Two sided material or texture with emissive

Hi there I am megakyle83 and I have been learning to use Unreal Engine for the past year or so. My question: is there a way to use two sided (the material setting or texturing node) and have one side be emissive while the other side is not? I would really appreciate a screenshot as I am a visual learner. Also I can’t seem to find documentation on the TwoSidedTexturing node and I don’t know what all it’s functions are? Like mask, what does that one do? I am trying to rely less on texturing with images while learning to utilize the materials node system. Your help is definitely appreciated.
