The only difference(to the gumroad version) here is that all textures are 4K in the .blend files (except the 2nd prompt / secure, which is in Blender). You still do have to download Material Maker (free & open source) in order to inspect the nodes in the .ptex file or to export higher res textures.
I do have plans to finish a couple extra ones but I am bit busy around this time of year so they will mostly be done around mid-june or so.
