Select Multiple Instances

The script has a bug I’m fixing. I’ll fix it soon!

Problem I’m solving

With native max, you can do Edit > Select Instances to select all instances of an object. However, this option is not available for multiple objects.


This script helps you quickly select multiple instances even instance objects within groups.


  1. Simply just drag the script to the viewport to install.
  2. Right-click on the toolbar > Customize…
  3. Choose the tab ‘Toolbars’
  4. In the Category: dropdown, select ‘ManniiCode’
  5. Drag the script to the toolbar where ever you want!
