Hello ksp Forums. I am having some trouble with my engine its config is based off the lv-909 engine and the fx is always on not just when the engine is on. Any suggestions. This is my config. PART { // Kerbal Space Program - Part Config // LV-T453 Liquid Fuel Engine // // --- general parameters --- name = liquidEngine32 module = Part author = Mrbrownce // --- asset parameters --- mesh = Model2.mu scale = 0.01 // --- FX definitions --- fx_exhaustFlame_blue_small = 0.0, -21.0, 0.0, 0.0, 1.0, 0.0, running fx_exhaustLight_blue = 0.0, -21.0, 0.0, 0.0, 0.0, 1.0, running fx_smokeTrail_light = 0.0, -21.0, 0.0, 0.0, 1.0, 0.0, running // --- Sound FX definition --- sound_vent_medium = engage sound_rocket_hard = running sound_vent_soft = disengage sound_explosion_low = flameout // --- editor parameters --- TechRequired = survivability entryCost = 1600 cost = 750 category = Propulsion subcategory = 0 title = LV-91109 Liquid Fuel Engine manufacturer = Jebediah Kerman's Junkyard and Spaceship Parts Co. description = The 909 model was initially received with some skepticism by spacecraft engineers, as it defied the long-standing convention that "More Power!" is always better. Despite this, the 909 series has found its place in the spacecraft construction world, being particularly useful as a final stage and landing engine. // attachment rules: stack, srfAttach, allowStack, allowSrfAttach, allowCollision attachRules = 1,0,1,0,0 // --- standard part parameters --- mass = 0.5 dragModelType = default maximum_drag = 0.2 minimum_drag = 0.2 angularDrag = 2 crashTolerance = 7 maxTemp = 3600 NODE { name = top transform = top } MODULE { name = ModuleEngines thrustVectorTransformName = ThrustTransform exhaustDamage = True ignitionThreshold = 0.1 minThrust = 0 maxThrust = 50 heatProduction = 300 fxOffset = 0, 0, 0.21 PROPELLANT { name = LiquidFuel ratio = 0.9 DrawGauge = True } PROPELLANT { name = Oxidizer ratio = 1.1 } atmosphereCurve { key = 0 390 key = 1 300 } } MODULE { name = ModuleGimbal gimbalTransformName = thrustTransform gimbalRange = 0.5 } MODULE { name = ModuleAnimateHeat ThermalAnim = HeatAnimatioEmissiveLiquidEngine3 } MODULE { name = ModuleJettison jettisonName = fairing bottomNodeName = bottom isFairing = True jettisonedObjectMass = 0.1 jettisonForce = 5 jettisonDirection = 0 0 1 } } Thanks!
