Add Downloaded Assets to a UE4 Project
Step 1 After purchasing the material package, click download to download the Zip file.
Note If you are not adding these materials to an existing project, you must first create a new project in Unreal Engine 4.

Step 2 Extract the contents of the downloaded zip files into the "Content" folder of your project.

Note A file with the same name as the downloaded file will now appear in the “Content” folder of your Unreal Engine 4 project.
To use the materials in a different project, repeat these steps, and extract the files into the Content folder of a different project.

Note Inside the downloaded folder will be three sub-folders named, “Maps” “Materials” and “Textures.”
Double-click “Overview” in the “Maps” folder to open a level where you can view all the materials.

Note The “Materials” folder contains three sub-folders.
-
Material instances in the “MaterialsHD” folder are designed for desktop applications
-
Material instances in the “MaterialsMobile” folder are designed for Mobile applications.
-
The “Parent Materials” folder contains the Material Blueprints for both Mobile and HD versions.
