Building your plot

From an empty plot to a published gallery: the editor, ready-made pieces, your own models, NFTs, portals, the sign by your door, and the wallet signature that puts it all in the town.

Where you build

• Your plot editor, in the town: sign in with the wallet that holds the plot and press My space in the tool bar. It edits every cell of your plot, in place, among your neighbours.
• The free builder: one 16 m cell, no wallet, nothing published. Good for practice; export a ZIP and import it later.
• On your computer, with an AI agent: your whole plot as a folder, built with Claude Code, Codex, Cursor or VS Code, then deployed with your wallet. See For AI agents and the SDK.

Your draft is saved on this device (this browser) as you work. Clearing site data or switching browsers loses an unpublished draft: export a copy from Share to keep it.

Start from a template

An empty cell offers whole scenes that stand there built at once, ready to walk and to hang art in: Gallery room with a garden, Studio with a terrace, Small plaza with a fountain, Pavilion, or Empty plot. Each piece arrives as its own group, so you can move or turn it afterwards; Undo takes the whole scene away in one step. Empty frames already hang on the inside walls.

Prefabs

The Prefabs shelf has old-town pieces in six families: starter buildings (small studio, three-bay loggia, gallery room), walls (plain, with a doorway, with windows, garden wall, cornice), floors and stairs (slabs, paved square, straight and turning stairs), columns and arches (column, arcade bay, portico, pergola), tiled roofs, and furniture and garden (balustrade, bench, cypress, lemon tree, lamp post, fountain, well, market stall). Prefabs are built from the editor's own shapes, plus a few shared roof models, and are sized for a visitor to walk through.

Shapes, moving and snapping

• Add blocks, spheres, columns and frames, then move, turn and scale them with the handles or type exact numbers. Units are metres.
• Snap draws a dragged piece to the ones already standing: wall end to wall end, corners on the prefabs' 4 m grid, a roof centred over its walls, fronts flush in one line, and whole storeys (3.5 m) when lifted.
• Solid objects (“Block walking through this object”) stop visitors and can be stood on. A visitor is 0.6 m wide and 1.72 m tall and climbs ledges up to 0.28 m: make doors at least 0.8 × 1.82 m and stair risers at most 0.28 m (prefabs use 0.18 m).
• Test walk lets you walk your plot as a visitor before you publish.
• Town scenery, terrain and trees start locked; only you can unlock something on purpose.

Your own models and images

Assets imports a .glb (binary glTF with embedded textures) or an image. The builder prepares a model on your device on the way in: it reduces heavy geometry, resizes textures, builds a lighter copy for distance and works out collision surfaces, then keeps the result on this device. A model it still cannot fit is held back with a reason. Before you import, read the limits and try Check my model.

Only upload models and images you made or have the right to show. Publishing makes them downloadable by every visitor's browser.

NFTs: token references, not files

• Hang works from My NFT library (your wallet's tokens) onto frames: drag, or select a frame and choose a work. The plot records the token (contract and id), not a copy of the file.
• NFTs do not count in your plot's weight or files. Visitors see them the way the Palazzo shows its exhibitions: a light thumbnail from far away, the display image up close, the original only when someone opens the work.
• At publish, your device makes small display copies of heavy works (GIFs, videos, 3D), signed with your plot: a still, a thumbnail and a short H.264 loop, or a lighter 3D copy. They have their own quota (15 MB a cell, up to 60 MB) and never count in your weight. See limits.
• Up to 24 live NFT displays per cell.
• The plot shows the token's current public metadata, read from objkt and TzKT. If the artist or contract changes it, your wall changes too.

Hanging a token shows it; it does not prove you made it or own its rights. Show only work you have the right to exhibit (house rules).

Portals

+ Portal places a stone arch with the destination's name. A portal can lead to a place in the town, another artist's plot, a published gallery world, a creator's space, or a website. Walk through it, click, tap or press E: a short veil offers Stay here or Go now.

• Up to 16 portals per cell (8 per gallery world).
• A website portal must be a plain https:// address: no user name or password, no port, no IP address, no localhost. It always asks first: “You are leaving Third Life for …”, and opens in a new tab.

Your gallery sign

Every published plot has a painted sign by its door. Write it under Share › Gallery sign: a name (up to 40 characters), a tagline (80), and links to your objkt profile, X and website (https only, 200 characters each). It is saved at once, without a signature. Visitors who click it see your links and how many works are for sale in your gallery. Links pass through the same “You are leaving” warning as portals. The host can hide a sign that breaks the house rules.

Publishing

1. Share › Publish your whole plot. The weight meter shows what the plot will publish: “12.7 MB of 25 MB · 2 of 200 files · 6 NFTs shown optimized, not counted”. It turns amber at 85 % and red when over, and names the heaviest files.
2. Prepare publication resizes your own large images (2,048 px, WebP), turns NFT frames into token references, makes the display copies and checks every cell.
3. Approve in your wallet. This is a signature, not a payment: no tez is spent. The site checks the signed plot again when it arrives.
4. Your plot is live. Each publish replaces the previous version.

If anything is over a limit, publishing is blocked until the plot fits, and the panel says what to remove. Nothing is uploaded until your wallet signs.

The gazette

The weekly town gazette is made from what the site already records: new and updated galleries, plots claimed or gifted, the busiest moment of the week, an event and an artist of the week chosen by the host. Publishing your plot is how you get in it. It also hangs on a board on the arrival square.

Live screens

The owner of a plot can show a live stream or a video on a screen at the plot's gate. The video plays in YouTube's or Twitch's own player and comes from them, so it costs nothing to show.

1. Open More › Live screens › Set up your live screen.
2. Paste a link: a YouTube video or live (watch, live, shorts or youtu.be), a YouTube channel's /live, or a Twitch channel or video. A link to a YouTube handle (@name) cannot be played: use the stream's own link (Share › Copy link). Kick and X links show on the screen as a link to watch there.
3. Add a title, pick the screen (at the gate, 2.4 m or 4 m wide, or 5.2 m high over the gate), an optional start and end time, and switch it on.

Visitors see the stream's picture on the screen with LIVE. Walking up to it, within about 25 m, facing it and with nothing in between, the player appears on the screen; the first one in a visit needs a tap (Tap to watch), and its sound fades with distance. Turning away pauses it; walking off removes it, so nothing downloads in the background. On a phone or tablet, a tap opens the player in a sheet. Screens on now are listed in Map and More › Live screens, and scheduled ones in the gazette's Coming Up.

The house rules apply. You are responsible for what your screen shows and for having the right to show it. Visitors can report a screen; the host can switch it off.
