Unity Cinemachine (Camera System)

Based on Unity 6.3 LTS -- Cinemachine 3.1 package IMPORTANT: Cinemachine 3.x renamed CinemachineVirtualCamera to CinemachineCamera

Core Concepts

Cinemachine procedurally controls the Unity camera at runtime. Compose camera behaviors from reusable components instead of writing custom camera scripts.

Architecture

1. CinemachineBrain -- On Main Camera; drives the Unity Camera from the highest-priority active CinemachineCamera
2. CinemachineCamera -- Lightweight virtual camera describing desired position, rotation, and lens (replaces CinemachineVirtualCamera from v2)
3. Priority System -- Highest-priority enabled CinemachineCamera wins
4. Pipeline Stages -- Body (position), Aim (rotation), Noise stages compute the final camera state
