Scene Explorer Delete Extension
This script allows deleting selected nodes and layers in the Scene Explorer. The default delete option of 3ds Max only deletes empty layers and nodes without childs. With this tool, deleting a selected parent node or layer implies deleting all its children hierarchy.
When you drag this script into the viewport of Max, it’s added to the “Barreira” category of the Customize User Interface panel. Then, you can create a button to execute the script easily.
