Metahuman Eyes Normal weird behaviour

Hello everybody,

Character not being my area of expertise, I’ve decided to dig a bit into Metahuman and make my own face! Long story short I went through the whole process of Mesh to MH and went above and beyond to implement a beard…
In Unreal I ended up with two BP of my MH basically: One with a beard and the other one imported directly from the Metahuman creator.

Now the problem I face is that I see some sort of weird normal behavior on my eyes when they are shut!
I’ve tried applying a flat NM in the texture to see If It was coming from the material but It doesn’t.
I’ve checked my MH in Maya and check if any weirdness was being displayed and nothing at all.
The base colour in the Engine looks just fine but the problem persists.

It’ll be great if someone has any ideas or faced it before so I can get some help.
You can see the screenshots below:

This is the original

And here is the error I’m encountering.

I hope this message will reach someone!
Thanks for the help
