How to position an object to the centre of camera’s viewport in the scene (for example position camera wherever you want and toggle preview of it by pressing NUMPAD 0). So basically position object to the centre relative to the preview camera viewport. Thanks.
This method centers the object's origin in the camera viewport. If you want to center the geometry position its origin at the center of mass first.⎈ Ctrl⇧ Shift⎇ AltS
The green circle indicates the desired position. The plane (perpendicular to the camera) indicates where the object is supposed to move.
- Snap the cursor to the camera.
- Set the Pivot Point to 3D Cursor.
- RMB select the empty and scale it to zero along its local XY plane.
S > ⇧ ShiftZ > ⇧ ShiftZ > 0
- Snap the cursor the the empty, then the object to the cursor.
