I have a problem I use to render a scene with open gl and than use glReadPixels to save the current framebuffer. What I want to achieve is to display something on the screen but saving something different with glReadPixels, is that possible? I am rendering a scene with visual debug output for the user in the scene but what I want to save does not contain the debug output, so what I try to achieve is to create a copy of my scene without some output and save that. I can't use the user view for that since this would flicker to much ( I need several operations without the debug output) Can I create a user specified buffer or something like that?

That did it, thanks !
