'm usually pre
Thanks to both of you for your rapid responses! Using Christopher's
example I was able to get it working to where it could sort the uvs by
their shell (I must confess I don't exactly understand how the
sort_uvs_by_shells function works, but I'll study up on it and get it
figured out in my head).
