Hi! I'm also trying to skin my models for the first time. I figured out how to create the mapping (like you just showed). But that's where I get stuck.
I would like to export the mapping as an image file, so I can texture in photoshop.
But I only seem to be able to export the actual texture (wich is still black at this point). How can I export the actual mapping? (lines & dots)

THX in advance
