Offscreen-only rendering

Hello! I’m looking to use UE4 to do offscreen-only rendering and would like to read the framebuffer contents to CPU memory after each frame has finished rendering and do something with it. Where do I begin? Does this require me to change engine sources or will a simple plugin/modification to the game project sources suffice?

Pointers are most appreciated, thanks in advance!

Depending on what exactly you’re trying to achieve, you could take a look at how Canvas is used for the mini-map in StrategyGame (available for free in the Marketplace). Does that help?

Could use some help here, too… The StrategyGame is no longer available and I’d really like to copy the framebuffer so that I can stream the game video.
