Where i have to work to manage video output??

Hi all i’m tryinig to make a slti screen output for 3d TVs.
So i need to make something very similar to oculus:
3d tv split the video input in 2 part and use the difference from two part of input to create 3d dense.
So i would avoid to use some trick to make this, and i would take the output of 2 cameras and merge in video output.
so now the real question where i should go to work to achive my goals?

You could use splitscreen, you can set it up in GameClientViewport class. But not surehow its gonna be compatible with 3dtvs

mmm… but viewport don’t was the one in the editor?
at this point is better try user multiplayer splitscreen or i wrong?
