Anisotropic Kuwahara Oil Paint - Stylized Post-Process Material is a complete solution for achieving real-time, hand-painted visuals such as classic oil paintings, watercolors, and comics in Unreal Engine.
It includes a powerful master post-process material utilizing optimized HLSL custom nodes to ensure high performance. Key visual features include a Smoothed Structure Tensor that calculates the directional flow of brush strokes, and an Anisotropic Kuwahara filter that dynamically aligns those strokes to the contours of your 3D models. Additionally, the system features a Hue-Preserving Posterization method based on luminance. This ensures that only the lighting is divided into hard steps, keeping the original colors clean and preventing unwanted hue-shifting.
The system is designed for a simple workflow using the included 10 ready-to-use Material Instances, covering presets like Classic Oil, Oil Heavy Strokes, Sketch Monochrome, and Vibrant Cel Shaded. To maintain high frame rates, the material integrates essential performance controls such as a customizable Sample Step Size and Static Switches, ensuring that optional features like the integrated Outline effect are highly optimized.
