public float maxParticleSize;

Description

Clamp the maximum particle size.

Particles can become very heavy on fillrate. Use this setting to make sure they don't use too much performance when up close to the viewer.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {

private ParticleSystem ps; private ParticleSystemRenderer psr; public float minSize = 0.0f; public float maxSize = 1.0f;

void Start() {

ps = GetComponent<ParticleSystem>(); psr = GetComponent<ParticleSystemRenderer>();

var main = ps.main; main.startSize = new ParticleSystem.MinMaxCurve(0.1f, 5.0f); }

void Update() { psr.minParticleSize = minSize; psr.maxParticleSize = maxSize; }

void OnGUI() { GUI.Label(new Rect(25, 40, 200, 30), "Minimum Screen Space Size"); GUI.Label(new Rect(25, 80, 200, 30), "Maximum Screen Space Size");

minSize = GUI.HorizontalSlider(new Rect(245, 45, 100, 30), minSize, 0.0f, 1.0f); maxSize = GUI.HorizontalSlider(new Rect(245, 85, 100, 30), maxSize, 0.0f, 1.0f); } }
