Help with Model/Material/Normals jagged artefacting

I’m a new user when it comes to unreal and I’m bringing a creature into a scene to do some look development. I’m encountering this issue with weird artefacts on my model, only in unreal, other software is fine. I can’t seem to find any help related to this online so hopefully, someone here knows what I’m doing wrong.

I’m using UDIM for texturing, the issue doesn’t appear on all tiles.

Version: 4.25.3-13942748+++UE4+Release-4.25

Thanks
