Material is just a solid color

So I just designed this in blender, and brought it into Unreal. When I apply a material to the bed frame, it applies fine, but with the door frame, it’s just a color.

did you unwrap the UVs properly? if the uv is too small or large in scale then the material wont look right. try going into blender and unwrapping to the proper scale. it helps to bring the texture into blender so you can visualize how it will look before exporting it.
