Blender MixPBR Node

This blender node makes your life easier if you want to mix or blend PBR texture sets via a mask input before actually plugging it into a shader node. The normal channel has two different outputs. The "Normal overlayed" channel correctly blends in the second normal map to the first. This is useful if you want to add more detail to the normals of the first PBR set. The "Normal masked" channel works as you expect a mask to choose from Normal 1 or Normal 2.

In the example images you see the node, and the example material in the blend file, showing the mask, material 1, material 2 and the mixed result with either masked normals or blended normals.

Created for Blender version 2.93.x (should also work with 2.8x+).
