You can setup the materials as an asset library using Blender's asset browser feature.

Open Blender's user preferences, and go to, file path, then, Asset Library's. Click on the plus icon, and then choose the folder where your storing the asset library Blender file. Make sure to save the user preferences. Then you can open Blender's asset browser window and access the materials.

If you don't know how to setup and use the asset browser, you can watch my setup guide tutorial video Here.

These materials were designed for Cycles, but they will also work in Eevee. Material displacements are now supported in Blender version 4.2, so if you're using version 4.2 or a later version, the materials with displacements will work in Eevee!

Blender Version:

Its recommended to always use the latest stable Blender version, because some of the procedural shader nodes were updated in the new Blender updates, causing some of the materials to not work properly in older Blender versions. I will always keep the materials updated to work in the latest Blender version.
