    Hello,
    I tried to use the logo example for a 3d space, but didn't get it to work.
    I followed the example and changed all parameters for 3d. I guess my problem is with the 3D BitmapDataZone.
    I guess I'm using the parameters the wrong way. Can you help me?

    Here is my code. Everything works fine with the BoxZone Initializer, so I think the problem is the BitmapDataZone.

    import org.flintparticles.common.actions.*;
    import org.flintparticles.common.counters.*;
    import org.flintparticles.common.easing.Quadratic;
    import org.flintparticles.common.events.EmitterEvent;
    import org.flintparticles.common.initializers.*;
    import org.flintparticles.common.displayObjects.Rect;
    import org.flintparticles.threeD.actions.*;
    import org.flintparticles.threeD.initializers.*;
    import org.flintparticles.threeD.zones.*;
    import org.flintparticles.threeD.emitters.Emitter3D;
    import org.flintparticles.threeD.renderers.*;
    import org.flintparticles.threeD.renderers.controllers.*;

    var logoClip : MovieClip = new Logo();
    var logo:BitmapData = new BitmapData(260, 250, true, 0x00FFFFFF);
    logo.draw(logoClip);

    var emitter:Emitter3D = new Emitter3D();
    emitter.counter = new Steady( 30 );
    emitter.addInitializer( new SharedImage( new Rect( 10, 10 ) ) );
    emitter.addInitializer( new Lifetime( 3 ) );
    emitter.addInitializer( new Position( new BitmapDataZone( logo, new Vector3D( 0, 0, 0 ), new Vector3D( 260, 0, 0 ), new Vector3D( 0, 250, 0 ) ) ) );
    //emitter.addInitializer( new Position( new BoxZone( 280, 280, 280, new Vector3D( 0, 0, 0 ), new Vector3D( 0, 1, 0 ), new Vector3D( 0, 0, 1 ) ) ) );
    emitter.addInitializer( new Velocity( new PointZone( new Vector3D( 0, 0, -200 ) ) ) );

    emitter.addAction( new Move( ) );
    emitter.addAction( new Age( Quadratic.easeOut ) );
    emitter.addAction( new Fade( 1, 0 ) );
    emitter.addAction( new LinearDrag( 0.5 ) );
    emitter.start( );

    var renderer:BitmapRenderer = new BitmapRenderer( new Rectangle( 0, 0, stage.stageWidth, stage.stageHeight ) );
    renderer.addFilter( new BlurFilter( 2, 2, 1 ) );
    renderer.addFilter( new ColorMatrixFilter( [ 1,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0.66,0 ] ) );
    renderer.addEmitter( emitter );
    renderer.x = 0;
    renderer.y = 0;
    addChild( renderer );

    renderer.camera.position = new Vector3D( 0, 0, -400 );
    renderer.camera.target = new Vector3D( 0, 0, 0 );
    renderer.camera.projectionDistance = 400;
    var camera = new FirstPersonCamera( stage, renderer.camera );
    camera.start();

    problem found! The "getLocation" function inside the BitmapDataZone Class was wrong.
    I'm surprised that no one has noticed that before.
    I fixed it with this code:

    public function getLocation():Vector3D
    {
    if( _dirty )
    {
    init();
    }

    var point:Point = Point( _validPoints.getRandomValue() ).clone();
    var d1:Vector3D = _scaledWidth.clone();
    d1.scaleBy( point.x );
    var d2:Vector3D = _scaledHeight.clone();
    d2.scaleBy( point.y );
    d1.incrementBy( d2 );
    var pos = _corner.clone().add( d1 );
    return pos;
    }

    Thanks. I've added the fix to the github repository.

    I get this when I try to run your code:
    1067: Implicit coercion of a value of type Logo to an unrelated type flash.display:MovieClip.
