You can easily create material function with such functionality.
I’m new to UE4, moved from Unity. And I can’t find a regular Remap node in the material editor? Sure I can just create a couple of nodes for remapping values, but this surprised me, that this node is missing, or I just can’t see it.
This is the example of this node - Unity Products:Amplify Shader Editor/Remap - Amplify Creations Wiki
There is a remap node. It is called RemapValueRange under math section in 4.22. I am not sure if this node exists in 4.20
