Trying to get Parallax occlusion and detail material to work together

Hello all. Like the title says, I’m trying to apply a detail textures over a material with parallax occlusion, but I’m having trouble getting the detail textures to align with the displacement. When I add the detail textures node they float on the surface of the mesh, rather than following the displacement. Is there any way to fix this, or is this a limitation of the engine? I’d really appreciate any advice.
