I’m at work right now so I’m going off of total memory, so bear with me. If you still need help, I can pull up some screenshots when it get home. Go to Edit (top left)>Project Settings>Gameplay Debugger. The setting is in there and this is where it gets hazy for me without looking at it, there’s a dropdown in there with several elements, there will be AI perception components in there. Those can be dropped down as well, and there are options in there (under more dropdowns) to make visible in game and editor. Then just press the “apostrophe” key (next to enter) while the game is running and the debug screen should show up.
Sorry about being so vague, I don’t have a good memory and I remember trying to figure it out myself and got it working.
