I want to create a fireworks simulator using SceneKit, and I want to achieve a similar effect to this: https://www.youtube.com/watch?v=nlLow7DbKkY
As you can see, each firework particle has a trail effect, creating the "spokes".
The sample above was mainly done using Unity's sub emitters. I haven't been able to find out how to do this with SCNParticleSystem, I don't think sub emitters are available in SceneKit. Is there a similar tool in SCNParticleSystem to achieve this effect?
Thanks in advance.
