[Papervision3D] Effects branch ParticleField

[-a-]

Hi Andy,
Sorry about this but, I cannot seem to find my blur on the 
ParticleField. Can you give this the once over?

a/

    public function createFXLayer():void
    {
        //CREATE THE EFFECT LAYER
            _fx = new EffectLayer();
            //_vport.addRenderLayer(_fx);
           
            //_fx.addEffect(new LayerEffect(new BlurFilter(12, 12, 4)));
            //_fx.addEffect(new LayerEffect(new GlowFilter(0xff0000)));
           
            _bfx = new BitmapEffectLayer(_c.width,_c.height, true, 0, 
BitmapClearMode.CLEAR_POST, true, false);
            _bfx.addEffect(new BitmapLayerEffect(new BlurFilter(6, 4, 
4), false));
            _vport.addRenderLayer(_bfx);
       
            _bfx.drawCommand = new BitmapDrawCommand(null, new 
ColorTransform(0.1, 1, 0.1, 0.25), BlendMode.ADD);
           
           
           
    }
