Changing the pivot of a model

I have inserted a model that has sub models. However the pivot for the whole model is not at the center of the model. How do I shift it to center of the model.

I have tried recreating the model but it was not helpful.


What I usually do is adding the “uncentered” model into a new parent entity, then just move the child till its centered. If you now manipulate the new parent entity, the child will behave as if its centered.

A second way would be to import it in e.g. Blender, fix pivot, export again.
