Blueprint Performance Inspector
Blueprint Performance Inspector is an editor-only analysis tool for Unreal Engine that helps you identify common Blueprint performance issues early, before they turn into runtime problems.
The plugin scans Blueprint assets and highlights patterns that are known to cause unnecessary CPU overhead, such as unused Tick, overly complex functions, heavy construction scripts, excessive references, and risky class defaults.
Instead of profiling at runtime, this tool performs static analysis on your Blueprints and presents the results in a clear, structured report with actionable suggestions.
