Before using this eye material, go to:

Edit → Project Settings → Engine → Rendering → Materials

Enable “Clear Coat Enable Second Normal”.

Restart Unreal Engine or allow the shaders to recompile if requested. This setting is required for the cornea and secondary normal details to display correctly.
