as the question states. im missing all 3 of those blueprint classes in my 4.9.2 unreal engine. i have extensively searched for an answer and cannot find anything about it. looking at the documents it shows there is another blueprint tab below paper2D that is called Artificial Intelligence. i also know that in earlier versions Blackboard and Behavior tree existed in the Miscellaneous Blueprint tab but they dont exist there either. ive also tried searching for them but to no avail. ive tried reinstalling but no success there. does anyone know where these blueprints exist? how can i make AI without them?
wow your right. the only way to see ai is to right click on teh content and add new asset. no way from the add new tab or from the toolbar at the top
After right click into content browser just scroll down little bit, and you will see Artificial Intelligence category.
