This is a perfect job for the State system. 1. Start the game and tweak a camera position that's off to the left side. 2. In the Preset foldout, click "Save Tweaks" to save this position tweak to a new preset text file. 3. See the "State Manager" chapter in the manual for instructions on how to bind the preset to a "LeanLeft" state and in turn bind the state to a key via script. 4. Repeat for "LeanRight".
