The current system isn’t really set up that way, but one thing you could do is define a character for each team in BP_GameInstance and then in BP_PlayerCharacter in what I believe is UpdatePawnVisuals you can use the team num as a character index instead of the player’s chosen character index. I’ll consider adding better support for this in the future.
Both these have been fixed in an update I just submitted. Thanks for bringing this up.
In the update I just submitted I have added resolution options. Different settings are applied in different ways, mostly through the use of console commands. This logic will be updated when 4.11 is released as 4.11 adds some more explicit settings nodes in BP.
