Random UV Map Material

Description:

Sometimes we need apply different UV Maps on the same object, like a Light on Christmas Tree or a sofa fabric pattern, so I made this material, that have a random UVMaps, a simple way to made a example of use is with this letters.

1º Column= The UVMaps is mix with variants, it is good for fabric and other things that don't have a same patern.

2º Column= The UVMaps are change between some options, there are 4 UVmaps and that material pick one of that’s 4 and apply on each object.

3º Column = Array modifier problem, the material don't work, someone can help?

4º Column = Array modifier problem, the same problem with the 3º column, the material don't change.

I made this material to try to solve this problem
