Wave Buoyancy

WaveBuoyancy moves Rigidbody objects using float points. Each float point samples the water and applies force at its position.

Setup

1. Add Rigidbody to the floating object root.
2. Add WaveBuoyancy to the same root.
3. Assign a WaveSurface.
4. Add child objects at the intended waterline.
5. Add WaveFloatPoint to each child.
6. Use Auto Assign Float Points.

Fields

Field	Description
Surface	The water surface to sample.
Float Points	Child transforms that apply buoyancy force.
Point Radius	Extra depth tolerance around each point.
Buoyancy Strength	Main upward force multiplier.
Max Point Force	Maximum force per point.
Water Drag	Velocity damping applied while points are underwater.
Water Angular Drag	Rigidbody angular damping while submerged.
Height Smoothing	Smooths sampled water height per float point.
Normal Smoothing	Smooths sampled water normals for softer roll and pitch.
Surface Normal Influence	How much force direction follows the wave normal.
Upright Stability	Torque that keeps the object aligned to the averaged water normal.
Upright Damping	Angular damping applied to the stability torque.
Draw Debug	Draws water sample lines for float points.

Wave Float Point

WaveFloatPoint is a small marker component. It has:

Field	Description
Buoyancy Multiplier	Per-point force multiplier. Useful for heavier bows, sterns, or asymmetric props.
