Buoys and Small Props

Buoys can work with a single float point. A single point gives clean vertical floating, while the smoothing and normal settings can add gentle tilt.

Single-Point Buoy

Use one child object with WaveFloatPoint, placed near the buoy's center waterline.

Starting values:

Rigidbody Mass: 5 - 50
Buoyancy Strength: 2 - 5
Point Radius: 0.2 - 0.6
Max Point Force: 20 - 80
Water Drag: 0.5 - 1.5
Water Angular Drag: 0.3 - 1
Surface Normal Influence: 0.4 - 0.8
Height Smoothing: 0.05 - 0.2
Normal Smoothing: 0.1 - 0.25
Upright Stability: 0.3 - 1
Upright Damping: 0.5 - 1.5

When to Use More Points

Use 3-4 points when:

  • The buoy is long or rectangular.
  • The object should visibly roll from side to side.
  • One-point motion feels too centered.

For a round buoy, one point is usually enough.

Tips

  • Lower Water Angular Drag for more wobble.
  • Increase Surface Normal Influence for more wave-following tilt.
  • Lower Upright Stability if the buoy stays too upright.
