public bool startSize3D;


A flag to enable specifying particle size individually for each axis.

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;

void Start() { ps = GetComponent<ParticleSystem>();

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; }

void OnGUI() { hSliderValueX = GUI.HorizontalSlider(new Rect(25, 45, 100, 30), hSliderValueX, 0.0F, 360.0F * Mathf.Deg2Rad); hSliderValueY = GUI.HorizontalSlider(new Rect(25, 75, 100, 30), hSliderValueY, 0.0F, 360.0F * Mathf.Deg2Rad); hSliderValueZ = GUI.HorizontalSlider(new Rect(25, 105, 100, 30), hSliderValueZ, 0.0F, 360.0F * Mathf.Deg2Rad); } }
