How to undo a Ctrl T tracking command?

I’ve tracked a light and camera to an object, and now need to undo it, and change the tracking to a different object. . I have searched wiki and here to no avail. Can anyone help?


simply do Alt-T and remoe track constraint


With the objects selected, Object => Constraints => Clear Constraints.

ALT+T should do it too, but I find it doesn’t.

Thanks organic. I actually tried alt T on a whim but i didn’t think it worked because the dashed line still pointed to the target object. and in fact it still does even after I tracked t he light to a new mesh.
thanks much!!

I believe you should also be able to edit and remove individual constraints from the Constraints tab on the Object button bar (F7) in Object mode.
