Configuration

Settings live in UserData/MelonPreferences.cfg under [TightBeam].

Setting	Default	What it does
Enabled	true	Master on/off for the whole mod.
FocusModifierKey	LeftAlt	Hold this and scroll the mouse wheel to change focus.
DefaultFocus	0.5	Starting focus. 1 = wide flood, 0 = tight throw.
DefaultIntensity	7	Base brightness (clamped to Min/Max).
MinIntensity / MaxIntensity	1 / 20	Hard floor / ceiling for brightness.
RangeWide / RangeNarrow	8 / 34	Beam range (m) at each focus extreme.
AngleWide / AngleNarrow	66 / 16	Cone angle (deg) at each focus extreme.
ColorHex	#E6F2FF	Beam colour (cool white).
CastShadows	true	Soft shadows so the beam is blocked by walls (turn off on low-end machines).

There are more fine-tuning knobs for the focus feel (sensitivity, easing, flick threshold) in the same section if you want to dial it in.

Co-op

Setting	Default	What it does
RemoteBeams	true	Show the other players’ flashlights as TightBeam cones.
MaxRemoteBeams	4	Most other beams drawn at once, nearest first. 0 turns them off.
RemoteBeamMaxDistance	70	Metres beyond which another player’s beam is not drawn.
RemoteShadowNearest	0	How many of the nearest remote beams may cast shadows. 0 keeps a full lobby smooth.
RemoteSmoothingTau	0.08	Smoothing on another player’s aim. The game replicates their camera about 10x/sec, so without this the cone steps visibly.
RemoteBeamsForUnmoddedPlayers	true	Also draw a cone for players without TightBeam, using your defaults. Turn off to leave their vanilla light alone.
SuppressRemoteVanillaLights	true	Turn off their vanilla flashlight light while their cone is shown, so you never see both.
SyncMyBeam	true	Share your own beam’s shape, colour and effects with the others.

If a big lobby costs you frames, drop MaxRemoteBeams first, then RemoteBeamMaxDistance. Leave RemoteShadowNearest at 0 unless you want a teammate’s beam to cast shadows of its own.

Notes

• On/off is the game’s own flashlight. There is no separate TightBeam toggle key - the beam follows the game’s FlashlightOn state, so it is always in sync and you use your normal flashlight key.
• Brightness is not a player control. It rests at DefaultIntensity (bounded by Min/Max); only mods can change it, via the Modder API.
