TweakScale lets you change the size of a part. Not just that, but it will figure out how much fuel is in the resized part. And if it's an engine, it will become more powerful by scaling it bigger, or weaker by scaling it smaller.

Version for Kerbal Space Program 1.5.1

Released on 2018-10-28

  • 2018-1027: (Lisias) for KSP 1.4.1+; 1.5
    • KSP 1.5 support certified.
    • Reverting some misunderstood versioning.
    • Moving the repository to the Official Headquarters
    • Some performance (and type safety) enhancements
    • Fixes on the MX-3L Hermes (NFT) as proposed by NachtRaveVL
    • Fixed an issue when Making History is present.
      • With additional failsafe measure
    • Bumping Release to assume official maintenance and mark the URL change.


Version v2.3.12 for Kerbal Space Program 1.4.2

Released on 2018-04-16

  • configs for new parts
  • fix for exceptions
  • fix for solar panels
  • recompile for KSP 1.4.2


Version v2.3.10 for Kerbal Space Program 1.4.1

Released on 2018-03-14

  • don't overwrite stuff if the exponent is zero
  • recompile against KSP 1.4.1


Version v2.3.9 for Kerbal Space Program 1.3.1

Released on 2018-03-09

  • fix interaction with stock ModulePartVariants


Version v2.3.8 for Kerbal Space Program 1.3.1

Released on 2018-03-07

recompile for KSP 1.4
a few patches for new parts

Known issues:

the new stock texture switch messes up attachment nodes on scaled parts
(first switching and then scaling seems to work)


Version v2.3.7 for Kerbal Space Program 1.3.1

Released on 2017-10-13

  • recompile for KSP 1.3.1
  • only complain about negative dry mass if the number is significant


Version v2.3.6 for Kerbal Space Program 1.3.0

Released on 2017-05-28

  • recompile for KSP 1.3
  • lots of player-submitted patches (thanks eberkain, mikeloeven, OliverPA77)
  • set SRB thrust exponent to 3 (so both TWR and burntime are preserved now)
  • added a few null checks
  • scaling support for resource lists (for drills and converters)
  • Fix: don't scale mass if the part has a MFT module
  • TWEAKSCALEEXPONENTS should now affect not only the mentioned module but also derived modules (e.g. the exponent for ModuleRCS also applies for ModuleRCSFX)


Version v2.3.4 for Kerbal Space Program 1.2.2

Released on 2017-01-23

  • fix exponent for stock ModuleGenerator
  • found a way to write dryCost of the prefab early enough (fixes a cost issue with KIS)
  • functions to ask the prefab about stats of scaled parts (meant for KIS)


Version v2.3.3 for Kerbal Space Program 1.2.2

Released on 2016-12-17

  • recompile for KSP 1.2.2
  • fix cost bug with fsfuelswitch (ignore resource cost because FSfuelSwitch takes it into account)
  • added a bit of documentation


Version v2.3.2 for Kerbal Space Program 1.2

Released on 2016-11-03

  • update patches for RLA-Stockalike, OPT
  • exponents for ModuleRCSFX
  • remove an obsolete exponent
  • remove patches for relay antennas since scaling of their main function does not work (which is relaying signals when the antenna is part of an unloaded vessel)


Version v2.3.1 for Kerbal Space Program 1.2

Released on 2016-10-21

  • exponent for groundHeightOffset (fixes landing gears clipping the runway at launch)
  • fix for node positions reverting when cloning a part
  • antennas: refresh range display
  • antennas: tweak exponent (so that downscaled antennas are a bit less overpowered)


Version v2.3 for Kerbal Space Program 1.2

Released on 2016-10-15

  • fix for wheel colliders
  • fix wheelMotor torque and ec consumption
  • CrewCapacity: has a configurable exponent now
  • CrewCapacity: additional seats are not shown in the editor (stock limitation)
  • scaling support for FloatCurve (for wheel torque)
  • scaling support for and int values (for CrewCapacity)
  • fix scaling of input/outputResources (new stock "resHandler", e.g. consumption of reaction wheels)
  • move workaround for stock UI_ScaleEdit bug into the plugin


Version v2.2.13 for Kerbal Space Program 1.1.3

Released on 2016-06-24

  • recompile for KSP 1.1.3
  • fix for solar panels
  • rewrite of chainScaling: propagate relative scaling factor to child parts


Version v2.2.12 for Kerbal Space Program 1.1.2

Released on 2016-05-20

  • scaling of crew capacity (hardcoded to use the mass exponent for now)
  • Fix patches scale crewed parts with an exponent of 2 for crew and mass (not realistic but fits better to stock balance than 3). In any case mass/kerbal is hardcoded to be preserved.
  • scaling of the IVA overlay
  • support for new firespitter biplane
  • support for HLAirships module (thanks SpannerMonkey)
  • some missing patches for B9 (thanks BlowFish) (did some reordering but still need to sort through the content)
  • fixed a few patches
  • reorganize some patches into their own folder (B9, Squad including nasa and spacePlanePlus)
  • small optimisation: disable partModule in flight if not scaled


Version v2.2.11 for Kerbal Space Program 1.1.2

Released on 2016-05-12

  • remove obsolete IFS exponents
  • fix bug in partMessage for MFT
  • expose API via the part message system
  • fix for mirrored parts
  • workaround for tweakable bug: extra scaleFactor 500% for the free scaletypes (so the range from 200-400% is usable again)
  • don't interfere if other mods illegaly write part.mass. Print a warning in this case
  • fix thrust for moduleRCS (new maxFuelFlow exponent like for moduleEngines)


Version v2.2.10 for Kerbal Space Program 1.1.2

Released on 2016-05-05

  • basic wheel scaling: scaled wheels work but still behave strange. They roll, are pretty close to touching the ground, and are able to bounce.
  • make sure the exponents are applied before notifying other mods through the API (needed for interaction with FAR)
  • MFT support changed to TweakScale using their API (instead of the other way round)
  • tweaked downscaled science parts to be a little more expensive


Version v2.2.9 for Kerbal Space Program 1.1.2

Released on 2016-04-30

  • fix for drag cube scaling
  • update right click menu after rescale
  • recompile for 1.1.2
  • cleanup for mass scaling


Version v2.2.7.2 for Kerbal Space Program 1.1

Released on 2016-04-24

  • fix scaling of the root part


Version v2.2.7.1 for Kerbal Space Program 1.1

Released on 2016-04-23

  • update for 1.1
  • Workaround for the camera breaking (root part scaling is still broken)
  • support for new stock parts
  • shrinking science and probe cores makes them more expensive (only changed for stock so far)
  • update for the OPT v1.8 test release


Version v2.2.6 for Kerbal Space Program 1.0.5

Released on 2016-02-18

  • Support for NF-Construction
  • update for NFT Octo-Girders
  • fix for infinite loop between TweakScale and MFT
  • fix for engineer's report mass display
