Visual Scripting & Detail Texturing

Hi guys, I’m still learning so expect some noob content that you probably already count as “easy”

I have a few textures for my material,

Material

HAIR:
-Bump
-Diffuse
-Norm
-Opac(ity?)

SKIRT:
-Bump
-Diffuse
-Norm
-Spec(ular?)

-Diffuse
-Norm
-Spec(ular?)

Sorry for the bad images, but I think they refer to what I have to work from. Each three is different materials.
I’ve tried to link the opacity right to the opacity on the Detail_Material blueprint node, and I linked the diffuse and normal maps to the same on the normal map. I did not find anything related to bump, so I linked that to roughness. The result… Looked decent from afar, but if you zoomed in, the face was so malformed and looked like parts of the skeleton were poking out of the skull… Just some blood added and it would be a real horrifying scene.

Any idea what I’m doing wrong?

EDIT [12:31pm]
I did look at this section right here: Adding Detail Textures to Unreal Engine Materials | Unreal Engine 5.1 Documentation, but I’m still a little puzzled how to use the textures on my materials.
