Group to EditablePoly is a single-button script for 3ds Max by SimonBourgeois. Select one or multiple groups and click the button to produce editable poly (or mesh) objects, one object per group. It supports nested groups, meaning a group within a group. When an editable mesh is present in a group, the resulting object stays an editable mesh, which avoids unwanted edit poly on SketchUp or other CAD-imported models that don't handle edit poly well.
The script has no interface and no options beyond the button and its default icon. Created objects inherit their original group names and layers, and if the original groups were themselves part of a group, the created object remains a member of that parent group. Object pivots are placed at the object base.
Installation follows the usual method: drag and drop the file into the viewport, then go to Customize, Customize User Interface, Toolbar, and find the category "SimonScripts". Version 1.6.2 continues a long line of bug fixes covering instanced objects, multi/sub-object materials, material ID handling, and nested-group scenarios.
