Error: Could not find any nodes

Hey everyone, I am posting here in hopes for some help. I modeled a table in Maya, exported it into 3D Coat just fine, and then when exporting from 3D Coat into Unreal, only my textures went through and I received an error stating that the import had failed due to the fact Unreal “Could not find any nodes”. And so I went into Maya, and tried exporting the selection into Unreal that way, and I was met with the same error. So I went to an earlier save file, before any exporting into 3D Coat, and was STILL met with this error. I am losing my mind over this, and can’t figure it out at all. What is a node? How do I fix this issue?
