Cross-hatching for Unity. Includes post-processing effects for layered hatching, and pigment-based mixing, and demo scenes. Ideal for pen-and-ink, pencil, and other media. Supports Built-In and URP.URP does not work with the RenderGraph, and it needs to be disabled.Gamelogic Fx Cross-Hatching is a stylized rendering toolkit for adding expressive, layered cross-hatching effects to your Unity projects.It provides a family of post-processing effects and supporting shaders that simulate traditional drawing techniques such as engraving, pen-and-ink, and hand-drawn shading — while remaining fully controllable, performant, and pipeline-aware.From classic brightness-driven hatching to advanced convex-hull palette projection and Mixbox-based pigment blending, the package is designed for both artistic exploration and production-ready stylized rendering.See online documentation: Documentation.Features🎨 Post-Processing Cross-HatchingSimple: Brightness-based layered hatching, with CMY mixing ConvexHull Mapping: Custom primary colors with lerp or Mixbox mixing (if installed). Multiple orientation schemes (fixed, uniform, golden, parallel)Hard or soft tonal transitions between hatch layersHatch and background tone control for balanced shadingBase orientation can be constant or controlled with a greyscale texture. 🛠 Editor ToolsDither Pattern Generator: build your own matrices or RGB patterns; export directly as textures.Pattern Texture Generator: create procedural patterns (noise, HSL maps, sine grids, Voronoi, etc.).Gradient Texture Generator: produce ramps, 1D/2D LUTs, and stepped gradients for stylized looks.🎮 Demo ScenesIncluded example scenes for:Built-in Render PipelineUniversal Render Pipeline (URP)These scenes demonstrate recommended setups and serve as a quick starting point.What You Can AchievePen-and-ink illustration styles with layered directional hatchingPencil-style shading, from light sketching to dense tonal buildupMarker and felt-tip looks, with bold directional strokes and controlled layeringPastel-like textures, combining soft tonal transitions with visible stroke structureCrayon-style rendering, emphasizing texture, direction, and imperfect coverage❤️ Why This Package?Gamelogic Fx Cross-Hatching focuses on control, consistency, and correctness.The effects are built on well-structured shader code, clear mathematical models, and editor workflows designed for iteration — making the package suitable for real production use, stylized games, technical art experiments, and advanced rendering pipelines.Supported Unity VersionsUnity 2031.3 and newerSupported Render PipelinesBuilt-in Render Pipeline (complete)Universal Render Pipeline (URP) (⚠️ Does not work with RenderGraph)Cross-Hatching Shaders IncludedSimple hatchConvex hull hatchMixbox convex hull hatchCommon Shaders IncludedAdd TextureAdjust GammaBlend TexturePixelateQuantizeTri-tone MapMinMaxGuassian BlurBox BlurPower MeanConvex Hull MapMixbox Convex Hull MapEditor Tools IncludedDither Pattern GeneratorPattern Texture GeneratorGradient Texture GeneratorDemo ContentScene for Built-inScene for URPSourceFull C# and shader source includedNo DLLs
