Thanks for the snippet Rob. Unfortunately, some weird things are
happening that I cant explain. The material library comes back null
and when I trace out myObject I get "$: x:0 y:0 z:0" I have
successfully added the object to the stage and it shows up fine, but
whenever I try to trace any properties everything comes back null.
This is the function:
private function onObjLoaded( e:Loader3DEvent ):void
{
_obj = e.loader.handle;
_obj.scaleX = -1;
var matData:MaterialData = matLib.getMaterial(
"Material1" );
trace( matData );
var bitmapMat:BitmapMaterial = matData.material as
BitmapMaterial;
trace( bitmapMat );
matData.material = new
WhiteShadingBitmapMaterial( bitmapMat.bitmap );
_scene.addChild( _obj );
addEventListener( Event.ENTER_FRAME, onRender );
}
