This add-on provides tools for blending, editing, and converting normal maps directly inside Blender. It automates the process of combining two normal maps using mathematically correct blending techniques. Instead of requiring manual node building, the tool generates a dedicated baking scene with a pre-configured setup, keeping the original project files intact.

The tool includes features for one-click conversion between OpenGL and DirectX formats by flipping the green channel. Users can apply overlap masks to blend normals in specific areas or use flat normal masking to clear regions for inserting new details. It also includes controls for adjusting the strength and scale of both the base and added normal maps.
