Material not showing after using displacement map

So I imported my Revit model into Twinmotion to add some elements and then transferred it to Unreal Engine for more realistic rendering. However, whenever I try to use a material that has a displacement map assigned it will only show up as the default square pattern. Is there a way to fix this? I had read somewhere about increasing the geometry of the static meshes but unfortunately I have no idea how this is done. Any help would be appreciated.
