This is an add-on for the texture pack: Paper Cut-Out by SuperAlgae: http://niceminecraft.net/paper-cut-resource-pack/
You will need to have both this pack (w/ shader maps) and the original Paper Cut-Out pack (w/ textures) in Minecrafts resource list for it to work. Order of the packs doesn’t matter.
Sonic Ether’s Unbelievable Shaders: http://niceminecraft.net/sonic-ethers-unbelievable-shaders-mod/
