World Editor Overview

🌍 World Editor: Overview

🛠️ Part of the World Editor guide.

The Overview tab holds the world's own details: its name, its library card, and the text the AI reads on every turn. It has two columns. On mobile, the left column shows first.

The left column: how your world is listed

Field	What it does
World Name	The title on the library card and in every menu.
Author	Your name on the card.
Tags	The words the community browser filters on.
Thumbnail	The card's picture. Generate with AI under the frame makes one from your description.
3D Player Avatar	Gives this world a 3D avatar. The player can customize it before they start.
Custom Player Avatar	Advanced mode only, and only with 3D Player Avatar on. Your own .vrm or .glb replaces the bundled model. Preview opens it, and Remove goes back to the default.
Allowed Personas	Advanced mode only. Decides which personas the player can pick: Any or World Only. See Personas for Authors.
Starts On	Advanced mode only. Decides which persona a new player starts on. See Personas for Authors.
Background Music	The track the world plays. Drop a file on the box, or click the box to pick one.

The right column: what you write

Field	What it does
Player-Facing Description	The text on the library card and the community listing. Players read it before they play, so placeholders stay as plain text here. The AI never reads it.
Readme	Two tabs. Introduction shows before the player makes any setup choices. Gameplay shows when they enter the world. Both take markdown.
AI-Facing Description	The world's description for the AI. The AI reads it on every turn. Players never see it.
Custom Prompts	Advanced mode only. Replaces the player's own narration, choices or stats prompt. Its Openings item holds the world's Openings.

Upload or link

Every image field in the World Editor takes an uploaded file or a web address. Paste the address into the Or paste an image URL box.

	Uploaded	Linked
Stored in your world	Yes. The full size counts toward the file.	No. Only the address is stored.
Works offline	Always	After you've seen it once, or after Make Available Offline
Works after the host removes it	Always	No

• Link when your world has many pictures. A published world stays small.
• Upload when the picture must never disappear.

A linked image shows a 🔗 badge. Two badges are warnings:

Badge	Means	What to do
Expiring link	Discord attachment links stop working after a while. Later players won't see the picture. Discord's permanent addresses (avatars, emojis, server icons) are fine.	Use a permanent host, or upload the file
Linked image, display only	The site won't let Formamorph download the picture. It shows online. It won't work offline, and it can't go into a character card.	Upload the file

💡 Make Available Offline in a world's details window downloads all its linked pictures at once. Use it before you lose your connection.

When you export a world with linked pictures, you choose: keep the links for a small file, or download the pictures into the file so it works anywhere. A character card export always downloads the portrait, because the card is the picture.
