The pack requires OptiFine, which can be downloaded here.
Hey guys I made these models and textures like 2 years ago for a project I never got to finish and don't think I will be finishing, so I decided to release them as a resource pack that uses MCPatcher's custom item textures feature. I don't plan on updating or adding to this pack. Hope you enjoy.
To use the models in the pack you have to rename a sword or axe to a specific name. Those names are listed in the naming guide here.
