Velocity-scaling Clang on horizontal Normal Hinges far from Center of Mass during grid rotation
Description:
There is a specific physics calculation bug introduced in recent updates (noticeable since the Prosperity Update). It causes severe, constant "Clang" vibration and audio noise on hinges, depending purely on their distance from the grid's Center of Mass (CoM), their orientation, and angular velocity.
Through rigorous testing, the issue has been isolated to horizontal (transverse) Large Grid Hinges equipped with a Normal Hinge Head. The bug triggers even when the ship is completely stationary in space and only performing rotational maneuvers (turning/pitching/yawing).
The severity of the phantom collision/vibration noise scales directly with distance from the CoM: the further away the hinge is from the ship's Center of Mass (e.g., at the very bow), the more violently it vibrates and clangs during rotation. This is directly tied to the higher tangential velocity vectors experienced by blocks at the edges of a rotating grid.
Toggling Share Inertia Tensor, Hinge Lock, or turning the Hinge completely OFF with 0 Torque does not resolve the issue.
Steps to Reproduce:
- Build a large ship grid with a substantial length.
- Place a standard Hinge at the very front (bow) of the ship, oriented horizontally/transversely.
- Attach a Normal Hinge Head to it.
- Keep the ship stationary in space (linear velocity = 0 m/s) and begin rotating/turning the ship.
- Constant physics collision audio and micro-stutter will immediately trigger from the hinge.
- Move the exact same hinge setup closer to the ship's Center of Mass (CoM) and repeat the rotation. The noise drops significantly or disappears entirely.
Workaround Discovered:
Replacing the Normal Hinge Head with a Medium Hinge Head completely silences the bug and stabilizes the physics, even at extreme distances from the CoM. This indicates a clearance calculation or an inertia tensor scaling flaw unique to the Normal Head's full 1x1x1 hitbox under high angular velocity vectors.
Expected Behavior:
The Normal Hinge Head should maintain physics stability and alignment regardless of its distance from the Center of Mass or the angular velocity generated during grid rotation.
I have the same bug
