Change material of Particle System?

 var newMat : Material;
 
 function Start()
 {
     gameObject.GetComponent(ParticleSystemRenderer).material = newMat;
 }

in unityscript(javascript) you should use the generic version of GetComponent.

  var newMat : Material;
  
  function Start()
  {
      gameObject.GetComponent.<ParticleSystemRenderer>().material = newMat;
  }

this worked for me but in built game you should put a list of shaders to build in settings or put the min a built scene that can never navigate to xD`using System.Collections; using System.Collections.Generic; using UnityEngine;

public class ShaderBrinisFixe : MonoBehaviour {

 // Create a material from code
 public void FixeSahders()
 {
     // Create a material with transparent diffuse shader
    
     // assign the material to the renderer
     foreach (ParticleSystemRenderer p in gameObject.GetComponentsInChildren<ParticleSystemRenderer>())
     {
         p.material.shader= Shader.Find(p.material.shader.name);
     }
 }

} `
