New! Blueprint node to improve logging functionality of your scripts! Log into predefined categories and with selected verbosity levels.


This tool is based on experience I gained working for big game development studios, and shipping successful AAA titles.

Proper logging culture is a massive boost to your project and huge time saver.

This tool is my contribution to make debugging easier for everyone. It will streamline your bug fixing process and will make it less painful.


  • You can go through your saved logs and decrease the scope of research by using always available one-click category filter panel.
  • Color-coding support will make it easier for you to navigate through multiple log categories.
  • Make preferred configuration default, and preserve it between engine restarts.
  • Open previously saved log files and keep them on different tabs. You can even compare two different logs by placing tabs near each other.
  • UX matters a lot for me, so everything is accessible in one click.


Plugin is located under Window->Log->LogViewer


No more notepad, regexps or file editing.

Happy debugging!
