Developed by Cogumelo Softworks.

About Toonkit For Cycles
Toonkit For Cycles provides OSL‑based shader nodes that integrate directly into the Cycles node system and Blender’s viewport. All node outputs are colors, allowing unrestricted mixing of shading, shadow, and specular components. The add‑on includes Face Paint tools that use vertex colors in Edit Mode for cartoon‑style painting, and two ray‑trace line rendering nodes with controls for Normal, Depth, Object ID, Silhouette, and Vertex Color influences. Production‑quality images typically converge with 4 to 32 samples. Version 1.7 adds support for Blender 4.x, reworks Face Paint around Blender Color Attributes, and makes the download file act as its own installer. It is suited for anime, technical, architectural visualization, engineering, and expressive art projects.
