How to Center Camera on a Parent Object

Hi,

I have child objects stacked vertically. Using the standard camera orbit code, the camera always focuses on the base of the parent Game Object, not the center.

Also, if I remove the lowest child GameObject, the camera is still pointed at the original bottom as it the lowest child GameObject was still there.

Finally, all rotation is around the bottom of the parent GameObject, which I suspect is the same issue.

There is no geometry in the parent GameObject, only in the children.
The models are all built with the center on the bottom of the model.
The models simple cylinders.

I have read up on pivot points, but am still having the above issues and would appreciate any additional ideas, hints or solutions.
Thanks!
Joe

Still going crazy with this, so giving the thread a bump. Thanks!
