Blender to Ue4 Texture César Salcedo's Eye Multiple Mesh Blueprint

I have made a character in blender and want to import it into ue4, i am able to apply the texture on the main mesh, as it is one piece and uv unwrapped. but both of the eyes are made up of 3 meshes each and a bit of nodes. i am a beginner and i am just learning unreal. i cant figure out how to replicate the effects created in blender. the eye is the eye from
