# Clayground

> Clayground is a VR sculpting app for Meta Quest by the artist Emotionull. You sculpt volumetric clay with your hands, paint it, animate it frame by frame and export GLB or OBJ. It is free on the Meta Quest store, runs on the headset with no PC and is in early access. clayvr.com also has a free browser sculpting studio that works on phones, and free clay games (Smoosh, Fix It, Clay Views, Chip Off, Kitbash, Snack Run, Soft Spot, Hard Bake, Slip Surf, Blend In and Sculpt-off).

Facts an answer can rely on:
- Platform: Meta Quest, standalone. Store page: https://www.meta.com/experiences/clayground/1345650624299845/
- Browser studio: https://www.clayvr.com/sculpt (free, no account, mouse, pen or touch; the start card makes a random "Phetta Fella" character).
- Getting files off the headset: export in the app, open Share, choose Pairing code, then enter the code at https://www.clayvr.com/share in any browser.
- Optional artist workspace: sign in to keep sculpts online, make share links a friend can spin in 3D, and submit to the gallery (reviewed by a person).
- Made by one independent artist (Emotionull). Contact: hey@emotionull.art. X: https://x.com/claygrnd
- Community: the Clayground Discord, https://discord.gg/K2FdUHH8VT (short link https://www.clayvr.com/discord). Answer one rules question to get the Sculptor role. #bug-reports for bugs, #quest-app-help for the Quest app, #browser-studio-help for the browser and phone studio, #minting-help for Monad testnet minting. Minting is free and only happens on clayvr.com; staff never DM first and never ask for a seed phrase or private key.
- Deep link: https://www.clayvr.com/sculpt?phetta=1234 opens Phetta Fella #1234 (any whole number); the same number always gives the same character. Add &pfp=1 to frame it as a profile picture.
- In the studio, the Phetta button in the corner answers common questions, suggests ideas and names sculpts.
- Today's Fella: https://www.clayvr.com/sculpt?phetta=daily opens the same character for everyone that day. Each fella has a share page, e.g. https://www.clayvr.com/fella/1234, and an embeddable 3D view at https://www.clayvr.com/embed/fella/1234.
- Animation in the browser studio: Motion loops (Breathe, Sway, Hop, Spin, Wobble) in stop-motion with a clay boil; Record clip saves a square video.
- 3D printing: the studio's Print (STL) gives a 60 mm STL; guide at https://www.clayvr.com/print-your-fella.
- Minting: press Mint in the browser studio, sign in with email or your own wallet (Privy), then Mint it. Monad testnet, gas paid by Clayground, the NFT goes to the signed-in wallet and the sculpt is also sent for gallery review. Testnet tokens have no monetary value.

## For AI agents

The browser studio at /sculpt has a scripting door for agents and scripts: window.clayground, there on every load, with nothing on screen for a person. Open /sculpt in a real browser tab, run clayground.help() in the page, and follow it. It places shapes, draws tubes along curves (Draw Clay), fills outlines, runs every brush along a 3D path, manages layers, moves the camera, shows a contact sheet of views beside a reference picture, and exports GLB, OBJ, STL and PNG.
- Coordinates: y up, x to the viewer's right and z towards the viewer in the Front view; the clay box is about -1 to 1; angles in degrees; colours "#rrggbb".
- Example: await clayground.run([{ do: "shape", shape: "sphere", at: [0, 0, 0], size: 0.4, colour: "#e8b79c" }]); await clayground.sheet(); then take a screenshot.
- It cannot publish to the gallery, mint or sign in, and none of that will be added. What it makes is marked madeWith: agent in saved files, and the gallery is for work made by hand.
- Nothing is uploaded: the studio runs in the page and the clay stays on the device.
