I believe it will be under the learn section of the marketplace, although I could be wrong, I’m pretty new to Unreal. In the mean time I’ve set up a gumroad account you can grab the materials from. You will need to install the substance plugin (the current version of the substance plugin from the marketplace doesn’t work with 4.11 although it should be updating shortly) then you can import the Substance Painter files directly into UE4. If you’re interested I also put the Designer files, and some old school tiling textures from the files for download too.
