Hey Yun-Kun,
Great to hear from you and nice that you’ve found time to use the minimap! From your screenshots (very helpful, ty) it seems that the minimap center (controlled by the MapView comp) and the character’s icon (controlled by the MapIcon comp) are both at wrong positions. Can you please post a screenshot of your character’s component hierarchy? Are the MapView and MapIcon currently direct children of the character’s mesh? If they aren’t, perhaps that would help.
You can call the MapBackground actor’s GenerateSnapshot() function to recapture the image at run-time. You can also check its SceneCaptureComponent’s setting bCaptureEveryFrame if you want the minimap to show a live image, although obviously that renders the scene twice every tick.
