A temporary endeavor known as Persistent Overhaul involves the replacement of current textures with new ones. PO is only compatible with Persistent Kingdoms 3.0. PO is merely a texture pack with some existing changes; it is not a new module. Due to the fact that this is client-sided, only you will be able to view any modifications made to the module; only if other people use PO as well, you will see the same textures.
