AI perception doesn't work as expected

I add [/Script/AIModule.AISense_Sight] bAutoRegisterAllPawnsAsSources=false in DefaultEngine.ini and it doesn’t seem to work. AI still can see the pawns without AIPerceptionStimuliComponent. When there are more than 6 pawns in AI’s Vision, Ai seems can’t follow up all the pawns. The pawn that far from AI shows that age is 0.30, not 0.00.

I uploaded my test project [here][1]

Is your AIPerception component set up on the pawn or on the controller? If it’s the pawn, then it might auto-register itself there as a source. It’s recommended to add AIPerception to the corresponding Controller.

Thanks for your answer. But my AIPerception component is set up on the controller. I am troubled by this problem for a whole year, but I can not find a solution. Thank you for your answer.

Have you solved the problem?

It’s years later but for reference I solved this issue by changing the AIPerception from the Pawn toi the AIController, and putting the command:

[/Script/AIModule.AISense_Sight]
bAutoRegisterAllPawnsAsSources=false

Both in DefaultEngine.ini and DefautGame.ini
And restarting the editor
