Spiral Seeds
Fibonacci would be proud. Spiral Seeds plants Archimedean spirals across your surface -- those elegant, mathematically perfect curves you see in sunflower heads, nautilus shells, and galaxy arms. Each spiral winds outward from its center, and when multiple spirals overlap, the interference creates hypnotic, organic patterns.

Parameters
Count- Number of spiral centers scattered across the texture. Dense spirals interlock like clockwork; sparse ones stand alone.
Fill- Density of spiral elements. Lower fill spreads them out; higher fill weaves a tighter spiral tapestry.
Tightness- Number of turns per spiral. Low = loose, open arms; high = tightly wound springs that pack detail into small spaces.
Spiral Size- Radius of each spiral element. Large spirals dominate; small ones feel like scattered fossilized ammonites.
Blur- Softens the spiral arms for a smoother, less mechanical curve.
Seed- Repositions and re-rotates all spirals. Each seed grows a different garden of swirls.
Resolution- Texture resolution in pixels. Tight spirals need high resolution to keep their curves smooth.
Ratio- Aspect ratio of the texture. Keep near 1.0 so spirals stay round rather than elliptical.
Depth (mm)- How far spiral arms push outward. Negative values carve the spirals as grooves -- like scroll engraving.
Tile U / Tile V- Tiles the spiral field around (U) and along height (V) for seamless coverage.
Rotation- Rotates the spiral field on the UV map.
Width Gain- Varies extrusion width along the spiral arms for a tapered, calligraphic stroke effect.
Flow Gain- Extra material on spiral crests for raised, relief-carved swirls.
