For one of the most basic shader examples, we will be learning about the Composite Shader, this basicaly gives your object a solid color with wireframe showing.

Composite Material Example

Composite Material Example

If you are a beginner to PV3D/Flash, My examples will be working from my initial post on Shaders which can be found here.
Otherwise please feel free to continue. 

Firstly we will need to import all necessary classes

package compositeMat {
	import flash.display.Sprite;
	import flash.text.TextField;
	import flash.text.TextFormat;

	import org.papervision3d.cameras.CameraType;
	import org.papervision3d.materials.ColorMaterial;
	import org.papervision3d.materials.WireframeMaterial;
	import org.papervision3d.materials.special.CompositeMaterial;
	import org.papervision3d.materials.utils.MaterialsList;
	import org.papervision3d.objects.primitives.Sphere;
	import org.papervision3d.render.BasicRenderEngine;
	import org.papervision3d.view.BasicView;

        import org.papervision3d.objects.parsers.DAE;
        import org.papervision3d.objects.DisplayObject3D;

Next we will pass the class, and the variables that we will be using

public class compositeMat extends Sprite
		private var view:BasicView;
		private var color:ColorMaterial;
		private var wire:WireframeMaterial;
		private var composite:CompositeMaterial;
		private var sphere:Sphere;

		private var tf:TextField;
		private var format:TextFormat;

		 private var dae:DAE;
                private var daeFile:String;
                private var daeMaterialName:String;

And we will now finish off with our functions

public function compositeMat()
//controls camera size initialises BasicView
view = new BasicView(300, 300, false, false, CameraType.FREE);
//Sets up Rendering Engine
view.renderer = new BasicRenderEngine(); addChild(view);
//Select colours for Wireframe and object
color = new ColorMaterial(0x444444);
wire = new WireframeMaterial(0x888888);
composite = new CompositeMaterial();
//Loading your .dae File
daeFile = "yourdaeFileName.dae";
dae = new DAE();
//adding the composite shader ontop of your DAE model
dae.load(daeFile,  new MaterialsList ( { all:composite } ));
//sometimes object needs to be scaled
dae.scale = 100;

//adding the object to the scene

//Formating and adding text label to the scene.
format = new TextFormat("Arial", 10, 0xFFFFFF);
tf = new TextField(); tf.width = 230; tf.text = "Composite Material Shader";
tf.x = 10; tf.y = 10; tf.setTextFormat(format);
addEventListener(Event.ENTER_FRAME, onRenderViewport);

private function onRenderViewport(e:Event):void
//If you want your object to rotate on its axis
//Finaly render

Now if you are following this example on from my Introductory post on Shaders, you will need to import this .as file into you file by typing in the following:

package {
	import org.papervision3d.render.BasicRenderEngine;
	import org.papervision3d.view.BasicView;

	import compositeMat.compositeMat; //IMPORTANT importing the Shader AS file
	import flash.display.Sprite;

	[SWF (width="800", height="600", framerate="25", backgroundColor="0x333333")];

	public class MainShader extends Sprite {
		private var composite:compositeMat;

		public function MainShader() {
			composite = new compositeMat();

Now that you have imported your file into you file, which is linked to whateveryoucallyourFLA.fla file you can press ctrl + shift + Enter to compile and debug your code or
ctrl + Enter to run your movie.
