three.js Particles - Using three-nebula Particle Engine 

threejs examples itself, bruno simons course and if you want to get serious about it start studying computer graphics programming which comes with studying linear algebra and trig

Im in the process of trying to figure this out now, did you find a way to attach it to the Object. I'm try to add the effect to the back of a rocket i have orbiting. I tried to add it to make rocket mesh with rocket.add(nebula) but no luck

`import Nebula, { SpriteRenderer } from "three-nebula"; .... let nebula = null; let OBJ = new THREE.Group(); Nebula.fromJSONAsync(JSON, THREE).then(loaded => { const nebulaRenderer = new SpriteRenderer(OBJ, THREE); nebula = loaded.addRenderer(nebulaRenderer); }); OBJ.rotateY(Math.PI / 2); OBJ.scale.multiplyScalar(0.1); scene.add(OBJ); .... render(){ nebula.update(); } ` You can try this. It doesnt work for me because i have a Obj inside a Obj im trying to attach particleSystem 2

Dont run nebula.update(); In the animation function. Pass nebula and loaded through a function where you have your movments. In that function `loaded.emitters.forEach( emitter => { emitter.position.x = "model posistion" emitter.position.z = "model posistion" emitter.position.y = "model posistion" emitter.rotation.y = "model rotation" }); nebula.update();` Make sure to remove the quotes and add a real posistion and rotation.
