Copy Sets allows you to copy existing object sets and paste them into a new scene.
A new and free script for Autodesk Maya lets you copy and paste object sets between scenes which is helpful for rigging and scene constancy and management. Copy Sets, from Orkhan Ashrafov will let you copy object sets in a structure and recreate the same set hierarchy in a new scene with a simple paste.
The python script, which is available for free, is simple to install and run. Just place the file in the default “scripts” folder. Go to Maya and run these two lines from a python tab: import oa_copySets, oa_copySets.UI(). Now you can have the same sets in multiple files with a nice and clean outliner.
