Unity Cinemachine Jittering Issue

1. About Cinemachine Method Update

Main symptom

• Due to Cinemachine camera damping, jittering occurs when a character or airship moves quickly.

Character Rigidbody settings

Cinemachine Brain (Main Camera)

Cause analysis

• Rigidbody.Interpolate handles CCD-related interpolation for physics-based moving characters.
  When Cinemachine Camera follows/looks at that player, the Transform value updated through its Update Method
  and the Transform value processed by damping interpolation can diverge.

Solution

1. Disable Rigidbody -> Interpolate for physics-based player movement.
2. Handle movement code (rigidbody.velocity, rigidbody.AddForce(), etc.) in FixedUpdate.
3. Set Cinemachine Camera Update Method and Blend Update Method to Fixed Update.
4. Disable Virtual Camera -> Inherit Position.
