Description
Multiplayer Physical Backpack Inventory System is a fully physical, diegetic 3D inventory system for Unreal Engine that runs without a HUD, features full physics, realistic looting, and multiplayer support.
Key Features:
🎒 Real 3D Inventory — a real physical space
Instead of being bound to an invisible grid or slots, items lie freely in the container, interacting naturally with each other.
🧩 Gameplay Space Management
The size, shape, and mass of items matter:
the player must physically place items so they don't interfere with each other.
The inventory becomes a true minigame, not a list.
🧲 Stability System
Items don't fall through walls or fly off when walking.
🌐 Multiplayer-Ready
The system works in multiplayer out of the box:
Full physics synchronization between server and clients
Items move smoothly on both sides
The system has been tested under high ping conditions
💼 Isolation & Easy Integration
The asset is delivered as an isolated, pluggable Actor that can be embedded into any project with a character.
No professional skills required
Full documentation included
Several ready-made presets and examples
Clean, fully commented code
