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