Hi,
I have a spline laid out in a level (3 splines in total) and inside the spline BP, I add a Niagara Particle System in each spline point. This NS has distance based sleep setting wherein if the distance is more than 8000 units, the NS goes to sleep. This is to keep performance optimal. I made the NS a child component of each spline point. During game play, while testing for performance, I notice that none of the NS are going to sleep. All NS are awake. While the particles/emitters themselves do not render due to distance based culling, the systems themselves do not go to sleep. Why is this happening? Please see below images for my set up.
