Creating Paint Layers with MW Auto Material - help!

Hey, first of all I want to say that I know this topic has been brought up - but it never seems it has gotten an answer. And second, I am very new to UE5 so forgive my lack of knowledge.

My question is: How do I apply manual paint layers on my landscape using “MW Auto Material”? Do I need to manage the blueprint in someway, adding/adjusting maybe layer blend node or something else?

I am completely lost here, trying to find any answer on YT and forum here.

Let me know if I can provide with more information, thanks.
