Lerp node documentations says that:
A - Input is white.
B - Input is black.
However. I’ve been looking at ML_Metal_Dark from Blueprint Example, and playing with the roughness value. When I change A input it clearly respond to the darker part of the texture, (blacks) while changing B input responds to light part of texture (whites).
Is there something I’m missing or this is indeed an bug in documentation ?
edit:
Even screenshot on the same page shows that the inputs work in opposite.
