Applying a Colour LUT to Specific Objects

Did you ever figure this out. I’m trying to figure it out myself so I can create a ramp for the shading to create a cel shader with a softened edge.

Mihoyo seemed to use a LUT in Unity to create soft cel shading and I want to accomplish the same thing in unreal because I’m used to being able to use a color-ramp node in blender for cel shading.
