Face Smoothing Groups brings the speed and familiarity of traditional smoothing group workflows directly into Blender.
If you are tired of manually selecting and marking individual edges as sharp, this add-on allows you to rapidly assign faces to numbered groups. Blender then automatically handles the edge sharpness and vertex normals between differing groups, saving you time and keeping your shading perfectly clean.
Key Features
Familiar Interface: A clean, intuitive panel design that mimics the classic smoothing group systems found in other industry-standard 3D packages.
Rapid Hard-Surface Shading: Quickly block out and shade mechanical parts, weapons, and architectural models without destructive topology changes.
Production-Ready Workflow: Essential for game art pipelines where precise control over vertex normals is critical for flawless high-to-low poly baking in software like Marmoset Toolbag and texturing in Substance Painter.

Quick Select & Clear: Easily select all faces sharing the same smoothing group, or clear assignments on the fly as your mesh evolves.
