RGB Texture Sample into Layer Blend

Hi everyone.

I’m a Unreal Engine beginner and learning how the tools of UE5 work. Right now I’m trying to create a material for my landscape and need multiple layers. Saw a tutorial where you can do that with “Layer Blend”. But how does it work if I need 3 Textures for one layer? Is there a way to combine them or do I have to try a different approach?

Picture attached of my problem.

Can you try this?


(When you click on M_Ground in the material editor you can select MaterialAttributes on the left)
