I'm working on an addon for Blender 2.6 to export to a mesh format that stores UV coordinates per-vertex instead of per-face. So, for vertices that lie across texture seams, I guess I need to duplicate them and have one for each side. My question is - is there a way to do this automatically in Blender? Just I've been trying to do it manually through the Python script, but it's more difficult than it seems to handle every possible case.
Thanks in advance.
