When one or more incoming objects have the same name as objects in the scene, an alert gives you the following options:
Merges the incoming object using the name in the field at the right. To avoid having two objects with the same name, type a new name before proceeding.
Does not merge the incoming object.
Deletes the existing object before merging the incoming one.
Treats all subsequent incoming objects with duplicate names the same way you specified for the current object. No further alerts will appear. This option is not available if you renamed the current object.
Cancels the merge operation.
When one or more materials assigned to incoming objects have the same name as materials in the scene, an alert gives you the following options:
Defines the name for incoming material.
Assigns the characteristics of the incoming materials to the same-named scene materials.
Assigns the characteristics of the scene materials to the same-named incoming materials.
Automatically renames the incoming materials to new names. Uses Material number names based on the next available Material number.
Treats all subsequent incoming Materials with duplicate names the same way you specified for the current object.
When you merge an object that’s linked to a parent object in a source scene, and an object of the same name as the original parent exists in the current scene, the Merge File dialog opens, giving you the option to re-create the same hierarchy.
