I’ve spent some more time looking into your project, and it’s still a bit difficult to determine exactly what the issue is.
Do you notice that the debug “ball” (the one that should rest on a perceived actor), for lack of a better word, moves as you move the camera? It doesn’t actually seem to attach to the perceived actor. Is this the same behavior you are experiencing?
Also, I upgraded the project to 4.11 Preview 3, and the perception seemed to be functioning properly. Although there were other errors that appeared as a result of the conversion, the perception was registering much more clearly. Give that a shot and see if you can get the same results.
