BlueprintCore – Blueprint Protection Plugin for Unreal Engine

BlueprintCore is a powerful Editor Extension for Unreal Engine that allows you to protect your Blueprint assets by making them read-only or entirely locked from modification. It’s designed for developers who want to share projects while maintaining control over sensitive Blueprint logic.

With BlueprintCore, you can disable editing of specific Blueprints for unauthorized users while still allowing them to create child Blueprints that inherit functionality. This ensures your core systems remain protected while staying extendable.

🔐 Key Use Cases

• Project Sharing with Restrictions: Share your project with collaborators while hiding Blueprint logic. They can still create child Blueprints and use exposed functions, but cannot see or edit the parent Blueprint's graph.

• Team Collaboration: Ideal for teams with separate roles (e.g., programmers and designers). Designers can view Blueprint nodes without being able to modify them.

• Secure Distribution: Distribute protected Blueprints using Key Files to ensure only authorized users can edit them.

🛠️ Features

• 🔒 Hide Blueprint Graphs (Nodes / Source Code)

• 🔑 Key File Protection: Lock Blueprints to specific Key Files. Without the correct Key, the Blueprint is locked and uneditable.

• 👁️ Read-Only Mode: Prevent editing while still allowing visibility of the Blueprint's contents.

• ✏️ Selective Locking:

  • Enable/Disable renaming of Blueprint Graphs & Events

  • Enable/Disable Variables

  • Enable/Disable Functions

  • Enable/Disable Macros

  • Enable/Disable Delegates

  • Enable/Disable Event Graphs
