UE5 Niagara FX - Changing Variables With Blueprints

This video goes over a very quick and easy way to expose and change variables of your Niagara FX Systems through blueprints. This way you can work with lower quality particles/fx in your viewport and swap them to higher resolutions or quantities at Play/Render time.   

This can be useful for working with scenes quickly that need to be rendered in high quality for virtual production, or cinematic or film making in Unreal.
