With the game's Camera height control on (Gameplay > Advanced Camera), R3 on the board switches between the high and the low camera by writing the opposite of the UseHighCam option. A new switch in SKATER > CAMERA > FIRST PERSON, "First person in the camera cycle" (off by default), makes it high -> low -> first person -> high. - The existing native option hook passes UseHighCam writes to a listener, so the settings code does not depend on the skater code - Low -> first person keeps the low camera and turns first person on; first person -> high turns it off and keeps the high camera - First person is switched through the menu toggle's own action on the next client tick, so the player's first-person settings apply as they are; it only starts on the board, outside Freecam, Noclip and the Park Editor - Saved as FirstPerson.CameraCycle; Reset arm settings keeps it - Add a ctest (first_person_cycle) for the cycle's steps Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
