So you used the same textures, but changed the shaders & textures?

no, its a “skinpack”. he making new textures and naming them the same as in the real maps, but packing it in a different pk3 of course not in pak0. in this method when loading the map which still the same, it still looks for the same named textures, but under the same name it founds a different looking one, coz effectively the new pk3s “overwriting” the original ones. ofc not really writing over the pak0, only effectively it looks so. game engine written that it will prefer external paks instead of pak0 this enables modding skinning et c… this is my guess.
