Apply a shadow bias to prevent self-shadowing artifacts. The specified value is the proportion of the trail width at each segment.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { private ParticleSystem ps; public float hSliderValueBias = 1.0f;
void Start() { ps = GetComponent<ParticleSystem>();
var main = ps.main; main.startColor = new ParticleSystem.MinMaxGradient(Color.red, Color.yellow); main.startSize = 0.1f;
var trails = ps.trails; trails.enabled = true;
var psr = GetComponent<ParticleSystemRenderer>(); psr.trailMaterial = new Material(Shader.Find("Sprites/Default")); }
void Update() { var trails = ps.trails; trails.shadowBias = hSliderValueBias; }
void OnGUI() { GUI.Label(new Rect(25, 40, 100, 30), "Shadow Bias");
hSliderValueBias = GUI.HorizontalSlider(new Rect(55, 45, 100, 30), hSliderValueBias, 0.0f, 1.0f); } }
