Gamelogic Fx Cross-hatching

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.

Features

🧪 Experimental: Supports AI Skills. 🧪

🎨 Post-Processing Cross-Hatching

• Simple: 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 layers
• Hatch and background tone control for balanced shading
• Base orientation can be constant or controlled with a greyscale texture.

🛠 Editor Tools

• Dither 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 Scenes

Included example scenes for:

• Built-in Render Pipeline
• Universal Render Pipeline (URP)

These scenes demonstrate recommended setups and serve as a quick starting point.

What You Can Achieve

• Pen-and-ink illustration styles with layered directional hatching
• Pencil-style shading, from light sketching to dense tonal buildup
• Marker and felt-tip looks, with bold directional strokes and controlled layering
• Pastel-like textures, combining soft tonal transitions with visible stroke structure
• Crayon-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.
