Hey guys, So, I don`t know if this will help much, but I was trying to get the effects in for the ARM-patch Engines, and I also ran into that "only 2 effects at a time" thing. The thing is, the game somehow doesn`t recognize effects that are numbered higher than 2. I tried to add the effects to the cluster engine, and it would only show me the 2 effects that have their name end in 1 and 2. So I tried around a bit with the naming, and the only thing that ever loads are the effects named "PreLaunchEffectEngine1" and "PreLaunchEffectEngine2". So I tried using those twice each. Result: In the VAB the effect works as it should, on all 4 nozzles: But on the launchpad it adds the effects with the same name together to one, adding up all the parameters: So, I guess the game really doesn`t recognize the effects if they aren`t numbered 1 or 2, why ever, I`m no expert of any sorts on this... But I did get it for the other big Engine: @PART[Size3AdvancedEngine] { MODEL { model = NASAmission/Parts/Size3AdvancedEngine/Size3AdvancedEngine scale = 1.0, 1.0, 1.0 } MODEL { model = CoolRockets/FX/cryo-1m/model position = 0.0, -1.0, 0.0 scale = 1, 1, 1 rotation = 0, 0, 0 parent = thrustTransform } MODULE { name = KM_PreLaunchEffect effectName = PreLaunchEffectEngine1 checkBottomNode = true width = 0.5 height = 20 xOffset = 0 yOffset = -0.6 zOffset = 0.1 numP = 40 speedX = 0 speedY = -0.2 speedZ = 0 size = 1.8 } } And the big liquid boosters too, but of course without the exhausts, since it won`t do more than 2 effects: @PART[Size2LFB] { MODEL { model = NASAmission/Parts/Size2LFB/Size2LFB scale = 1.0, 1.0, 1.0 } MODEL { model = CoolRockets/FX/cryo-1m/model position = 0.0, -1.0, 0.0 scale = 1.0, 1.0, 1.0 rotation = 0, 0, 0 parent = thrustTransform } MODULE { name = KM_PreLaunchEffect effectName = PreLaunchEffectEngine1 checkBottomNode = false width = 0.1 height = 10 xOffset = 0 yOffset = -3 zOffset = 1.2 numP = 25 speedX = 0 speedY = -0.2 speedZ = 0 size = 1.5 } MODULE { name = KM_PreLaunchEffect effectName = PreLaunchEffectEngine2 checkBottomNode = false width = 0.1 height = 10 xOffset = 0 yOffset = -3 zOffset = -1.2 numP = 25 speedX = 0 speedY = -0.2 speedZ = 0 size = 1.5 } } I hope someone figures out how to get more than 2 effects to work.
