Selection Toolbox is a script for 3ds Max, developed by JokerMartini, that gathers several selection methods into a single toolset. It works with 3ds Max 2021, and the tracked release is version 1.0, last updated in September 2022.
The Quick Select commands select objects visible in the current viewport, objects not in view, objects with a material, objects with no material, and instances of the current selection. Dialogs list the unique Object Classes, Object Super Classes, Modifier Classes, Modifier Names, Material Classes and Material Names found in the scene, so you can pick one or more entries and select every matching object.
Wirecolor Select picks objects whose wirecolor falls within a tolerance of the selected object's wirecolors, with a 0% to 100% value controlling the hue range. Find and Select runs a string search by object, class, modifier or material name, with a regex or wildcard toggle and an option to limit the search to the current selection.
