3D Artist and Sculptor Alan Wyatt has shared a preview demo showcasing an upcoming Line Art Generator created using Blender's Geometry Nodes toolset, which enables one to turn 3D models into a chain of outlines.
According to the developer, the generator is almost fully complete and will be released "within a few days", depending on Alan's schedule. Once available, the generator will be shipped as part of Tradigitalist Toolbag, the artist's incredible collection of Blender-made tools for making traditional-style paintings that also includes four other tools – Blender Live Paint Filter, Blender Illustration Shader, Painter's Color Filter Node, and Painterly Borders Node.
