I am sorry, this is really a Modding question but since I am new here, I don’t have permissions to post in that sub-forum 
Anyway! I am just getting started though 
I am completly new to the Unreal Engine and Modding world. I have only been investigating for a day but I don’t know if what I am trying to do, although it sounds easy, is actualy very hard to do. 
First of all, I want to clarify that I just want to make a slight change to Unreal Engine 4 games I bought on Steam or Epic…for myself. I have no intention to release mods to the public nor infringe any copyright or steal anything from the developers.
So here is the situation: I realy enjoy playing third person games on tripple screens, so an aspect ratio of 48:9. I know, it is not tipical but I am also not the only one who likes it, because things like Flawless Widescreen and WSGF.org exist Most games either support it perfectly out of the box or I get working with FWS or some other mod or trick. However, there are some games I still am unable to play for one simple reason…the placement of some UI elements all the way in the borders of the outside screens. I am refering to the HUD, minimap, messages, etc. To play on tripple screens, all UI elements must be on the center screen. The outer screens are just for peripheral vision.
So de question is: How can I force UI elements of an existing game to stick to the central 1920x1080 screen, eventhough the resolution is 5760x1080?
To try, I am using the game Evil West which uses UE4.26. I have been able to save some .uasset and .uexp files from the game but when I use them in Unreal Engine they are not really showing anything and there are so many of them that I don’t really know which one is in charge of placing the UI elements. I suppose I would need to find one or multiple Widget Blueprints, but I don’t even know if they can be extracted.
I thought this should be a very unintrusive change, but is this even possible??
Thanks in advance for any help!!
