I have the same problem, and I create this bug emulation but I still waiting for a resolution:
http://developersuniverse.com/away3d/BugReproducer.zip In this files, the problem comes when some objects leaves the range of view of the camera. If any person doesnt trust on my my zip file, I post the code below: Away3dApplication.as (for all my away3d applications)--------------------------------------------------------------------------------------- package { import away3d.cameras.Camera3D; import away3d.containers.ObjectContainer3D; import away3d.containers.Scene3D; import away3d.containers.View3D; import away3d.core.render.Renderer; import flash.display.Sprite; import flash.events.Event; public class Away3dApplication extends Sprite { protected var _scene:Scene3D; protected var _camera:Camera3D; protected var _view:View3D; protected var _container:ObjectContainer3D; public function Away3dApplication(){ initEngine(); initListeners(); } public function resetCamera ():void{ //_camera.y = 0; _camera.x = 0; _camera.z = 0; //_camera.lookAt(_container.position); } protected function initEngine():void{ _scene = new Scene3D(); _camera = new Camera3D({zoom:10, focus:50, x:0, y:-500, z:-250}); _view = new View3D({scene:_scene, camera:_camera, renderer:Renderer.INTERSECTING_OBJECTS}); _view.x = 400; _view.y = 300; addChild( _view ); _container = new ObjectContainer3D (); _scene.addChild( _container ); _camera.lookAt( _container.position); } /** * Initialise the listeners */ protected function initListeners():void{ addEventListener( Event.ENTER_FRAME, onEnterFrame ); } /** * Render loop */ protected function onEnterFrame( $event:Event ):void{ _view.render(); } } } on BugReproducer.as file ------------------------------------------------------------------------------------------------------------------- package { import away3d.core.utils.Cast; import away3d.materials.BitmapMaterial; import away3d.primitives.Cube; import away3d.primitives.Plane; import flash.display.Sprite; import flash.events.Event; public class BugReproducer extends Away3dApplication{ //use any jpg, who cares!! [Embed(source="brick.jpg")] private var _brick:Class public function BugReproducer(){ initObjects (); } public function initObjects ():void{ var material:BitmapMaterial = new BitmapMaterial( Cast.bitmap(_brick) ); var plane:Plane = new Plane({material: material, width:1000, height: 500, segmentsW:4, segmentsH:4, yUp:false}); _container.addChild(plane); for (var i:int =1 ; i< 10; i++){ var newCube:Cube = getTestCube(material); _container.addChild(newCube); } _camera.y = -1000; } protected function getTestCube($material:BitmapMaterial):Cube{ var newcube:Cube = new Cube({material: $material, width:50, height: 50}); newcube.rotationX = 90; newcube.x = randomRange(-300, 300); newcube.z = -200 newcube.y = randomRange(-150, 100); return newcube; } protected function randomRange ($min:Number, $max:Number):Number{ var randomNum:Number = Math.floor(Math.random() * ($max - $min + 1)) + $min; return randomNum; } protected override function onEnterFrame($event:Event):void{ _container.x +=10; super.onEnterFrame($event); } } } ------------------------------------------ Just create one instance of BugReproducer, and add it to display list: var bugEmulator:BugReproducer = new BugReproducer (); addChild(bugEmulator);
