When I right click in the content browser I can’t find anything related to the BehaviorTree assets like I could in older versions of UE4. I even tried selecting Blueprint Class and searching for “Behavior” and “Blackboard”, but with no luck.
It is there, at the bottom of the context menu under Artificial Intelligence. You just nee to scroll down. Check out this post: user interface and WidgetBlueprint is missing in 4.9.2??? - UI - Unreal Engine Forums
I feel so stupid right now, haha. Sorry for posting this question.
