Quick Selection is a 3ds Max utility built around object selection and management. It provides selection by category, selection by stored objects, selection by selection sets that stay independent of any Max file, and selection by pathname literals stored in a text file. An online guide is available in the links section on the developer's page.
Version 1.1 changes how stored selections are handled. Store Selection now writes object names to an INI data file, the same approach used for selection sets, so selections persist. The update also adds the ability to rename a selection set item and to sort the selection sets list, along with a thin bar button that opens the INI data file for browsing or editing.
This release also includes internal code refactoring and further UI tweaks. Quick Selection is compatible with 3ds Max versions 2019 through 2024, and this catalog lists it as free.
