Support for More than 4 Controllers


I have been trying to get 6 player local to work in my project but so far seem to be limited to a maximum of 4 controllers.
The 6 controllers are properly synced and I have successfully debugged GameInstance CreateLocalPlayer, nothing seems to be amiss for the last two players, their pawns are created and update as expected, however the last 2 controllers do nothing. Is this a known limitation? Is there anything I can hack to allow this to work? It’s a Smash Bros type game so I would be looking at supporting up to 8 game pads in the future.

Thanks for any input!!
