Object fade from view during animation

HI, I am new to UE4, and I’m working on an exploded view animation of a headrest, and I need the leather of the headrest to fade away before the mechanical components of the
headrest begin to un-assemble.

How can I accomplish this?


Make a material, add a sample of a noise/cloud texture into it.
multiply the RGB by a scalar.
use this result as the Alpha input on the Mask material pin.

At runtime, change the scalar to affect the transparency of the material.
