TerraLoop Border is a lightweight NeoForge mod that lets you configure vanilla world borders using chunk-based sizes during world creation.

Instead of setting a world border later with commands, TerraLoop Border adds a clean option directly to the Create New World flow. Each world can define its own border size before it starts.

Features

• Configure the border during world creation
• Set world size in chunks
• Minimum size: 1 chunk
• 1 chunk = 16 x 16 blocks
• Chunk-aligned border placement
• Uses the vanilla world border system
• Optional hidden border visuals
• Lightweight and focused

How it works

When creating a new world, open the TerraLoop Border options and choose the desired world size in chunks.

Examples:

• 1 chunk = 16 x 16 blocks
• 2 chunks = 32 x 32 blocks
• 4 chunks = 64 x 64 blocks
• 8 chunks = 128 x 128 blocks
• 16 chunks = 256 x 256 blocks

The selected settings are saved per world and applied automatically when the world starts.

Current scope

TerraLoop Border only manages the vanilla world border.
