The Requirement Niagara is great for simulated particle systems, but its renderers seem pretty useful for non-simulated things as well. What if I just want to give Niagara a set of points, and tell it to use those as particles?
My use case was a “throwing arc” visualisation, for when you’re aiming a thrown projectile. UE provides you with helper functions to generate a list of points from a given start position and velocity (see the “Predict Projectile Path” suite of functions), and I want to display that in the world to preview where I’m throwing it.
