Not that it matters much, but you could ask your questions in the STC thread itself. That way others might get the answer they're looking for if they're also wondering about something
And yes, as Doylle said, every 2 weeks I provide you with a model, already unwrapped. There seems to have been an error in the export of this mesh, as stated earlier in the STC competition.
Simply, the model decided to divide itself when it got exported, so if you're participating, you might want to select all vertices and hit weld. Or else you'll get some hard edges in places where you don't want em
Cheers!
