Hi!

I´m new on Away3d and I was trying to learn the basics. I found this tutorial from GotoAndLearn - TUTORIAL LINK

It was working flawless until I tried to set SkyBoxMaterial on the cube. When I run the code, the cube dissapear. If I set ColorMaterial the cube shows normaly.

I´m coding on FlashBuilder 4.6 with FP11.

Thank you!

Oh the problem is that you shouldn’t use a cube but a SkyBox instance.

SkyBoxMaterial is used internally by SkyBox and you should never instantiate it directly.

var skyBox : SkyBox = new SkyBox(cubeTexture);

scene.addChild(skyBox);

That´s my problem. I´m struggling to find a way to texturize my cube. Since the way they teach on that video doesn´t work….

Thank you for help!

I just figured out how to apply texture to a cube. Wasn´t like the video where that guy used separated images files for each cube face.

I manage to use a single image with all faces on it. Unless I can place my camera outside the SkyBox, I think I´ll have to stick with that!

Peace

Ed,

If you want to use six different images for your skybox, successfully I use the following code in FlashBuilder 4.6 FP11.7 Away3D Gold 4.1.4

Hope this helps!

<fx:Script>
  <![CDATA[
   import away3d.primitives.SkyBox;
   import away3d.textures.BitmapCubeTexture;
   import away3d.utils.Cast;
   
   // Skybox textures.
   [Embed(source="../embeds/space_posX.png")]
   private var PosX:Class;  
   [Embed(source="../embeds/space_negX.png")]
   private var NegX:Class; 
   [Embed(source="../embeds/space_posY.png")]
   private var PosY:Class;
   [Embed(source="../embeds/space_negY.png")]
   private var NegY:Class;
   [Embed(source="../embeds/space_posZ.png")]
   private var PosZ:Class;
   [Embed(source="../embeds/space_negZ.png")]
   private var NegZ:Class;
   private var skyBox:SkyBox; 
   private var cubeTexture:BitmapCubeTexture;
   
   public function init():void
   {
    createDeepSpace();
   }
   
   private function createDeepSpace():void {
    // Cube texture.
    cubeTexture = new BitmapCubeTexture(
     Cast.bitmapData( PosX ), Cast.bitmapData( NegX ),
     Cast.bitmapData( PosY ), Cast.bitmapData( NegY ),
     Cast.bitmapData( PosZ ), Cast.bitmapData( NegZ ) );
    // Skybox geometry.
    skyBox = new SkyBox( cubeTexture );
    away.view.scene.addChild( skyBox );
   }
  ]]>

@GrokDD: he want’s to apply 6 different images to a cube, this thread has nothing to do with skyboxes…

@Ed: Forget SkyBoxes and SkyBoxMaterials, they aren’t made for what you want to do.

That´s right SharpEdge!
I figured how to apply texture to a cube… saddly I can´t have separated images for each face. Maybe that tutorial video was made using a Away3D beta version…

Thank you for helping!

Peace!

A solution could be to create your cubic texture dinamically taking six images and drawing all of them in one bitmap.

Found this dirty solution, you’ll get six draw call and that’s not so good if you have complex scene.

Indeed… not so good for complex scenes. But works pretty nice for what I need right now! Ill give a try!!

Thanks!
