Just trying to understand what the difference is between the components in these two sections, and why sometimes when I add a new component they are positioned at the bottom with CharacterMovement and other times as children of CapsuleComponent.
Movement, AI perception are considered “non-scene components”, they have no physical representation (i.e relative offset within the Blueprint actor etc…).
Therefore when you add these to the blueprint they are shown outside of the scene component tree (children of scene components have relative location based on their paren’ts location).
