Adjust Physics & Mass Properly

  • Select your kayak mesh and ensure these settings:
    Simulate Physics: ON
    Enable Gravity: ON
    • Mass: Set realistic mass (e.g., 30-50 kg for a kayak)
    • Linear Damping: Set between 1.0 - 3.0
    • Angular Damping: Set between 2.0 - 5.0

Double-check your kayak’s collision shape
Incorrect collision** can cause it to ignore buoyancy and sink

Quick Buoyancy Testing

  • To quickly identify the issue, temporarily create a simple cube with:
    • Buoyancy Component
    • Properly positioned pontoons
    • Low mass (10 kg)
  • Test if this cube floats properly.
    • If it floats, your issue is with the kayak mesh or pontoon setup.
    • If it sinks, re-check the Water Body settings (collision, buoyancy).
