MissileCamera (Nuclear Option Mod)

---

Critical warnings

Important

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

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

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 while it guides toward the target.
• Tactical HUD overlay: Telemetry (SPD, ALT, RNG), horizon reticle, salvo info, and target markers drawn on the live feed.
• 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.
  • 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). Keybinds are fixed in code (not in Configuration Manager).

Keybind	Unity KeyCode	Action
Right Alt + /	RightAlt + Slash	Next missile (newer; wraps 6/6 → 1/6)
Right Alt + ,	RightAlt + Comma	Previous missile (older; wraps 1/6 → 6/6)
Right Alt + ;	RightAlt + Semicolon	Zoom in (narrower FOV)
Right Alt + .	RightAlt + Period	Zoom out (wider FOV)
Right Shift + .	RightShift + Period	Reset zoom offset to 0.0

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: each zoom change shows the current offset for 0.5 s above feed center. Zoom step/limits: MissileCameraControls in Configuration Manager.
