We have a 4-player splitscreen set up with controllers, but for whatever reason the first player is not controllable and the camera moves into the ground. I have had similar experiences with Game Maker when coding spawn points, where the door for the first one specifically would never open. Is there something in regards to 0th player or something that engines just don’t handle properly?
Spawning is handled in blueprint, though not done on the player blueprint itself, but a manger. We do use c++ for character movement and camera assigning, however.
