Copy content from backbuffer to FBO?

Is it possible to copy contents from the backbuffer into a FBO?

How bad would that be in terms of performance?

I want to do this since I want to use the stencilbuffer, but its not available in my FBO’s…

there is a renderer.copyFrameBuffer method. Performance wise it’s a lot faster that a render pass, and since it’s the only other option you have, that’s definitely the way to go :wink:
