Unreal Engine 5 Documentation has been moved to the Epic Developer Community

Unreal Engine provides several different tools you can use to help debug what's going on in your simulations. The Debug Drawing tool enables you to see a visual representation of certain modules in your Niagara system while you're working in the Niagara Editor . You can use this tool while initially setting up your Niagara systems.

If you need to further debug Niagara simulations after they've been added to your level, then you can use the Niagara Debugger . This lets you turn on a heads-up display (HUD) that outputs detailed information about the simulations in your level, such as the number of particles being generated, the amount of memory being used, and more. You can also capture a snapshot of information and then analyze that output.
