The majority of the meshes can be used as a pure mesh replacer, Some that are, are also in Mesh fix and eventually all that are will be included in Mesh Fix in due course. Most of the building meshes have had the UV maps adjusted specifically to accommodate the textures made for the overhaul So may look odd if you use textures that are in a different scale , There are a few meshes that use unique textures such as the bridge which has a cobblestone texture the greathall and 2 of the buildings which use dark plank textures which would cause problems if you used them as pure mesh replacers without their uniquely named textures accompanying them.
If it's not to much to ask, could u repackage those that goes well without the textures and send em to me?
