Simple Cube w/Texture

Hey all,

I’m new developing with Papervision3d (though not new to Flash/Flex/Actionscript) and have a really basic problem. I was able to display my first code-generated plane and rotate it, and also load a model collada file built with Swift3d.  Now I am trying to create a box with texture, but having problems.  Here is the relevant part of my code:

(CubeTexture is a bitmap in Flash CS3 with linkage exported as class: CubeTexture and base class: flash.display.BitmapData)

var bitmap:Bitmap = new Bitmap(new CubeTexture(0,0));

material = new MaterialObject3D();

material.bitmap = bitmap.bitmapData;

materials = new MaterialsList();

materials.addMaterial(material);

primitive = new Cube(materials, 200, 200, 200);

scene.addChild(primitive);

I get this error:

“WARNING: Required material not found in given materials list. Supported materials are: front, back, right, left, top, bottom & all.”

Any ideas what I’m doing wrong?  Thanks.
