Sync - Create Multiple Bodies, One Mind
Ever wanted to be in two places at once? Now you can.

What is Sync?
Sync enables you to create shells - physical clones of yourself with independent inventories, experience levels, and gamemodes. Transfer your consciousness between shells instantly across any dimension.
Originally created by iChun, this NeoForge port brings the beloved mod to modern Minecraft while preserving all its unique features.
✨ Features
- Multiple Bodies - Create and maintain several shells across your world
- Cross-Dimensional Travel - Instantly transfer between shells in different dimensions
- Death Insurance - When a shell dies, return to another shell instead of respawning
- Individual Stats - Each shell has its own inventory, XP, and gamemode
- Biometric Lock - Shells are tied to their creator
- Automation Support - Use hoppers for automatic shell equipment management
- Color Coding - Organize shells with dyes
- Energy System - Powered by adorable animals on treadmills (piggawatts!)
- Highly Configurable - Customize every aspect via config
🎮 Quick Start
1. Create a Shell Constructor
Craft a Shell Constructor and right-click it to provide a genetic sample.
⚠️ Warning: Default config costs 20 HP (40 HP in Hardcore). Use golden apples or totems!
2. Generate Energy
Place a Treadmill adjacent to the Shell Constructor and lure a pig or wolf onto it.

3. Build Shell Storage
Craft a Shell Storage, power it (redstone or energy), and walk inside when doors open.
4. Transfer Minds
Use the radial menu to select and transfer into your desired shell!

💡 Pro Tips
- Organization: Color-code Shell Storages with dye
- Monitoring: Use comparators to track construction progress
- Safety: Mine Shell blocks with Silk Touch only
- Automation: Connect hoppers to shells for inventory management
- Power: Shell Storages need constant power (configurable)
- Dimensions: Works with custom dimensions!
