And one more way to do it without touching code:
In your character blueprint’s EventGraph, right click and find Get Follow Camera Component. Drag off that node and type Set PostProcessSettings. Off that Set node, drag off Post Process Settings and type Make PostProcessSettings. If you expand that node, you’ll see a huge list of all post process settings you can adjust for that camera.
Included within that list are Auto Exposure Min Brightness and Auto Exposure Max Brightness inputs. Promote those to variables and give each of those variables a default value of 1, as described above, and that will disable Eye Adjustment for that camera, without having to touch any code.
