Is it recommended to use NDC for continuous effects like trails or some environmental effects? It would be good to use because of it’s performance optimization. But we’ve noticed most of the demonstrated use cases are bursts of particles.
Steps to Reproduce
Hi, although NDCs are typically used for burst/event-driven particles, they can also be used with continuous particles. It depends on how your scene and systems are set up, as well as your visual goals.
NDC data is one frame transient -- meaning you need to either write to the NDC each frame, or cache the NDC data inside the Niagara System (and then use SpawnFromOtherEmitter to spawn your real particles). You can also pass in an ID if you want to stitch ribbons along each path.
If you give it a try, I’d recommend profiling your specific scene with and without an NDC setup for your continuous particles, to get a sense of the impact on both your workflow/setup and the performance.
I hope that helps!
