In Ship Setup, add Bridge Equipment, then select the type Exhaust. Choose Engine1, Engine2 or Generator and set its position, rotation and output values. The editor's generator selector starts at 1 for convenience. JSON and the Blueprint Generator Index start at 0. The editor shows an outlet placement marker, not a live smoke preview. Save JSON and reload the ship to apply your changes. Creator-locked protected ships cannot have their settings edited; configure the original FBX-based version and export a new release. Merge these entries into the existing `bridgeEquipment` array. Keep other entries; do not create a second array with the same key. Every entry needs a unique `id`. ```json code { "bridgeEquipment": [ { "id": "main_engine_exhaust", "type": "Exhaust", "action": "Engine1", "positionCm": [-500, -100, 800], "rotationDeg": [0, 0, 0], "exhaustEnabled": true, "exhaustAutoRPM": true, "exhaustIdleRate": 12, "exhaustFullRate": 70, "exhaustIdleSpeed": 40, "exhaustFullSpeed": 120, "exhaustScale": 1 }, { "id": "second_engine_exhaust", "type": "Exhaust", "action": "Engine2", "positionCm": [-500, 100, 800], "rotationDeg": [0, 0, 0], "exhaustIdleRate": 12, "exhaustFullRate": 70, "exhaustScale": 1 }, { "id": "generator_1_exhaust", "type": "Exhaust", "action": "Generator", "generatorIndex": 0, "positionCm": [-700, 0, 900], "rotationDeg": [0, 0, 0], "exhaustAutoRPM": true, "exhaustIdleRate": 3, "exhaustFullRate": 15, "exhaustIdleSpeed": 20, "exhaustFullSpeed": 60, "exhaustScale": 0.6 } ] } Positions are ship-local centimetres: +X forward, +Y starboard, +Z up. Rotation order is `[pitch, yaw, roll]`, in degrees. Position values above are examples, not automatic funnel detection. | Field | Default | Meaning / range | | --- | --- | --- | | `action` | `Engine1` | `Engine1`, `Engine2` or `Generator` | | `generatorIndex` | `0` | Generator index, 0–63 | | `exhaustEnabled` | `true` | Enables this outlet | | `exhaustAutoRPM` | `true` | Uses the assigned machine's RPM range | | `exhaustIdleRPM` | `700` | Manual lower RPM, 0–100000 | | `exhaustFullRPM` | `4200` | Manual upper RPM, 1–100000; must exceed the lower value | | `exhaustIdleRate` | `12` | Lower output, 0–2000 particles/second | | `exhaustFullRate` | `70` | Upper output, 0–2000 particles/second | | `exhaustIdleSpeed` | `40` | Lower exit speed, 0–10000 cm/s | | `exhaustFullSpeed` | `120` | Upper exit speed, 0–10000 cm/s | | `exhaustScale` | `1` | Smoke sprite size multiplier, 0.01–100 | Currently the shared `bridgeEquipment` limit of 64 entries includes exhaust outlets, instruments, lights, antennas and controls.
