Game editor creates a special file (log file) with various messages that may be useful for debugging.
Log file is saved to:
Normally only the most important events are logged.
If you have trouble identifying an issue, you might want to change log to verbose. This way more information is included in logs.
- Unity: select Tools → Charon → Troubleshooting → Verbose Logs..
- Standalone: Launch the application with additional parameter --verbose.
Then repeat the action that causes the bug (or the one you want analyzed anyway) and check log file again.
