 So you want to bring a basic object from Blender to Unreal, not a problem. If you have a simple UV mapped textured object, the easiest way to get it to Unreal is by selecting it, file, export fbx, selected objects, under geometry you can apply modifiers if you have them, change smoothing from normals to face, and if you don't have a rig, turn off ad leaf bones, if you don't have an animation, then don't bake any. Export then in Unreal, control spacebar to bring up the content browser, import, find your object in all the related texture maps, import, if you get this message it means that you forgot to check smoothing to face instead of normals. Now to add textures to it, double click the object, then double click the material, and you will essentially find yourself in a shader node editor system almost identical to the one we have in Blender. So if you've ever seen my procedural texturing Blender series, I think it's like 20 minutes long, then you will have a very good idea how this editor works. I'll cover the material editor in Unreal later, but for now you just drag all your texture maps in, and plug them up the exact same way you would in the principle shader in Blender. Albedo goes to color, metallic goes here, your roughness goes here, the normal goes here, and the ambient occlusion goes here. You're done. Hit apply, and your object is now ready to be dragged into your game exactly the way it should be with all of the correct textures. Hope that helps, and as always, I hope you have a fantastic day, and I'll see you around.
