Track set dress across a production
Set dress belongs to the set, not to a character — one lamp, one photo set, hung on every set that uses it, and it stays there when a scene moves.
Set dress is the part of the warehouse nobody argues about until the day it is missing. Lamps, rugs, pictures, curtains, the radio on the sideboard — the things that make a room look like somebody lives in it. They are not props, because nobody picks them up and acts with them, and that distinction is the one the whole department runs on.
SceneMatch keeps set dress in the warehouse alongside props, vehicles, animals and wardrobe, and hangs it on sets.
Why it hangs on a set, not a character
Every other warehouse type ends up attached to a person or a moment. A prop is handled by a character. A costume belongs to a look. Set dress belongs to a place — the standing lamp lives in Elizabeth's flat whether or not she is in the scene, and it is still there three episodes later.
That is why set dress is attached from the set rather than from the character or the scene. Open a set, attach the pieces that dress it, and the list travels with the set wherever it is used. Move a scene to a different day, add a scene that plays in the same room, and nothing about the dressing changes — because it was never attached to the scene in the first place.
The practical effect: the load-in list for a set is built once, not rebuilt every time the schedule moves.
One piece, many sets
A set dress item lives at the level of the production, so the same piece can dress more than one set. A picture that hangs in the hallway of one location and the office of another is one entry with one set of photos, attached twice.
That matters for the same reason it matters in wardrobe: if you create a fresh entry per set, you end up with three "brass lamp" cards whose photos disagree, and nobody knows which one the dressing crew actually loaded.
Open a piece and you can see its photos and details; open a set and you see everything that dresses it. Both read from the same item.
The thing that is not obvious
Removing a piece from a set does not delete it. The item is production-level; the set only referenced it. Take the lamp out of one room and it is still in the warehouse, still attached to any other set that used it, photos intact.
The reverse is the one to be careful with: deleting the set dress item removes it from every set that used it. If a piece dresses three sets, deleting it is not a local decision.
Photograph everything
Set dress is the most photographed and least described part of the warehouse, and for good reason — "blue patterned rug" describes a hundred rugs, and a photograph describes one. Each piece has its own gallery on its item page.
Continuity for dressing is mostly a question of where exactly it sat. A wide shot of the dressed set plus a close photograph of the piece itself is the combination that answers that question weeks later, when the same room has to be rebuilt for a pickup.
Referencing it from the script
Set dress can be referenced from a screenplay annotation, the same way props and wardrobe can. Highlight the line that calls for it and attach the piece, and the reference shows on the script where the department reads it.
This is worth doing for anything the writer specifically named. A script that says she stares at the carriage clock has made the clock a story point, and a reference on that line is how the dressing crew learns it is not just any clock.
