How can I parent the AIPerception to a characters mesh so that when he ducks, the base position of AIPerception decreases? I currently have my AIPerception component in my AIController and am running 4.8 preview 2.
Assuming your controller is controlling a pawn of type ACharacter and you’re using the built in crouching functionality, this should work automatically by way of the CrouchedEyeHeight property. If it doesn’t then it’s probably a bug - this stuff is undergoing a lot of changes at the moment.
