using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public float hSliderValueX = 1.0F; public float hSliderValueY = 1.0F; public float hSliderValueZ = 1.0F;

var main = ps.main; main.startSize3D = true;

var psr = GetComponent<ParticleSystemRenderer>(); psr.renderMode = ParticleSystemRenderMode.Mesh; psr.mesh = Resources.GetBuiltinResource<Mesh>("Cube.fbx");// use a mesh, because billboards have no Z axis size psr.material = new Material(Shader.Find("Sprites/Default")); }

void Update() { var main = ps.main; main.startSizeXMultiplier = hSliderValueX; main.startSizeYMultiplier = hSliderValueY; main.startSizeZMultiplier = hSliderValueZ; }
