    {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var customData = ps.customData;
        customData.enabled = true;

        AnimationCurve curve = new AnimationCurve();
        curve.AddKey(0.0f, 0.0f);
        curve.AddKey(1.0f, 1.0f);

        customData.SetMode(ParticleSystemCustomData.Custom1, ParticleSystemCustomDataMode.Vector);
        customData.SetVectorComponentCount(ParticleSystemCustomData.Custom1, 1);
        customData.SetVector(ParticleSystemCustomData.Custom1, 0, new ParticleSystem.MinMaxCurve(1.0f, curve));
