I remember years ago on older udk version that I used to go in the GameViewportClient.uc and replace the two lines ActiveSplitscreenType =
with ActiveSplitscreenType = eSST_2P_HORIZONTAL
And in udk in what ever type of game mode, i will just quickly console command DebugCreatePlayer 2 and will have a quick split screen for 2 players to test.It was long ago but i think that’s how i did it.
Today i tried it on one of the last 2013 udks and it doesn’t seem to work.
Was there anything more to it for a quick test or am i remembering the old ut3 editor?
