Packaging failures in Unreal Engine are often caused by small, hidden issues—duplicate asset names, broken Blueprint logic, or missing project configurations. This tool performs a Deep Logic Scan to surface these issues instantly, saving your team hours of troubleshooting and preventing Friday night build-failures.
Key Benefits:
Reduced Package Failures: Identifies the most common causes of "Cook Failed" errors before they happen.
Performance & Size Optimization: Helps you find oversized textures and unused assets, leading to a smaller, faster final build.
Actionable Data: Export a timestamped CSV Report to keep a record of project health or delegate fixes to your team.
Deep Blueprint Audit: Detects compilation errors in assets that haven't been opened in months but would otherwise break your build.
Core Features:
Asset Collision Detection: Find duplicate asset names that cause silent naming collisions during cooking.
Blueprint Integrity Check: Validates that all Blueprints are clean and ready for deployment.
Configuration Guard: Ensures critical settings (like Game Default Map) are set correctly so your build doesn't launch to a black screen.
Texture Auditor: Surfaces large textures that might be bloating your final package size.
Native Integration: Fully integrated into the Unreal "Tools" menu with a clean, color-coded Slate UI.
