I am generating a monopropellant engine as a learning exercise. I have been able to create a model in blender, import it to unity, and export it out via part tools to the GameData folder. The part loads and attaches as expected. Everything appears to be working except that the engine effects do not show and the engine seems not to generate any thrust even though it uses the monopropellant. I have beat my head on this and have absolutely no idea why. Any suggestions would be appreciated. here's the config PART { name = FI_monoEngine module = Part author = Fuzzi mesh = model.mu scale = 1 rescaleFactor = 1.25 node_attach = 0.0, 0.15, -0.0666, 0.0, 0.0, 0.0 fx_exhaustFlame_yellow_tiny = 0.0, 0, 0, 0.0, 1.0, 0.0, running fx_exhaustLight_yellow = 0.0, 0, 0.0, 0.0, 0.0, 1.0, running sound_vent_medium = engage sound_rocket_mini = running sound_vent_soft = disengage sound_explosion_low = flameout cost = 340 category = Control subcategory = 0 title = FI-10 manufacturer = Fuzzi description = This tiny engine runs on monopropellent and is perfect for small probes. attachRules = 0,1,0,1,0 mass = 0.2 dragModelType = default maximum_drag = 0.1 minimum_drag = 0.1 angularDrag = 0.1 crashTolerance = 7 breakingForce = 50 breakingTorque = 100 maxTemp = 1800 MODULE { name = ModuleEngines thrustVectorTransformName = thrustTransform exhaustDamage = True ignitionThreshold = 0.1 minThrust = 0 maxThrust = 10 heatProduction = 10 fxOffset = 0, 0, 0.01 PROPELLANT { name = MonoPropellant ratio = 1 DrawGauge = True } atmosphereCurve { key = 0 290 key = 1 100 } } MODULE { name = ModuleGimbal gimbalTransformName = thrustTransform gimbalRange = 1 useGimbalResponseSpeed = true GimbalResponseSpeed = 0.1 } }
