Hello everyone!
Need to render the scene in a bitmap without a background.
In previous versions, it is possible to do by using these steps:

view.renderer.swapBackBuffer = false;
view.render ();
view.stage3DProxy.context3D.drawToBitmapData (bitmapData);
view.renderer.swapBackBuffer = true;

Now using version 4.1.4.
In this version, not possible to do the same, as the “renderer” does not have the property “swapBackBufferr”.

If use the “queueSnapshot ()” I get a screenshot of the scene with the background.

Is it possible to make a screenshot of the scene without the background?

Thank you!

i think that you could do (it’s not so good but maybe works):

view.backgroundAlpha = 0;
view.renderer.queueSnapshot (bitmap);
view.render();
view.backgroundAlpha = 1;
