I have made a change to the hierarchy editor, when you drag and drop a node onto a new parent node, the location in the world of the object that you are dragging will no longer change. Before this change the object would suddenly move if the new parent has a different transformation applied to it, for example because it is animated. Now the hierarchy editor calculate the correct transformation so that the location in the world of the node no longer changes. This should make it easier to add attachpoints to animated parts or change the general structure of a model.
