I currently have a wall made up of brick, rigid insulation, airspace, cast-in-place concrete, rigid insulation, gwb. The interior side is the gwb, and rigid insulation, those two materials are unlocked so i can stretch them below the metal roof deck exposing the precast core as the parapet wall. When i do this the surface material of the cast-in-place parapet wall shows as masonry brick, but the surface material of the cast-in-place concrete is set to none. If I change the surface pattern of masonry brick it changes universally and changes the cast-in-place, but if i change the surface pattern of the concrete cast-in-place nothing changes.
