UE5.3 Eye occlusion Metahuman black artifacts

Hi everyone i know that there are already some post about it, but i didn’t find any valid solutions. For example for me didn’t resolve changing the shader from traslucent to additive, because yes, the artfacts goes away, but the eye occlusion doesn’t work anymore, the occlusion doesn’t work. I missing something? Can someone tell me if i need to do something else other than changing the type of the shader? Is there another solution? Thank you
