Polygon Smoothing Groups is a specialized addon for Blender that gives artists full control over polygon smoothing and sharp edges. With this addon, you can easily assign smoothing groups, manage sharp edges and seams, significantly simplifying the process of creating clean and optimized models. Whether you are modeling hard-surface objects or organic forms, Polygon Smoothing Groups helps you define the appearance of your model with precision and efficiency.

Assign smoothing groups with just one click by simply selecting the group number.

If the selection contains polygons without a group, the buttons displaying the group numbers stop showing the numbers

When polygons are reassigned to the same group, shared sharp edges are automatically removed.

Assign random groups to the selected polygons.

The numbers of the random groups never match the group numbers of neighboring polygons.

Select polygons that haven't been assigned to any groups yet.
