Modern Beta resource packs

Textures, models, and language files for the visual trickery that makes Modern Beta possible!

Each pack folder at the root level is discovered automatically. A folder is treated as a pack if it contains a java and/or bedrock subfolder. The same applies to packs inside _BasePacks and _OverlayPacks.

build-config.json

Place a build-config.json at the root of any pack folder to control how it is built. Config is split into java and bedrock sections so each platform can be configured independently. If a section is absent, defaults for that location are used.

{
    "java": {
        "basePacks": true,
        "overlayPacks": true,
        "includeCredits": true
    },
    "bedrock": {
        "basePacks": true,
        "overlayPacks": true,
        "includeCredits": true
    }
}

Field	Type	Description
basePacks	boolean	Merge files from _BasePacks into this pack before its own files.
overlayPacks	boolean	Merge files from _OverlayPacks into this pack on top of its own files.
includeCredits	boolean	Include CREDITS.txt in the output zip.

Root packs — defaults: all true

_BasePacks packs — defaults: overlayPacks: true, includeCredits: true

• basePacks is not applicable here — base packs cannot include other base packs.

_OverlayPacks packs — defaults: overlayPacks: false, includeCredits: true

• basePacks is not applicable here — overlay packs cannot include base packs.
• overlayPacks defaults to false — opt in via build-config.json when an overlay needs other overlays applied.

Merge order

1. Base pack files (if basePacks: true)
2. The pack's own files (always, overrides base)
3. Overlay pack files (if overlayPacks: true, overrides everything)

pack.mcmeta and pack.png are never copied from overlay packs — each pack keeps its own. Similarly for Bedrock, manifest.json and pack_icon.png are excluded.

Each Bedrock pack's manifest.json has its header.uuid replaced with a freshly generated UUID at build time.

Building

• Install Bun if you don't have it already.
• Open a terminal to the project root.
• On first use, install script dependencies: bun install --cwd scripts
• Run the build script: bun run ./scripts/build.ts
• Output is written to the out/ directory along with a checksums.txt (SHA1 hashes).
• To output directly to a different directory (e.g. your Minecraft resource packs folder), use --out:

  bun run ./scripts/build.ts --out "C:\Users\You\AppData\Roaming\.minecraft\resourcepacks"
