ParticleSystem.SizeOverLifetimeModule.sizeMultiplier

Description

Size multiplier.

This method is more efficient than accessing the whole curve, if you only want to change the overall size multiplier.

		sizeOverLifetime.enabled = true;
		sizeOverLifetime.sizeMultiplier = 1.0f;

		var psr = GetComponent<ParticleSystemRenderer>();
		psr.material = new Material(Shader.Find("Sprites/Default"));	// this material renders a square billboard, making it easier to see the size
	}

		var main = ps.main;
		main.startLifetimeMultiplier = hSliderValue;

		hSliderValue = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValue, 1.0f, 5.0f);
