Compositing Line Art (CLA)
The Ultimate High-Performance Line Art Solution for Blender5.0
Compositing Line Art (CLA) is a professional-grade toolset for Blender 5.0.0 and above. It is designed to revolutionize how artists generate outlines by moving the heavy lifting into a specialized compositing workflow. Whether you are working on realistic PBR (Physically Based Rendering) projects or stylized NPR (Non-Photorealistic Rendering) scenes, CLA provides a seamless and robust integration.
Unmatched Stability and Performance
Unlike traditional methods such as Freestyle or Grease Pencil Line Art, which often struggle or crash when handling high-density geometry, CLA is built for extreme efficiency.
Massive Scene Support: CLA can stably generate clean line art even in scenes containing tens of millions of polygons.
Superior Reliability: It offers a level of production stability that Freestyle and Grease Pencil simply cannot reach when dealing with heavy assets.
Fast Workflow: By utilizing the CLA Main Group and CLA AOV Group, the add-on automates the technical setup so you can focus on the creative result.
Advanced Material and Alpha Support
One of the most powerful features of CLA is its intelligent handling of complex materials.
Transparency Support: Fully supports materials with opacity/alpha textures, ensuring lines are generated correctly around cutouts like leaves, lace, or decals.
Smart Normal Management: Includes an Ignore Material Normal toggle to keep lines clean.
Material Exceptions: The Use Material Normal list allows you to specify certain materials, such as hair or transparent surfaces, that require unique normal data to render outlines perfectly.
Artistic Style Presets
CLA comes equipped with built-in presets to instantly change the "soul" of your linework.
None: Provides a precise, technical foundation for standard renders.
Pencil: Replicates the soft, grainy texture of traditional graphite sketches.
Mark Pen: Delivers the bold, consistent, and high-contrast look of professional marker drawings.
You can further customize these styles using the Width Jitter and Random Wave controls to add organic, hand-drawn imperfections to your lines.
Compositing Line Art is the definitive choice for artists who demand both the aesthetic flexibility of hand-drawn styles and the industrial stability required for massive, complex 3D scenes.
