I see. Well in esence this is exactly what the disable/enable rendering should do. All it does, and the Verge team might correct me on the fine details here, is to not update the buffer or whatever aslong as the rendering is disabled, basicaly holding the last frame as a screenshot. As long as you don’t clear the buffer or write anything new to it it should stay unchanged until you re-enable rendering. But that is neither here nor there if disabled renderer will prevent the scene form being updated like Yuri said. Then you would probably have to manualy stor the buffer and force it as the last update before finalising the renderloop, or even map it to a shaderless mesh right in front of your camera or something.
A quicker and maybe not so elegant way would be to have your changes made to an object of screen, if you can hide it under the floor or somewhere out of sight whiles you make the changes, even scaling it down to make it fit inside something else, and then swap it with the old object in one go, when all is set up ? basicaly just set position of new object to the old objects position, and the old object position to the of screen location where the new one was set up. Doing this in two cosecutive lines of code should make the change in location between the same two consecutive render loops/frames.
Might that be a posible solution? Not very elegant, but then again 3D stuff is mostyly about cheating your way around limitations anyway ;)
