Help with Metahuman identity / metahuman creator in UE5.4

Hi guys,

Some help required here… I am trying to create a metahuman. I created the head from a website, and imported the obj into Unreal. Then I created a metahuman identity and solved for it. Everything went fine

I then did mesh to metahuman auto rig / full body. However when I download it, and apply the same textures… my Metahuman looks nothing like my model

Then I tried another way by changing the skeletal head on the Metahuman blueprint.

That gave me better results… however, when I zoom in… this happens.
Can’t figure out why or how to fix this…

some help would be appreciated
