Switch to Manual
public ParticleSystem.RotationBySpeedModule rotationBySpeed;


Script interface for the Particle System Rotation by Speed module.

Rotate particles based on their speed.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var rot = ps.rotationBySpeed; rot.enabled = true;

AnimationCurve curve = new AnimationCurve(); curve.AddKey(0.0f, 0.1f); curve.AddKey(0.75f, 0.6f);

AnimationCurve curve2 = new AnimationCurve(); curve2.AddKey(0.0f, 0.2f); curve2.AddKey(0.5f, 0.9f);

rot.z = new ParticleSystem.MinMaxCurve(2.0f, curve, curve2); } }
