Mapping Operations is a 3ds Max script for applying relational functions across matched objects. It relates one set of user-selected objects to another using a mapping text file, and its operations include Align, Bind, Link, Mirror and Constrain. The mapping text file is generated automatically from two separate source and target text files, each listing the required selected objects in the correct order.
Before creating the mapping file, you can open those source and target lists in a text editor such as Notepad++ and reorder them so the entries line up. Once a mapping file is set up for a collection of related objects, you can reload it later to reapply the operations without rebuilding the pairing.
Version 1.2 converted the dialog into a floater with rollouts that separate creating a mapping from running the operations, with the floater position persisting between Max sessions. This release also added the Mirror operation, replaced the Bake button with an optional Align checkbox, and improved error handling for missing mapped objects.
