Flatter Signs: A Mode 13h Addon

A Fabric mod for Minecraft 1.20.1 that adds billboarding to signs when paired with the Mode 13h shaderpack.

Designed as an addon for Mode 13h: MS-DOSify!. Without the shaderpack you can still use the mod, but signs will render as a cross/hatch model (like vanilla grass/flowers), because Mode 13h is what actually converts those models into billboards.

🧾 Why This Exists

Mode 13h already billboards several objects for that crunchy DOS look — but signs are special: the moment you billboard them, the vanilla text rendering becomes useless (no “real” front face to draw on).

So Flatter Signs solves the readability problem by:

  • making signs one-sided (like pre-1.20 behavior, fitting the “no backside” billboard logic),
  • and printing the sign’s content in chat with a vanilla-style prefix: <Sign> Hello world!

Reading a sign prints the contents to chat

✨ Features

📌 Billboard-ready sign models

  • Standing signs are turned into a cross/hatch model so Mode 13h can billboard them.
  • All wood variants supported.
  • Works with signs and hanging signs.

💬 Chat reading (right click)

  • Right click a sign to print its text in chat with a <Sign> prefix.
  • Shift + right click to edit the sign (since normal right click is now “read”).

🎨 Vanilla mechanics preserved (and made visible)

These interactions affect both the sign itself and the chat output:

  • Dye a sign → the text printed in chat matches the dyed color.
  • Glow ink sac → sign glows in the dark.
  • Honeycomb (wax) → sign becomes non-editable (even with Shift+RMB) but still readable/printable.

🪵 Resourcepack-friendly by design

  • Signs use the item sign texture, so they stay compatible with any resource pack automatically.
  • Wall signs are procedurally generated from the item texture: if your pack keeps the general vanilla sign silhouette, it should “just work” with no extra assets (otherwise, check Configuration below).

⚠️ Known compromise

Wall Hanging Signs

Wall hanging signs are flat, not billboarded. Their shape makes true billboarding impractical, so this is the best balance between:

  • readability,
  • visual consistency,
  • and not breaking the model into something uncanny.

⚙️ Configuration

A simple .json config lets you enable/disable each feature independently (billboard model, chat printing, one-sided behavior, shift-to-edit logic, dye/glow/wax behavior, hanging sign support, etc.).

  • Location: config/flattersigns.json (generated after first launch)

  • Use case: keep only the bits you want if you’re not using Mode 13h.

  • Resource packs with non-vanilla sign silhouettes may need:

    • wall_sign_texture_crop_height (1..16) — visible pixel height taken from the item texture.
    • wall_sign_texture_crop_offset (0..16, clamped) — vertical offset into the item texture before cropping.

🧩 Compatibility

Platform Minecraft Works? Notes
Fabric 1.20.1 ✅ Native target
Forge 1.20.1 ✅ Via Sinytra Connector + Forgified Fabric API
Without Mode 13h shaderpack 1.20.1 ✅* No billboard effect; signs appear as cross/hatch models

✅ Quick usage cheat sheet

  • Read sign: Right click
  • Edit sign: Shift + right click
  • Dye / glow / wax: Same items, same behavior — now reflected in chat readability too
