    Mobile game engines usually have a method of drawing touch trajectories, which is similar to desktop mice. We haven’t found a similar case with Threejs yet. It should be achieved by recording touch trajectories and then drawing them on the screen using Canvs

    Yes, your Blender export is correct. I had suspected an issue with the matrix transformation in the update function of OrbitControls. if (i.targetObj.updateWorldMatrix(!0, !1).

    I hope someone can verify whether this is indeed a bug that exists only in the Max version.

    I’ve uploaded a demo that uses the default controls with the method I used last night. Please take a look. Shanks KDV

    I used 3dsMax, and the principle should be the same as what you described. I tried both methods, and the result is similar to the demo I provided earlier. The camera follows the parent object and always faces the target object, which is correct. However, the issue arises when the target object moves away from the origin—the orbit path becomes strange. Could it be a bug specific to the Max version?

    Great! This is the effect I wanted, thank you, KDV! Is this constraint set up in 3D software beforehand? Because I couldn’t find this part in the JavaScript logic. Could you display the key code or logic for this? My confusion is, if the character and the camera are not grouped, how does the camera follow the character? The target point of the camera can be constrained to the position of the character. Can you please advise on how to set up the camera? Thanks again, KDV.
