Value map driven color gradient?

Hey all,

I'm not entirely sure how to describe what I am looking to do in Unreal, But basically I followed along with Abe Leal's newest video on the Adobe Substance 3D Youtube channel where he textures a shark characters but he uses a technique where he creates a value map first and then uses a color gradient that uses the value map to put color on certain values. I want to take a value map that I create in Substance Painter, Bring it into Unreal, And set up a material that can use the value map to plot where each color would go. I want to do it this way because it can give me flexibility with which colors I want to use as oppose to using a color texture that I export out of Substance Painter.

Is there something in Unreal that can do this?
Thanks!

Here is the video I am referencing: https://youtu.be/8biEy1D30Bc?si=ZxqB-JPAiZp1Mmvm
The section after him baking his model is where he creates a values map

    yes - its simple to implement 

    eg. index into a lookup-texture using the valuemap   . eg.    color = texture2d(value, vec2(value, 0.0)) 

    in unreal you can also use a curve atlas in place of a manually created lut texture .  you can stack and swap these easily from blueprint so could be very useful.
