i need to show my model above a background, but when i use the bloom filter, it affects the image.
tried drawing the view to a bitmapdata and removing the black, but when the filter is used, the technique of

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

still raises the error “All buffers need to be cleared every frame before drawing”

any ideas?

i have been using imaging application to filter image files and they are working great. but as for background image, i need some mature image processing tool for that.
