PaintFilter is an add-on that integrates a custom compositor group node into Blender to produce artistic and stylized post-processing effects. Designed for non-photorealistic, painted, or toon-style renders, the filter leverages built-in features like Kuwahara and Diamond Sharpen to manipulate the final image.

The tool streamlines the compositing workflow by providing an N-Panel interface for one-click deployment. Users can automatically inject and wire the filter between their render layers and composite outputs without manually managing the node tree. Once applied, all node parameters and sliders can be adjusted directly from the 3D viewport panel.
