Super Scribble - Substance Designer Tool (with Breakdown)

Super Scribble is a powerful, creative, and highly versatile Pixel Processor node for Substance Designer that turns any distribution map into beautiful, continuous scribble-style lines with a single click.

At its core, it traces organic, flowing lines across the input distribution map, creating connected or disconnected strokes that feel hand-drawn yet remain fully procedural and controllable. Whether you want playful kids’ doodles, elegant ornamental flourishes, precise technical hatches, or chaotic abstract noise, Super Scribble delivers it all, and everything in between.

Core features:

Distribution-driven line generation: Lines follow the values in your Distribution map. High values become starting points; the node intelligently connects or separates strokes based on your settings.
Fully tileable or non-tileable output: Toggle seamless tiling with one parameter, perfect for textures that need to repeat endlessly.

Advanced artistic controls:

- Line Amount: Number of segments/strokes (from sparse single lines to dense scribbles)
- Thickness + Variable Thickness map: Uniform or map-driven width variation
- Smoothness: SDF-based edge control for crisp or soft, painterly lines
- Granularize: Adds a gritty, hand-drawn offset to points for that “pencil on paper” feel
- Separation: Decides how strictly the node samples the distribution map (isolates bright areas, creates gaps, etc.)
- Distribution Scale: Zooms into the distribution space for finer or broader patterns
- Chaos: Random displacement of points for organic variation (fully seedable)
- Depth: Automatic linear gradient from first point (black) to last point (white), great for depth maps or flow visualization
- Texture: Overlay any texture with full control (amount, offset, scale, rotation). The texture follows the direction of each individual line
- Background: Instant black or white backdrop

What it can create:

- With the right input maps, Super Scribble can produce an incredible range of styles:
- Kids’ scribbles & doodles: Loose, energetic, playful lines
- Handwritten letters & typography: Elegant script or graffiti tags
- Ornaments & decorative patterns: Victorian filigree, Celtic knots, geometric motifs
- Hatching & cross-hatching: Classic illustration, engraving styles,
- Random noise & organic textures: Perfect for subtle background grain or stylized static

Thanks to the Texture-follows-direction feature and variable thickness, you can turn a simple noise or gradient into everything from delicate pencil sketches to thick oil-paint strokes with embedded patterns.

Super Scribble is the ultimate “creative chaos” tool, procedural enough for production pipelines, expressive enough for pure artistic experimentation. Whether you’re texturing a 3D model, creating 2D illustrations, or building complex material graphs, it gives you instant, high-quality scribble magic with full artistic control.
