MissileCamera (Nuclear Option Mod)

Nuclear Option BepInEx 5 Version License: MIT

Critical warnings

Important

BepInEx 5 (x64) required - install BepInEx before this mod.

Note

Fullscreen never touches the cockpit camera - seeker video is a dedicated RenderTexture on a UI RawImage. See Fullscreen/CAMERA_SAFETY.md in the source tree.

Warning

  • Third-party aircraft and MFD mods may break layout - custom TargetScreenUI / tactical overlays can conflict; set DisplayMode=skip in Configuration Manager or disable conflicting MFD mods.

Tip

Configuration Manager recommended - in-game UI for com.at747.missilecamera.bepinex.cfg. After game updates, delete BepInEx\cache\harmony_interop_cache.dat if patches behave oddly.

BepInEx 5 plugin for the flight sim Nuclear Option that adds a live seeker-eye view (Missile Nose Cam) and a tactical HUD overlay directly onto your cockpit MFD Target display.

Plugin GUID: com.at747.missilecamera.bepinex

Table of contents

Features

  • MFD split-screen UI: Splits the wide tactical MFD (Target view) into zones and embeds the missile feed in the weapons panel area.
  • Seeker cam (missile nose cam): Renders a live RawImage feed from your latest player-owned in-flight missile. No selected target required — dumb-fire / no-lock launches still open the MFD feed. On destruction, a brief TV-static burst plays before the panel closes.
  • Fullscreen feed: RightAlt+F — dedicated seeker RenderTexture on a fullscreen RawImage (same as MFD). Never hijacks vanilla CameraStateManager / cockpit camera. First enter per mission plays a ~3.5s boot (tile assemble → symbol cal → hex/value drums + diagnostics). FLIR chrome overlay; CombatHUD unit markers only.
  • Fullscreen zoom / filters: mouse wheel optical zoom up to 50× (MMB reset); J cycles vision modes (Color / NVG / WhiteHot / BlackHot / Contour±). MFD keeps keyboard zoom + auto IR when dark.
  • Fullscreen FLIR HUD: green sensor chrome with live — MSL — / — TGT — telemetry, scrolling compass, dials; vanilla CombatHUD target markers — fullscreen only. MFD keeps the classic S/A/R corner HUD.
  • Classic MFD HUD: S/A/R corners + salvo (1.30.1 style).
  • Post-FX: optional scanlines / motion blur / chromatic / bloom (MissileCameraEffects) — inactive with a startup warning if shaders are missing from the embedded bundle.
  • Aircraft mini-cam: optional second feed (MissileCameraAircraftCam, default off). No-op when DisplayMode=skip.
  • Auto B/W IR (WhiteHot): When dark at the missile — low GetDaylightFactor (night / under thick clouds) or very low GetAmbientLight — the feed switches to black-and-white IR. Not a fixed clock window. Disable with InfraredAutoEnabled=false.
  • Manual feed controls: Cycle in-flight owned missiles and adjust camera zoom while the MFD overlay is active (see Controls below).
  • Per-aircraft layout (DisplayMode=auto):
    • Dedicated split (e.g. KR-67): wide target cam on the left, missile panel on the right.
    • VT-7 Vagrant: MissileCamera replaces the right-column NOZZLE + ENGINE block (weapons silhouette kept).
    • Small tac overlay (e.g. Cricket): mod skipped — vanilla tactical MFD unchanged.
  • Mission-only bootstrap: Harmony patches and the feed driver attach on the first mission scene, not in the main menu.

Requirements

  • Nuclear Option (Steam).
  • BepInEx 5 (x64) in the game root (BepInEx\core\ must exist for build reference paths).
  • Configuration Manager (recommended) — in-game UI for plugin settings.

Player installation

  1. Install BepInEx 5 for Nuclear Option.

  2. Install Configuration Manager (recommended).

  3. Copy into:

    Nuclear Option\BepInEx\plugins\MissileCamera\
    • MissileCamera.dll

  4. Settings are stored in BepInEx\config\com.at747.missilecamera.bepinex.cfg (auto-created on first run). Edit in-game via Configuration Manager, or edit the .cfg file while the game is closed.

  5. Do not rename the plugin folder or install duplicate copies under different names.

  6. See release/v0.27.1/INSTALL.txt or GitHub Releases for a checklist.

Controls & keybinds

Active only while the missile feed overlay is on and you have player-owned in-flight missiles. US English keyboard layout (Right Alt may act as AltGr on some EU keyboards). Every keybind is a Configuration Manager KeyboardShortcut under MissileCameraControls / MissileCameraFullscreen / MissileCameraAircraftCam.

Keybind Default Action
NextMissile Right Alt + / Next missile (newer; wraps)
PreviousMissile Right Alt + , Previous missile (older; wraps)
ZoomIn Right Alt + ; MFD zoom in (narrower FOV)
ZoomOut Right Alt + . MFD zoom out (wider FOV)
ResetZoom Right Shift + . MFD reset zoom offset to 0.0
Mouse wheel — Fullscreen only: optical zoom 1×…50×
ZoomResetKey Middle mouse Fullscreen only: reset magnification to 1×
Toggle K Fullscreen missile camera toggle
VisionCycle J Fullscreen vision cycle
CycleMode Right Alt + V Aircraft mini-cam mode cycle (when enabled)

Vision cycle (fullscreen): Color → NightVision → WhiteHot → BlackHot → WhiteContour → BlackContour. NightVision uses a local feed Volume only — never toggles stock cockpit NVG.

Sticky selection: after Next/Prev the camera stays on your chosen missile when new ones launch. If it is destroyed, the feed falls back to the newest remaining missile.

Zoom HUD (MFD): each zoom change shows the current offset for 0.5 s above feed center. Fullscreen FLIR shows MAG xN from optical magnification.

Configuration (BepInEx Configuration Manager)

Player-facing settings only (Config/MissileCameraBepInConfig.cs). Advanced tuning (layout geometry, IR picture math, HUD colors, zoom feel, FX intensities) is hardcoded in the *Config classes. Use Configuration Manager in-game, or edit:

BepInEx\config\com.at747.missilecamera.bepinex.cfg

Tip

After this config slim, delete the old .cfg once (game closed) if orphaned keys clutter Configuration Manager — defaults recreate cleanly. Fullscreen toggle is now Toggle = K (no Right Alt).
