After adding the camera to object3d, the camera is following the object on the way that I want, but when the object position go far from (0,0,0) the camera not rotating correctly, I found that the camera position always targeting the object on the position (0,0,0) while the target on the orbitcontrol is the real object position eg. (121.1, 1, 34.32).
I am wondering how I can achieve this with camera under Object3d!
the follow cam just working fine with the quaternion
(follow object and slerp the goal with the quaternion) … but the rotation when I Orbit the looking angle so weird…
