hello Kenney!
Just got All-in-1 asset pack 3.7.0 and when I'm trying to import furniture kit meshes into UE, They are missing textures.
I've tried browsing through the Textures inside fbx, obj, other formats but they are empty. 

Thank you!

Furniture Kit is an older package which didn't use textures yet, instead it uses multiple materials with colors. It will probably need a different approach when importing into Unreal Engine
