Same scene in multiple viewports? Without re-render?

Hello,

I’m new to this list. Greetings!

I’d like to display a copy of my rendered scene in two viewports - one on my laptop screen for monitoring, and the other to an external monitor for display. Does anyone know how I can do this without having to render each frame twice? The typical use for multiple viewports is to display multiple views from different angles or other settings that require a re-rendering of the scene, but I don’t need that, so don’t want to take the cpu/gpu to render the scene twice if I don’t have to.

Thanks for any tips.

Cheers,
Michael

Render the scene to a FBO, then you can draw the resulting texture as many times as you want.

Thanks, that sounds like the thing to do!
