Outdated Mod

This mod is not known to work with the latest version of Kerbal Space Program. Proceed with caution.



TextureReplacer is a plugin for Kerbal Space Program that allows you to replace stock textures and customise your Kerbals. More specifically, it can:

  • replace stock textures with custom ones,
  • assign personalised skin and suit textures for each Kerbal,
  • assign suits based on class and experience level,
  • toggle between EVA suit and IVA suit without helmet in breathable atmosphere,
  • add reflections to parts and helmet visors and
  • change bilinear texture filter to trilinear to improve mipmap quality.

Special thanks to:

  • RangeMachine for contributing reflection shaders and maintaining the mod in my absence.
  • rbray89 who contributed a reflective visor shader and for Active Texture Management and Visual Enhancements where some code has been borrowed from,
  • Tingle for Universe Replacer; studying his code helped me a lot while developing this plugin,
  • taniwha for KerbalStats that was optionally used by this plugin for gender determination and role-based suit assignment,
  • Razchek and Starwaster for Reflection Plugin where I learnt how to implement reflections,
  • sarbian for fixing an issue with non-multiple-of-4 texture dimensions,
  • therealcrow999 for testing and benchmarking this plugin,
  • Ippo343 for contributing KSP-AVC configuration,
  • JPLRepo for contributing DeepFreeze compatibility fixes,
  • Proot, Scart91, Green Skull and others for creating texture packs and
  • Sylith and Scart91 for giving others permissions to make derivatives of their texture packs.


General Textures

General replacement textures are of the form


where <internalName> is the texture's internal name in KSP or path of a texture inside GameData/ (plus .dds/.png/.jpg/.tga extension, of course).

It's also possible to replace textures from GameData/ if one specifies the full directory hierarchy:

  Squad/Parts/Command/Mk1-2Pod/model000  // Mk1-2 pod texture
  Squad/Parts/Command/Mk1-2Pod/model001  // Mk1-2 pod normal map

Note that all texture and directory names are case-sensitive!


Reflections are shown on visors of Kerbals' helmets and on parts that include TRReflection module that can be used like in the following example adding reflections onto the windows of Mk1-2 pod:

  name = TRReflection
  shader = Reflective/Bumped Diffuse
  colour = 1.0 1.0 1.0
  interval = 1
  meshes = FrontWindow SideWindow

There are several parameters, all optional:

  • shader: Most shaders should be automatically mapped to their reflective counterparts. In some cases, however, there are no reflective version of a shader, so you will have to manually specify appropriate shader.
  • colour: Reflection is pre-multiplied by this RGB value before added to the material. 1.0 1.0 1.0 by default.
  • interval: Once in how many steps the reflection is updated. 1 by default.
  • meshes: Space- and/or comma-separated list of mesh names where to apply reflections. Reflection is applied to whole part if this parameter is empty or non-existent. You may find logReflectiveMeshes configuration option very helpful as it prints names of all meshes for each part with TRReflection module into your log.

One face of one reflection cube texture is updated every reflectionInterval frames (2 by default, it can be changed in a configuration file), so each reflective part has to be updated six times to update all six texture faces. More reflective parts there are on the scene less frequently they are updated. interval field on TRReflection module can lessen the update rate for a part; e.g. interval = 2 makes the part update half less frequently.

Personalised Kerbal Textures

Skins and suits are assigned either manually or automatically (configured in the GUI while configuration files can provide initial settings). "Random" assignment of skins and suits is based on Kerbals' names, which ensures the same skin/suit is always assigned to a given Kerbal. Additionally, special per-class suit can be set for each class.

Skin textures reside inside Skins/ directory, each in its own subdirectory:

  kerbalHead    // Head texture
  eyeballLeft   // Left eyeball
  eyeballRight  // Right eyeball
  pupilLeft     // Left pupil
  pupilRight    // Right pupil

Directory name should have an extension containing letters that convey additional information about that skin:

  • 'm' male,
  • 'f' female,
  • 'e' hide eyes (for skins that have eyes drawn on texture),
  • 'x' excluded from automatic assignment, can only be assigned manually.

E.g. skin GameData/TextureReplacer/Skins/MySkin.fx will be assigned to females only and only if explicitly selected (by CustomKerbals in a config file or later in the in-game GUI).

Suit textures' names are identical as for the default texture replacement except that class level variants of suit texture are possible. Each suit must reside inside its own directory.

  kerbalMain                   // IVA suit (veteran)
  kerbalMainGrey               // IVA suit (level 0)
  kerbalMainGrey1              // IVA suit (level 1)
  kerbalMainGrey2              // IVA suit (level 2)
  kerbalMainGrey3              // IVA suit (level 3)
  kerbalMainGrey4              // IVA suit (level 4)
  kerbalMainGrey5              // IVA suit (level 5)
  kerbalMainNRM                // IVA suit normal map
  kerbalVisor                  // IVA helmet visor

  EVAtexture                   // EVA suit (level 0)
  EVAtexture1                  // EVA suit (level 1)
  EVAtexture2                  // EVA suit (level 2)
  EVAtexture3                  // EVA suit (level 3)
  EVAtexture4                  // EVA suit (level 4)
  EVAtexture5                  // EVA suit (level 5)
  EVAtextureNRM                // EVA suit normal map
  futureSuit_emissive          // EVA suit emissive (future suit only)
  EVAvisor                     // EVA helmet visor
  EVAjetpack                   // EVA jetpack
  EVAjetpackNRM                // EVA jetpack normal map
  EVAjetpackEmmisive           // EVA jetpack emissive

  cargoContainerPack_diffuse   // EVA cargo backpack
  cargoContainerPack_NRM       // EVA cargo backpack normal map
  cargoContainerPack_emissive  // EVA cargo backpack emissive

  backpack_Diff                // EVA parachute backpack
  backpack_NM                  // EVA parachute backpack normal map
  canopy_Diff                  // EVA parachute canopy
  canopy_NR                    // EVA parachute canopy normal map

The veteran and level textures are optional. If a level texture is missing the one from the previous level is inherited. If the veteran texture is present it is used for all levels on veterans.

Directories may optionally have a suffix containing any combination of the following letters (in an arbitrary order):

  • 'm' to make the suit male-only,
  • 'f' to make the suit female-only,
  • 'x' exclude form automatic assignment,
  • 'S' if containing textures for the slim suit model,
  • 'V' if containing textures for the vintage suit model (Making History),
  • 'F' if containing textures for the future suit model (Breaking Ground).

Configuration File

NOTE: All options that can be configured in the GUI are saved per-game and not in the configuration files. Configuration files only provide initial settings for those options.

Main/default configuration file:


One can also use additional configuration files; configuration is merged from all *.cfg files containing TextureReplacer { ... } as the root node. This should prove useful to developers of texture packs so they can distribute pack-specific skin/suit assignment rules in a separate file. All *.cfg files (including @Default.cfg) are processed in alphabetical order (the leading @ in @Default.cfg ensures it is processed first and overridden by subsequent custom configuration files).

Normal Maps

Unity uses grey normal maps (RGBA = YYYX) to minimise artefacts when applying DXT5 texture compression on them. When a normal map has a NRM suffix Unity converts it from RGB = XYZ (blue) to RGBA = YYYX (grey) normal map unless it is in DDS format.

In short: you should supply blue normal maps when a texture has NRM suffix and is in PNG format (JPEGs and TGAs are not recommended for normal maps) and grey normal maps for textures in DDS format or without NRM suffix.

Grey normal maps can be created by saving the standard blue normal maps as DDS with DXT5nm compression or by manually shuffling channels: RGBA -> GGGR.


  • Use DDS format for optimal RAM usage and loading times since DDS textures are not shadowed in RAM and can be pre-compressed and can have pre-built mipmaps.
  • Try to keep dimensions of all textures powers of two.
  • The planet textures being replaced are the high-altitude textures, which are also used in the map mode and in the tracking station. When getting closer to the surface those textures are slowly interpolated into the high-resolution ones that cannot be replaced by this plugin.

Known Issues

  • Switches between suit types (standard, vintage and future) done via stock GUI will only be reflected in TextureReplacer's GUI after the next scene load.
  • (KSP bug) Head meshes have mismatched tangents and/or binormals along the back of the head, where the texture is stitched together.
  • Clouds from EVE are not reflected at certain altitudes.
