Random texture offset in realtime

basically i am recreating a material from a unity game to ue4 and i got most of it down except one of the textures “shake”, (idk how to explain it) i just wanna know if someone knows how to get this effect cuz it would be helpful

Hard to say without seeing the effect itself. There are numerous ways to randomly offset a texture, either in a blueprint/code or in the material itself. If you could show how it works in Unity, that would be great.
