At first glance, the configuration file for an addon is a pretty confusing and infuriating thing. This tutorial will walk through the individual parts of the configuration file and hopefully give you an idea what everything does. As we go along, we'll build up a dummy part file that will behave exactly like a real one, only lacking models, sounds, and textures.

Basic Part Making Guidelines

Before you delve into the part file, it's important that you make sure you check through your model for anything that might break the game on loading, but isn't related due to a CFG error. Before you start editing the part, make sure that:

  • The file is a .dae file. (For me, a .obj file simply doesn't work in game, and others have been saying the same thing. For conveniences sake, stick to .dae)
  • That every single mesh has a material, even the collision mesh.
  • That you've named the parts correctly. The collision mesh should always be called "node_collider", etc.

Part file creation

Okay, now that's out the way we can start looking into Part files, and how they work. Although it looks pretty confusing at first glance, it's actually a pretty simple ordeal to create one. To start, we're going to actually need an empty file in the right location.

  • Fire up notepad
  • Save it as "part.cfg" in the directory of your addon
    • Usually "../KerbalSpaceProgramDirectory/Parts/yourAddon"

There, you now have an empty file waiting for juicy bits of configuration to be stuck into it. So let's keep going.

Config file order

The part.cfg file has a pretty much specific order in which things are done. The order is:

// Title
// Name of your part
// 

// --- general parameters ---

// --- asset parameters ---

// --- node definitions ---

// --- FX definitions ---

// --- Sound FX definition ---

// --- editor parameters ---

// attachment rules: stack, srfAttach, allowStack, allowSrfAttach, allowCollision

// --- standard part parameters ---

// --- specific part parameters ---

So you'll notice those slashes in front of each title - that means that those lines have been commented out and so will not be read by Kerbal Space Program when it's loading your addon. From the point of view of the program, those lines don't exist. As we go through the tutorial, we'll build up the CFG file from it's bare bones to an actual working configuration file.

Give your part a title

If you look at the very, very top of most part files you'll notice a couple of lines that look like this:

// Kerbal Space Program - Configuration file
// My super awesome engine that can go at a kajillion miles per hour, lol

Those are quite simply, unimportant lines to KSP. The program doesn't read them, and doesn't give a crap about them either way. However, they are useful when other friendly people want to steal your work learn from your part file.

The first line simply states that this is a part file for KSP, and the second line is simply the name you give your part to other people to identify it.

So lets start creating our dummy CFG file.

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

Onwards!

General Parameters:

Now, let's look at the next section of the file - the general parameters.

// --- general parameters ---

This section comes straight under your title, and provides a few general things that apply to all parts. Here's a list of what goes under General Parameters:

name = solidBooster
module = SolidRocket
author = Il Carnefice

Pretty easy, huh? No? Still a bit muddled? Okay, explanation time.

name
This is just that, a name. It can be anything, but notice that it's NOT commented out. This is what KSP will refer to the part as internally. It's good form to keep it all one word. Don't worry, you won't see it called this in game, so it can honestly be anything. Must be unique and cannot contain the underscore.
module
Now this is slightly more difficult. Each part can be one of several different types of parts, defined by what comes after module. What type the part is defines how it works - for example, a solid rocket booster behaves differently from a liquid rocket motor. See Valid Part Modules for values you can use here.
author
Put your name here, you're the author!

So let's get on with our dummy file.

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

// --- General Parameters ---
name = LiquidThrusterV
module = LiquidEngine
author = YourName

There we go, a liquid engine type part, by proud author YourName.

Valid Part Modules

So what part types can you have?

Module Name Description
SolidRocket Use this module if you want to make something akin to a solid rocket booster - a continually burning rocket that does not have any thrust controls and cannot be turned off once lit.
LiquidEngine Use this if you want to make something more like an orbital maneuvering system - a rocket engine which has controllable thrust.
FuelTank Simply put, use this if you want to make your part contain fuel to feed to other parts.
CommandPod Feel like sticking three guys in your part and using it to control the rocket? Use this part.
SASModule This type of part stops the rocket from rotating and flipping and dropping off course.
Strut A connective module, which allows you to connect different rocket parts together.
Decoupler This connects rocket parts together but allows you to jettison itself and the parts it's connected to.
Radial Decoupler This connects parts together much like a Decoupler, but it behaves somewhat differently (as in ejection forces) since it assumes this part will connect laterally to the ship.
Parachutes This module can deploy a parachute to slow you down.
ControlSurface Movable wing-like surface. Can act as a rudder, aileron, elevator, canard or other aerodynamic control surface - function depends on placement on a ship.

Asset Parameters

This section defines the assets of our module - it provides us with links to our model and to our texture file, as well as giving us some extra settings to play around with.

// --- asset parameters ---
mesh = modelfile.dae
scale = 0.1
texture = texturemap.png
specPower = 0.5
rimFalloff = 3
alphaCutoff = 0

Lets go through them.

mesh
Easy, the name of the mesh you want to use for your model. Just write it's name in there, but keep the mesh file in the same directory as the part file.
scale
The scale of your model, depending on how you used the units in your 3D modelling program. If you used one unit = one meter, use a scale of 1. If it's 1 unit = 0.1 meters, use a scale of 0.1, that simple. I tend to stick to using a 0.1 scale factor and then scale my model to fit with the rest of the parts, it's easier than fiddling around with scale factors.
texture
The name of your texture file, which would be found inside the KSPDirectory/Parts/yourAddon/textures folder. Textures should be either 256x256, 512x512 or 1024x1024
specPower
The specular reflectivity of your part. It's best to leave it as it is.
rimFalloff
This defines the strength of the highlight effect in game. Higher values lead to a more pronounced effect near the edges.
alphaCutoff
This number defines the threshold for transparency on the part's texture. If your texture has an alpha channel (transparency), you can adjust this number to make sure your part is transparent or opaque where it should be. A value of 0 means nothing in the texture is considered to be transparent. A value of 1 means a completely transparent part.

There, that's everything under asset parameters covered. Let's continue building our dummy part file.

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

// --- General Parameters ---
name = LiquidThrusterV
module = LiquidEngine
author = YourName

// --- Asset Parameters ---
mesh = myMesh.dae
scale = 0.1
texture = awesometexture.png
specPower = 0.5 
rimFalloff = 3 
alphaCutoff = 0

Onwards!

Node Definitions

Another fairly easy section, this defines where we attach our part to other parts. You can have as many as you want, for example, tricouplers have four, three bottom and one top, while most parts simply have two, and a few parts have only one.

node_stack_bottom = x, y, z, angx, angy, angz, size
node_stack_top = x, y, z, angx, angy, angz, size
node_attach = x, y, z, angx, angy, angz, size

There's three example nodes. There are three different kinds, but only two are useful to us at the moment. We have node_stack and node_attach. Node stack is for defining where the part stacks vertically together with other parts, and node attach is used for defining where on the surface of your part other parts attach - so horizontal attachment.

A good idea is to make sure angx, angy, angz is set to 0, 1, 0 respectively to make the attachment point be directed upwards, but it's your choice.

Notice the identifier after node_stack - there's _top and _bottom. All these do is separate the nodes and make it easy for you to know which is which. You could call them node_stack_chicken and node_stack_bananabread if you wanted, as long as you know where those points correspond to.

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

// --- General Parameters ---
name = LiquidThrusterV
module = LiquidEngine
author = YourName

// --- Asset Parameters ---
mesh = myMesh.dae
scale = 0.1 
texture = awesometexture.png
specPower = 0.5 
rimFalloff = 3 
alphaCutoff = 0 

// --- Node Definitions ---
node_stack_bottom = 0.0, -3.5, 0.0, 0.0, 1.0, 0.0, 1.0

FX definitions:

More definitions! But this time, you're positioning the flame coming out the back of the rocket.

fx_exhaustFlame_yellow = x, y, z, angx, angy, angz, active
fx_exhaustLight_yellow = x, y, z, angx, angy, angz, active
fx_smokeTrail_medium = x, y, z, angx, angy, angz, active

Okay, looks pretty similar to node_definitions, right?

You'll notice, just like node definitions, there are separate parts to each effect. You have fx_exhaustFlame, fx_exhaustLight, and fx_smokeTrail.

There are exactly what they sound like, the flame, the light, and the smoke trail.

There are variations on flame color, blue is also an option. To get a blue flame, you would use fx_exhaustFlame_blue. You would do the same for the exhaustLight.

The 'active' switch on the end is used to define when this effect will be visible. See the FX Groups listing to know which effect groups are available, and when they are used. It's also possible to assign an effect to more than just one FX Group. If for instance, you want a smoke effect to be visible both whe the part activates and also when it deactivates itself, you can do this:

fx_gasBurst_white = x, y ,z, angx, angy, angz, activate, deactivate

This is particularly useful if you're defining a lot of effects, like the gas discharges on an RCS module.

Feel like you're getting the hang of this now? Let's keep building the dummy part file, and add in a blue flame and light, but leave out the smoke trail.

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

// --- General Parameters ---
name = LiquidThrusterV
module = LiquidEngine
author = YourName

// --- Asset Parameters ---
mesh = myMesh.dae
scale = 0.1
texture = awesometexture.png
specPower = 0.5 
rimFalloff = 3 
alphaCutoff = 0

// --- Node Definitions ---
node_stack_bottom = 0.0, -3.5, 0.0, 0.0, 1.0, 0.0, 1.0

// --- FX Definitions ---
fx_exhaustFlame_blue = 0.0, -10.0, 0.0, 0.0, 1.0, 0.0, active
fx_exhaustLight_blue = 0.0, -10.0, 0.0, 0.0, 0.0, 1.0, active

Sound FX definition

This is pretty easy to use in a basic way, which will suit our needs just fine.

Under this section, comes:

sound_vent_medium = activate
sound_rocket_hard = active
sound_vent_soft = deactivate

Sounds are added to FX Groups, in much the same way smoke and flame effects are. Of course, sounds do not need to be positioned in space, nor do they have rotations, so all you need is to indicate in which FX Group the sound will be executed. As with effects, you can assign multiple groups to a sound.

There are 3 ways to add a sound to a part. KSP has an internal sound library, which contains a few sound effects. By defining a sound as in the example above, KSP will search for that sound in it's internal library. KSP also has a Sounds folder on it's main directory. This folder contains sounds that are available to every part in the Parts folder. To use a sound from the Sounds folder, you must include the file extension in the sound name (e.g., sound_vent_medium.wav = activate) The 3rd way is to include your own sound effects to your Part folder (e.g., KSPDirectory/Parts/MyPartFolder/Sounds), and define your sound effect in the same manner as above.

REMEMBER: If you add a custom sound, the file name must start with sound_ (e.g., sound_myNewSoundEffect.wav).

Sounds added to a Sounds folder inside the Part folder may not be accessed by other parts. Think of those as 'private' sounds.

Adding sound FX to our dummy part file:

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

// --- General Parameters ---
name = LiquidThrusterV
module = LiquidEngine
author = YourName

// --- Asset Parameters ---
mesh = myMesh.dae
scale = 0.1 
texture = awesometexture.png
specPower = 0.5 
rimFalloff = 3 
alphaCutoff = 0 

// --- Node Definitions ---
node_stack_bottom = 0.0, -3.5, 0.0, 0.0, 1.0, 0.0, 1.0

*'''// --- FX Definitions ---
fx_exhaustFlame_blue = 0.0, -10.0, 0.0, 0.0, 1.0, 0.0, active
fx_exhaustLight_blue = 0.0, -10.0, 0.0, 0.0, 0.0, 1.0, active

// --- Sound FX definition ---
sound_vent_medium = activate
sound_rocket_hard = active
sound_vent_soft = deactivate

Editor Parameters:

Aha! We're back to parameters! These set of parameters let us decide how our part is displayed in the rocket editor. This section has the following:

// --- editor parameters ---
cost = 450
category = 0
subcategory = 0
title = 
manufacturer =
description = 
cost
This hasn't really been implemented yet, but when it is it sets the cost for spaceship parts. You can set this to anything for now, it's entirely up to you.
category
There are six categories:
Name ID Description
Propulsion 0 Put your engine here!
Command and Control 1 Command pods and SAS modules here
Structural and Aerodynamic 2 Struts, wings, and supporting things
Utility and Scientific 3 Parachutes, Escape towers, heat shields
Decals No use yet.
Crew No use yet.
subcategory
No use yet. Set it to 0
title
What do you want your part to be called in the rocket editor?
manufacturer
Who built your part?
description
Describe your part here. (Do not use linebreaks. KSP breaks lines automatically in the part's tooltip. A linebreak will cause your description to appear truncated)

And that's that. Updating the dummy cfg file now:

// Kerbal Space Program - Part CFG file
// Mark V Rocket Engine

// --- General Parameters ---
name = LiquidThrusterV
module = LiquidEngine
author = YourName

// --- Asset Parameters ---
mesh = myMesh.dae
scale = 0.1

alphaCutoff = 0 

// --- Node Definitions ---

*'''// --- FX Definitions ---
fx_exhaustFlame_blue = 0.0, -10.0, 0.0, 0.0, 1.0, 0.0, active

// --- Sound FX definition ---
sound_vent_medium = activate
sound_rocket_hard = active
sound_vent_soft = deactivate

// --- editor parameters ---
cost = 120
category = 0
subcategory = 0
title = Mark V Rocket Engine
manufacturer = Awesomely Terrible Spaceship Engines Inc.
description = This part will now get you to space with 60% less limb loss than the mark IV engine.

Attachment rules:

This defines how your part attaches to other parts.

  • // attachment rules: stack, srfAttach, allowStack, allowSrfAttach, allowCollision
  • attachRules = 1,1,1,1,1

The rules correspond to the numbers below - one is allow, 0 is prevent. The tags are:

stack - Can your part be stacked on others?

SrfAttach - Can your part be placed onto a surface?

allowStack - Will you allow other parts to be stacked on your part?

allowSrfAttach Can other parts be placed on the surface of yours?

allowCollision - A special one: Can your part be placed if part of it is intersecting another part?


Note that you can also force parts attached to this part to attach in a specific symmetry.

  • // symmetry rules: 0=1x, 1=2x, 2=3x, 3=4x and so on...
  • stackSymmetry = 3


Easy enough, right? Adding to dummy file and continuing.

Standard Part Parameters:

This defines how your part performs in the air and it's limits. Note that not all of these parameters need to be defined. If they're left out of the cfg file, KSP will use a default value for them.

  • mass =
  • dragModelType = default
  • maximum_drag =
  • minimum_drag =
  • angularDrag =
  • crashTolerance =
  • breakingForce =
  • breakingTorque =
  • maxTemp =
  • heatConductivity =
  • heatDissipation =
  • stageBefore =
  • stageAfter =

mass - How much does your part weigh? (Or, for parts that also specify a dryMass parameter, how much does it weigh when full?)

dragModelType - Leave this as default.

maximum_drag - What's the maximum amount of drag on your part? (Usually under 1.)

minimum_drag - The minimum amount of drag your part will encounter. (Usually under 1 and lower than maximum_drag) (this value is unused if dragModelType is set to default)

angularDrag - how much angular drag is there? (Also usually under 1.)

crashTolerance - How good is your part at surviving crashes? The higher the number the more durable. Numbers are approximately maximum impact speed in m/s.

breakingForce - How much will the attachment between this part and the part it's connected to resist to linear forces?

breakingTorque - How much will the attachment resist rotational forces?

maxTemp - The maximum temperature your part can experience before exploding.

heatConductivity - How good is your part at conducting heat? Defaults to 0.08, CFG values are used in 0.13.3, but not in 0.15.2.

heatDissipation - How good is your part at dissipating heat from the ship? Defaults to 0.08, CFG values are used in 0.13.3, but not in 0.15.2.

stageBefore and stageAfter - Can be True or False. defines whether this part will create a new stage before or after itself, or both (as do decouplers). This only applies for the automatically generated staging sequence.

There you go, another section down.

  • // Kerbal Space Program - Part CFG file

  • maximum_drag = 0.4
  • minimum_drag = 0.2
  • angularDrag = 0.2
  • crashTolerance = 5
  • maxTemp = 2500

Specific Part Parameters:

We're almost finished, a complete part is almost at our hands and you should know almost everything you need to create a part.cfg file. However, remember back when we were setting types? Well each type has an individual set of specific part parameters that change depending on what type of part it is.

You cannot mix and match parameters from different module types - it doesn't work.

These specific parameters are actually public variables defined in the Part classes themselves. The standard parameters are declared in the Part base class, and the specific ones in each Part extension (i.e., Modules)

For example, if your part type (module) was SolidRocket, your specific part parameters would be composed of:

  • thrust = 130
  • dryMass = 0.36
  • heatProduction = 550
  • fuelConsumption = 4
  • internalFuel = 100
  • fullExplosionPotential = 0.8
  • emptyExplosionPotential = 0.1
  • thrustCenter = 0, -0.5, 0
  • thrustVector = 0, 1, 0

Time to go through and see what special parameters each module can have.

Liquid Engine

A liquid engine has the following special parameters:

  • maxThrust =
  • minThrust =
  • heatProduction =
  • fuelConsumption =

Looks pretty easy, and everything is pretty much what you'd expect. By now, you should be able to work out what they all mean, but just in case:

maxThrust - The maximum thrust of the liquid engine.

minThrust - The minimum thrust. Usually 0, unless you want a rocket that can't fully be turned off.

heatProduction - How much heat your rocket puts out.

fuelConsumption - How much fuel your rocket uses.

Solid Rocket Booster

  • thrust =
  • dryMass =
  • heatProduction =
  • fuelConsumption =
  • internalFuel =
  • fullExplosionPotential =
  • emptyExplosionPotential =
  • thrustCenter = x, y, z
  • thrustVector = angx, angy, angz

A lot of those values look pretty similar to the liquid engine parameters, right?

thrust - The thrust of the solid rocket booster. Note how there is no minimum thrust because it can not be turned off once lit.

dryMass - How much the SRB weighs when empty.

heatProduction - Exactly the same as the liquid rocket, how much heat your rocket puts up.

fuelConsumption - How much fuel the rocket uses per second.

internalFuel - How much fuel does the SRB hold inside it?

fullExplosionPotential - The potential for explosion when the rocket is full of fuel

emptyExplosionPotential - And the potential when it's empty.

thrustCenter - Where the thrust comes from.

thrustVector - And which direction it goes.

Fuel Tank

Fuel tanks are a bit different, seeing as they have no thrust parameters.

  • fuel =
  • dryMass =
  • fullExplosionPotential =
  • emptyExplosionPotential =

If you've read above, you should know exactly what those parameters do, and so I won't explain them to you again.

SAS Module

  • maxTorque =

maxTorque - The maximum amount of torque the module can apply to halt the ship's rotation.

Ki, Kd and Kp - These parameters allow for tuning of the internal workings of the SAS module. If you're not experienced in working with PID controllers, just leave them as they are.

Winglets

  • dragCoeff =
  • deflectionLiftCoeff =

dragCoeff - The drag co-efficiency of the wings.

deflectionLiftCoeff - How much lift the wings generate.

Control Surfaces

  • dragCoeff =
  • deflectionLiftCoeff =
  • ctrlSurfaceRange =
  • ctrlSurfaceArea =

ctrlSurfaceRange - How far off centre the control surface (rudder / aileron etc) can move under control

ctrlSurfaceArea - The effective surface area of the control surface - the bigger the surface, the bigger the surface area must be set to

Decouplers

  • ejectionForce =

ejectionForce - How hard it separates on stage ejection.

Note, decouplers also add two lines to Standard Part Parameters, "stageAfter = True" and "stageBefore = True"

Parachutes

  • useAGL =
  • autoDeployDelay =
  • minAirPressureToOpen =
  • deployAltitude =
  • closedDrag =
  • semiDeployedDrag =
  • fullyDeployedDrag =

useAGL - Whether or not the parachute opens at the set altitude above ground level, instead of above sea level.

autoDeployDelay - Time before parachutes attached to jettisoned parts are activated.

minAirPressureToOpen - The minimum air pressure required before the chute will activate.

deployAltitude - At what altitude the parachute deploys fully once activated.

closedDrag - The drag when the parachute is closed.

semiDeployedDrag - The drag when it's semi-deployed

fullyDeployedDrag - And finally, the drag when it's entirely deployed.

Conclusion:

There you go then. By now, you should know the ins and outs of the part.cfg file, and how to create one, edit one, play around with one, etc. All sorts of cool stuff like that. The final dummy part.cfg file will be after this, with the special part parameters added in.

Anyway, that's that, now you know, now go make some cool addons like FTL drives and newton-defying inertial dampeners.
