KSP2 v0.1.4.0 Patch Notes

Bug Fixes


  • Fixed: Center of Thrust, Center of Mass and Center of Pressure markers appear when there's no vessel in the VAB

Flight & Map

  • Added input binding for toggling freecam in flight

  • Added NavBall texture color changes based on velocity state

  • Improved orbits decaying when vessels are not applying any thrust

  • Fixed: airbrakes respond to roll inputs

  • Fixed: camera orientation flips 180 degrees after switching to flight from map

  • Fixed: Kerbals eject with extra velocity when EVA'd from Grumble Seats while in space flight

  • Fixed: dates don't start on year 1 day 1

  • Fixed: activate/deactivate action button for engines gets out of sync

  • Fixed: alternators produce power when engines are off

  • Fixed: animated engine gimbal forces are incorrect after reverting

  • Fixed: animated gimbals don't function when offscreen (when in map or offscreen during flight)

  • Fixed: AP and PE markers of inactive vehicle in orbit stay on screen after switching focus to a landed vehicle within the Tracking Station

  • Fixed: active vessel can be controlled while in the Tracking Station"

  • Fixed: camera zooms in and out when scrolling in some flight apps

  • Fixed: errors generated when launching a vessel with a fairing

  • Fixed: hibernate In Time Warp doesn't work properly for probes

  • Fixed: Mouse look does not stay active when pressing Tab in flight

  • Fixed: probe cores stop consuming electricity after being decoupled

  • Fixed: RCS blocks don't work in fine control mode

  • Fixed: RCS thrusters remain on when switching away from a vessel

  • Fixed: SAS and throttle sometimes reset when decoupling stages

  • Fixed: SAS mode buttons don't always register clicks

  • Fixed: Timewarp overshoots when crossing SOI boundary, causing orbit to change

FX and Audio

  • Adjusted timing of voiceover when reaching a maneuver in the burn timer

  • Fixed: audio stopping under some circumstances

  • Fixed: sounds based on time of day don't play correctly at KSC

  • Fixed: vessel audio is not heard when throttling or staging the vessel while in map mode


  • Integrated: Localized strings for save gameplay menu


  • Fixed: LoadByLabel not properly respecting assets in addressables in mod asset bundles. Labelled addressables should load properly now


  • Added LODs to some KSC buildings

  • Added LODs to spotlight shadows at KSC

  • Cleaned up code and UI to improve performance of some windows

  • Improved performance when hovering over items in the parts picker UI

  • Improved UI performance when adding or removing stages in the VAB

  • Improved VAB framerate by optimizing part bounds calculations

  • Massively improved speed of PAM deployment/closure

  • Optimized code in the sonic boom system preventing unnecessary calls

  • Optimized terrain shader by removing expensive and infrequently-used features

  • Optimized undo and redo actions in the VAB to reduce update delays

Parts and Stock Vessels

  • Adjusted colliders for all landing gear parts so they are more accurately selectable/highlightable

  • Fixed: LY-60 landing gear sometimes flips when extended

  • Fixed: Rovemax M1 twitches back and forth at the suspension when off the ground in Flight.

  • Increased fairing maximum length for AE-FF000, AE-FF125, AE-FF250, AE-FF375 and AE-FF500 parts

  • Updated drag cube for the "HS-I Deluxe Inflatable Heat Shield" so that it properly changes when deployed and retracted

  • Updated the side count of the RF-AD-L 800 fuel tank to better match like-sized parts

  • Updated the side count of the RS-AD 800 fuel tank to better match like-sized parts

Saving and Loading

  • Fixed: error generated and failure to load when attempting to load a game with a crash-landed vessel

  • Fixed: error spam while loading a game with a vessel orbiting Kerbol


  • Fixed: First Time User Experience confuses map view for tracking station view

  • Fixed: the player loses keyboard and camera control when pausing and resuming a tutorial mission while in map mode in the Training Center

Known Issues

Orbital Decay

  • Improvements have been made to address the issue and we continue to work on eliminating it completely.

Performance Degradation

While we have seen improved performance in many ways as noted in the Optimization section above, some players may see issues on GPU bound setups while in orbit around Kerbin or on the surface of other planets.

We are working to resolve this issue and if you see any change in your performance, please fill out a bug report through the link below.
