Idle Lens

When a player stops moving and interacting for a set time, the server switches that player's view to one of 32 built-in camera scenes. Scenes include overhead, below-player and wide reveal framings, and the camera ends each one with a hard cut after it reaches a stationary endpoint. Movement, interaction, scrolling the hotbar or any other detected activity returns the normal player camera at once.

Cinematics start only when the player is able to take one: the mod refuses dead, sleeping, riding, falling, swimming or portal-bound players, and blocks the start near hostile mobs when that option is enabled. It also stops a running cinematic when the server's ticks per second fall below a configurable threshold, and the action bar shows cumulative AFK time. The mod is server-side only and works with unmodified vanilla clients. Files are published for NeoForge 1.21.1 only, and Spark is an optional dependency that gives better low-TPS detection, with a built-in fallback when Spark is absent. The license is the MIT License, and the code is not open source.
