So I have a Texture 1, Texture 2 and a alpha texture for blending the texture 1 with texture 2 with a Lerp.

I need to have 1 displacement map for texture 1 and another displacement map for texture 2, is this possible?
What I want achieve is: a material with micro detail (with displacement map) and a macro detail (with a different displacement map)
how to do this?

please don’ t ignore this noob question :wink:

Do you really need displacet for the detail map? I would strongly recomend using a normal map for the detailing and a displacement map for larger things.

If you REALLY need to use it just set up your lerp like normal and then make sure you clamp it before you hook it up to your material so you dont get values above 1 or below 0.

A standard multiply with a clamp could also work, you might get some artifacts from the clamping there im afraid.

Thanks for your answer,
I need this much detail and variation for showcase my 3d assets inside UE4 not for gameplay, something like Marmoset Toolbag 2 already do.

Thanks
