Landscape Material pack

Hey there,

Sorry to bother! So after a while i thought i found all the perfect textures but since i have the substance database i just found tons of better-fitting textures for my landscape. If i now change a landscape material and apply it compiles 12k shaders. Which takes quite long.

So as you can see, it’s quite big with a lot of textures. Does roughness really do something? And is there a way to change 1 material on it and not having to compile all layers again? I can’t really redo my painting since my world is getting big. So the question is, is there a way to lower my compiling times?
