Kushiro Dirty Edge (AO) is a procedural shader for Blender's Cycles engine that generates edge wear and ambient occlusion effects. The shader uses the Cycles Bevel node to detect edges, which provides a different result compared to the standard pointiness node, and combines this with ambient occlusion data.

The shader node group includes customizable settings for fine-tuning the look of the edges and dirt. A second version, Type 2, is included, offering an updated noise pattern design and additional configuration options. A sample 3D model is provided within the file for testing the material.
