Depth3D for 4 or 3 player Split screen games

[griduser64]

Is it possible to modify the shader to display 3d depth on a single game that runs in split screen for 3 or 4 players?

I tried using it on a game like Mario Kart 8 with Yuzu emulator and if its not in split screen local multiplayer then the shader works just fine showing the 3D.

When I have three or four players in a local split screen then the shader shows only one depth map that's covers the entire screen instead of rendering a depth map with split screens for each individual screen.

Is this even possible?
