Simple Sketch Pro is an add-on that simplifies the creation of line art and non-photorealistic illustrations in Blender. It includes one-click presets for styles such as transparent lines, clay with ambient occlusion, sketch style, and comic looks. Users can toggle between these presets and their existing scene setups.

The tool provides controls for adjusting line weights and colors, alongside an option to calculate lines in screen space to maintain consistent thickness regardless of perspective. Additionally, it allows for per-object overrides, letting users assign specific material and line art settings to individual objects within a scene.
