        var ss = ps.sizeBySpeed;
        ss.enabled = true;
	        ss.range = new Vector2(0.0f, 2.0f);

        AnimationCurve curve = new AnimationCurve();
	        curve.AddKey(0.0f, 0.1f);
	        curve.AddKey(0.75f, 1.0f);
	        ss.size = new ParticleSystem.MinMaxCurve(10.0f, curve);
    }
