Mallet: UV Aligner is an addon that provides a dedicated panel in the 3D Viewport sidebar for precise UV mapping adjustments. It includes a World Align feature that seamlessly adjusts textures based on world coordinates, ensuring consistent scaling and positioning across multiple objects or specific faces regardless of their individual transforms. This provides an alternative to the default Cube Project method for handling angles and rotations.

The toolset offers justification options to shift UVs to the top, bottom, left, or right edges based on the closest vertex. Additional features include a Fill function to scale UV maps to cover the entire UV space with adjustable repetition, as well as basic transform tools for moving, scaling, and rotating UVs from specific centers or edges. The addon supports both Imperial and Metric system customizations for precise adjustments.
