Cool Magic Shader is an addon from Kito Studio that helps you set up materials, outlines and lights in a Blender project, then switch between realistic and toon render mode. The download package includes the addon file, a complete PDF documentation and a sample Blender project.
The addon lives in the Cool Addons tab of the N-Panel menu, while the magic shader is accessed in the Shader editor when you add a new shader to a material. An Initialization feature imports the toon lights setup and the magic shader node automatically. The shader node carries a common Object base color, toon properties such as shadow intensity, highlight color, highlight intensity and global light color, plus realistic properties for metallic and roughness intensity. A Toggle render mode button moves between the two styles.
In toon render mode, the addon tab lets you adjust the global light color and the outline collection, changing outline color, thickness and opacity. Outline noise factor and seed add a handdraw-like style. It supports Blender 4.2 to 5.1 with Cycles and Eevee, under the GPL license.
