[SOLVED] Need help with a model with more than one UV map

[Sir Teatei Moonlight]

I'm using 2.79b so it might be different for you but the general ideas should hold

1. have your mesh with 2 UV maps
   
2. duplicate the mesh twice
   
3. don't change mesh 0 (the original), keep it around
   
4. delete UV 2 from mesh 1, so it only has UV 1
   
5. delete UV 1 from mesh 2, so it only has UV 2
   
6. name them accordingly
   

it's not hard to generalize to any number of UV maps, just duplicate until you have one mesh per map and delete all but one on each (and keeping the original)
