Procedural Material keeping LayerInfo

Hi, I’m struggling with this problem from 2 days. I’m trying to create a procedural material like as described here. But the only problem with this method is that i cannot assing a physical material to each texture.
So practically, i need to combine the default landscape material workflow (painting) with the procedural. And i don’t know ho to combine them.

Comeone, anyone?

Currently you can only assign physical material properties to landscape layers- not individual textures within a material.

I might be mistaken but I think I read this will be addressed down the road.

I know that you can assing physical materials to LayerInfos but i’m searching a way to combine both methods.
