Or if you want to preserve tech tree progress when adding MechJeb to all command modules. @PART [*]:HAS[@MODULE[ModuleCommand],!MODULE[MechJebCore]]:Final { MODULE { name = MechJebCore MechJebLocalSettings { MechJebModuleCustomWindowEditor { unlockTechs = flightControl } MechJebModuleSmartASS { unlockTechs = flightControl } MechJebModuleManeuverPlanner { unlockTechs = advFlightControl } MechJebModuleNodeEditor { unlockTechs = advFlightControl } MechJebModuleTranslatron { unlockTechs = advFlightControl } MechJebModuleWarpHelper { unlockTechs = advFlightControl } MechJebModuleAttitudeAdjustment { unlockTechs = advFlightControl } MechJebModuleThrustWindow { unlockTechs = advFlightControl } MechJebModuleRCSBalancerWindow { unlockTechs = advFlightControl } MechJebModuleRoverWindow { unlockTechs = fieldScience } MechJebModuleAscentGuidance { unlockTechs = unmannedTech } MechJebModuleLandingGuidance { unlockTechs = unmannedTech } MechJebModuleSpaceplaneGuidance { unlockTechs = unmannedTech } MechJebModuleDockingGuidance { unlockTechs = advUnmanned } MechJebModuleRendezvousAutopilotWindow { unlockTechs = advUnmanned } MechJebModuleRendezvousGuidance { unlockTechs = advUnmanned } } } } Just for the stupid, how/where does one put in these scripts?
