You need to backup the original position in world space and set this after insertion. Easiest done by storing the global matrix (GetMg() and then later SetMg()).


An object only knows about its relative position (relative to the parenting object, that is). Its global position in world space is not stored anywhere, but is the result of the "accumulated" positions of all parents in the hierarchy and the object's relative position (same for scale and rotation of course).

By just changing the object's position in  the hierarchy, it will keep its relative position, which in combination with the new parent leads to a new position in world space.
