How to find and assign Default-Particle material to a renderer

As I tend to go on and over-explain things, here is the short point version =]

• I am writing a script =]

• From a Menu Item I am creating a gameObject

• To this gameObject I am adding : MeshFilter, "EllipsoidParticleEmitter", ParticleAnimator, ParticleRenderer

• To the ParticleRenderer, I wish to assign the material Default-Particle

How do I find and then assign the material Default-Particle to the ParticleRenderer from a Menu Item, not runtime. Thanks.

Here is my current script :

 @MenuItem("Custom/Particles/Mesh Emitter")
 static function newParticleMesh() 
 {
     var go : GameObject = new GameObject( "LegacyParticleMesh" );
     go.transform.position = Vector3.zero;
     go.AddComponent( MeshFilter );
     go.AddComponent( "MeshParticleEmitter" ); // as ParticleEmitter;
     go.AddComponent( ParticleAnimator );
     go.AddComponent( ParticleRenderer );
     
     //go.renderer.material.shader = Shader.Find("Particles/Alpha Blended Premultiply");
     //go.renderer.sharedMaterial.shader = Shader.Find("Particles/Alpha Blended Premultiply");
 }

Original Question :

How do I find and assign a native material and shader to a renderer? I am talking about the Default-Particle material that comes with Unity.

I am creating a custom menu item for legacy particle objects. Everything is fine except for when I want to apply Unitys native Default-Particle material.

when I use :

 go.renderer.material.shader = Shader.Find("Particles/Alpha Blended Premultiply");

this is the error message :

Instantiating material due to calling renderer.material during edit mode. This will leak materials into the scene. You most likely want to use renderer.sharedMaterial instead. UnityEngine.Renderer:get_material() CustomParticles:newParticleMesh() (at Assets/Editor/CustomParticles.js:27)

when I use :

 go.renderer.sharedMaterial.shader = Shader.Find("Particles/Alpha Blended Premultiply");

this is the error message :

NullReferenceException CustomParticles.newParticleMesh () (at Assets/Editor/CustomParticles.js:27)

I am trying to find and apply the Default-Particle texture with the default Alpha Blended Premultiply shader. How is the correct way to assign these to the particle renderer using script/code?

Like these ones =]

unity how to find and assign default particle material

here is the code :

 #pragma strict
 
 #if UNITY_EDITOR
 
 // -- Custom / Particles --
 
 @MenuItem("Custom/Particles/Ellipsoid Emitter")
 static function newParticleEllipsoid() 
 {
     var go : GameObject = new GameObject( "LegacyParticleEllipsoid" );
     go.transform.position = Vector3.zero;
     go.AddComponent( "EllipsoidParticleEmitter" );
     go.AddComponent( ParticleAnimator );
     go.AddComponent( ParticleRenderer );
 }
 
 @MenuItem("Custom/Particles/Mesh Emitter")
 static function newParticleMesh() 
 {
     var go : GameObject = new GameObject( "LegacyParticleMesh" );
     go.transform.position = Vector3.zero;
     go.AddComponent( MeshFilter );
     go.AddComponent( "MeshParticleEmitter" );
     go.AddComponent( ParticleAnimator );
     go.AddComponent( ParticleRenderer );
     
     go.renderer.sharedMaterial.shader = Shader.Find("Particles/Alpha Blended Premultiply");
 }
