This plugin will save 3ds Max users a lot of time.
Rapid Tools has made available Octopus 2, a new version of the octal menu system for 3DS Max featuring a fully scriptable and customizable menu system.
The plugin allows using 96 actions under a single hotkey. It features a huge number of predefined octal menus, including Modeling (Chamfer, Inset, Extrude, Bridge, Connect, etc.), selection (ring, step ring, loop, step loop, grow, shrink, etc.), modifiers (Chamfer, Symmetry, Turbosmooth), smoothing groups, and more.
The menu system also has repeat last functionality. What is more, you can change between your menus using your mouse wheel.
