A rebuild builds one segment per key and each needed every key's slot, so a long replay built them once per segment: the game's rebuild is hooked too and the slots built for its first segment are kept for the rest of it (per Behaviour and Subject). The segment player is no longer hooked (it only counted plays for keysmooth status, every frame). The smoothness is a slider beside the switch in the overlay (sent when let go, as each change rebuilds the open replay's camera) and Keyframe smoothness (100, 75, 50, 25%) in the pause menu and Mod Options > Visuals. The startup line logs on the runtime channel.

// Replay keyframes: a smoothness slider for the replay editor's camera. The game plays framing keys
|
||
// (the free camera's among them) as cubic Hermite segments whose tangents are only as smooth as the
|
||
// keys allow: it brakes where a channel turns or slows sharply, and the acceleration jumps at every
|
||
// key. Smoothness σ (replay_curve.h) gives every segment other tangents, up to those of the natural
|
||
// cubic spline through all keys at σ = 1; every key is still met exactly.
|
||
//
|
||
// The game builds the segments whenever a key changes (Engine/Game/Build/<build>/replay_keyframes.h),
|
||
// and each is rewritten as it is built, so that the game's own player plays σ's tangents. A change of
|
||
// setting builds the segments of the session the camera plays again (the game's own rebuild, on the
|
||
// game thread). Only the free camera's Behaviour (the evaluator a key's camera mode plays through) is
|
||
// smoothed; `keysmooth status` counts segments by Behaviour and Subject.
|

// The editor's preview of framing keys (the values it shows at the playhead) is the game's, and at
|

// σ > 0 it plays smoothed keys without its braking.

// Smoothing is off until the player turns it on (`keysmooth on`, or Keyframe smoothing in the menus):

// then σ is the amount (1 unless changed). The settings are kept between game runs (replay_settings.h).
