How to export materials to Unreal Engine?

Hello, I have a problem, I have blender 2.82, and I’m trying to export to Unreal Engine a character I have in blender, now the thing is that when I import it into UE4, the materialss are the one displayed in the viewport, not the rendered materials, so the materials and textures aren’t being exported, I’m new to this and I need help, I’ve read and it seems i’ll have to do the material nodes again in unreal, but I don’t know what are the equivalents of each node in unreal… Isn’t there any addon or any workaround to export the materials?
