Hey Baolong -

You should be able to use a Texture Sample as a control map for a LERP between the colors you want to use. Or you can use one texture as a Subsurface color and one that acts as a controlling LERP alpha. If you can post a screenshot of your current setup and a brief description of exact how you think it should work, I can help you further.

Thank You

Hey Baolong -

If you look at the information found here, Subsurface Profile Shading Model in Unreal Engine | Unreal Engine Documentation, you will want to plug in your mask into the opacity channel as it “used to mask the subsurface scattering contribution (A value in the range between 0 to 1 allows smooth transitions, at the moment this does not scale the scattering radius/distance). 0 disabled subsurface scattering, 1 show the full extent.”

Thank You
