Handy Art Reference Tool is an innovative 3D reference app designed specifically for artists. The core functionality revolves around providing rotatable 3D models of human limbs and skulls, making it easier to draw complex poses without needing live models or awkward self-posing.

The app stands out with its fully adjustable 3-point lighting system that allows users to experiment with realistic shadow effects from different angles. With over 10 included head busts and optional animal skull pack, it serves as a comprehensive reference tool for comic book artists, painters, and casual sketchers alike.

One notable feature is the ability to customize model materials, allowing users to adjust textures, specularity, and colors. This makes Handy particularly useful for digital artists who need precise control over their reference materials while working on detailed artwork or creature designs.

Handy Art Reference Tool offers several distinctive features that cater to various artistic needs. The primary feature set includes multiple rotatable 3D limb models with customizable poses for hands, feet, and skulls, giving artists unprecedented flexibility in their work.

A standout characteristic is the advanced 3-point lighting system. Users can precisely control light sources to create accurate shadow references when drawing heads from different angles. This feature proves invaluable for portrait artists and comic illustrators seeking realistic lighting effects.

The recently added material editing capabilities allow artists to modify model properties extensively. They can disable textures, adjust specularity levels, or apply color tints to models, creating customized reference materials that perfectly match their artistic requirements.
