Easy Blend Normals is a Geometry Nodes add-on for Blender that blends normals between two objects in a single click. Select two objects — the active one acts as the main, the other as the target — then click the blend button, and normals are blended automatically for smooth shading. Its smart linking auto-detects which object is active and which is the target.
The add-on is aimed at hard-surface work. It can fix shading after boolean operations, make separate kitbash parts look like one solid mesh, and blend normals across panels, plates, and mechanical seams. The goal is to speed up hard-surface workflows without manual normal transfers.
Built on Geometry Nodes, the setup is non-destructive and fully editable, so you can tweak the result at any time. It has no dependencies and is ready for Blender 4.5. It works best when object scales are applied first (Ctrl+A → Scale). The render engines listed are Cycles and Eevee, and the add-on is released under the GPL license.
