Unreal Material Simple gradient control

  1. simple linear gradient



Linear gradient function is taking texture coordinate, masking out U(R) and V(G)

U gradient is from left to right

V gradient is from right to left


Here I'm using a Switch parameter node to switch between u gradient or v gradient.


Then multiply to a scalar parameter for direction. When using U gradient, this would allow us to switch between left and right. When using a V gradient, this would allow us to switch between up and down.

Then Subtracting the gradient to a scalar parameter would allow us to do the dissolve effect.



To make the transition more interesting, subtract a noise texture.

Quick Demo
