Unity Cinemachine
By Unity Technologies
Unity camera tooling for target following, composition, blends and cuts; useful for third-person/2D cameras and cutscenes configured in the Inspector.
Install Cinemachine with Package Manager. This workflow follows Cinemachine 3.1 and requires Unity 2022.3 LTS or newer. Create a Follow Camera from GameObject > Cinemachine > Targeted Cameras, verify Cinemachine Brain on the Unity Camera, assign Tracking Target, then adjust offset, damping and composition. Read the upgrade guide before migrating a 2.x project because 3.x contains breaking changes.
