Quad Adder: A New Blender Add-on for Faster Hard-Surface Modeling

Today marks the release of a brand-new add-on from Kushiro: Quad Adder.

What Is Quad Adder?

Quad Adder is a Blender add-on designed to streamline the process of adding clean quad-based geometry directly onto existing meshes. Instead of relying on complex workarounds or manual topology adjustments, Quad Adder focuses on speed, control, and precision—three things that are critical in hard-surface modeling.

The add-on is particularly useful when:

• Building mechanical or industrial forms.
• Adding details to flat or curved surfaces.
• Maintaining clean quad topology for subdivision or game-ready assets.

By reducing repetitive steps, Quad Adder helps artists stay focused on design rather than fighting topology.
