My problem may be (unnecesarily) complex as i tried alot of things mostly unsuccesfully. If you have any better solution than mine, please tell me !
I'm trying to make a collar for a character, my idea was to make only a part of it, then array/curve or shrinkwrap it around the character's neck, then finally bake it (unfortunately i have to bake it, my game doesnt accept too much polys and the collar is too complex)

So i did a basic model, ready to receive the array modifier Then made an basic armature of the body trying to make the collar fit

And tried various things from shrinkwrap with the armature, array or curve and it never came right.
Factually, maybe the bake doesn't need it, or maybe i could make it right on a plane? I don't know. Maybe you'll have the right answer too.
