Importing blender model

So, I’m remaking FNAF 4 in Unreal Engine 4 and i’m trying to import EverythingAnimation’s Nightmare animatronic models. But when i try to Import the FBX if i import as skeletal. it fails to import. and when i don’t do that. The model imports without a rig or the textures. What can i do.

Here are some images

Do you created the model, or is it a rip?

You exporting a skeleton of this model with two or more root bones, but UE support only rig with one root bone.
