Hello again Frank and sorry for the late reply due to summer vacation.
Actually, (and technically) the GraphOwner component CAN reference another blackboard, one that is not attached on the same gameobject as the GraphOwner component is. GUI-wise however, this is not possible since there is not “Blackboard” Object field to assign a different blackboard.
This is why I am thinking of instead of enforcing the use of the Blackboard only attached to the same gameobject, to rather expose an Object Field to assign any blackboard regardless of which gameobject it is attached on, since it is technically possible and may have some nice use cases as well, like sharing a single Blackboard between multiple GraphOwner (something that was actually possible many versions back). 🙂
