Radial Pebbles
A scattered riverbed, cast in filament. Radial Pebbles drops elliptical stones across your surface -- each with its own random rotation and aspect ratio -- creating that perfectly imperfect look of pebbles tumbled smooth by water. The organic randomness makes every seed feel hand-placed, never mechanical.

Parameters
Count- Number of pebbles scattered across the texture. Dense counts create cobblestone paths; sparse counts leave artful negative space.
Coverage- Fill density -- how tightly the pebbles pack together. High coverage tiles the surface like a mosaic floor.
Shape Variation- How much the pebble aspect ratios vary. Low = uniform round stones; high = a mix of circles, ovals, and elongated slivers.
Pebble Size- Scale of each stone. Oversized pebbles overlap into an organic blobby surface.
Blur- Smooths the pebble edges for a more tumbled, water-worn feel.
Seed- Reshuffles every pebble position, rotation, and shape. Each seed is a unique riverbed.
Resolution- Texture resolution in pixels. Higher values preserve the smooth elliptical edges.
Ratio- Aspect ratio of the texture map. Keep near 1.0 for undistorted pebbles.
Depth (mm)- How far each pebble protrudes. Positive = raised stones; negative = carved dimples like a golf ball.
Tile U / Tile V- Tiles the pebble field around (U) and along height (V) for complete surface coverage.
Rotation- Rotates the entire pebble scatter on the UV map.
Width Gain- Thickens extrusion lines over pebble peaks for more pronounced stone edges.
Flow Gain- Adds material flow on pebbles for truly raised, lenticular bumps.
