Interact Sandbox 5.1+|Interact Sandbox 5.1+

 The Interact Sandbox 5.1+ game resource pack provides a feature-rich interactive sandbox that enables quick prototyping by offering networked multiplayer support for key systems. It includes an Interaction System, Inspection/Grab System, Inventory System, and Vehicle System—all designed with networked multiplayer capabilities. The package supports Unreal Engine 5 and is highly extendable, allowing developers to integrate custom actor types such as eggs, vehicles, or rockets. Players can freely grab, inspect, pick up, and interact with world objects while maintaining server-authority control to prevent unauthorized client-side modifications. The inventory system features a decoupled backend that operates via API principles, enabling full customization of the GUI—such as removing the default interface and replacing it with alternative widget designs. Designed from the ground up for multiplayer environments, the system ensures secure, consistent state management across all clients.
