[away3d] Away3D 4.0 render to a Bitmap

[iiley Chen]

Hi,

After some experiences, i realize that the Stage3D is under normal
DisplayObjects, but my project need to view the 3D content in front of
them.
I tried to do this:
add a bitmap in front of my other objects.
Then after view.render()
call
Stage3DManager.getInstance(stage).getStage3DProxy(0).context3D.drawToBitmapData(canvas.bitmapData);

But there is no effect.
Any help will be appreciated.
