This is the main page of the '''Custom Track Tutorial'''. Here, you'll see a brief overview of the [[SZS]] (track) file, a listing of programs you might need to edit them and in-depth tutorials on creating and editing each of the files. All files and sections are combined together to form a track, so it is important to know what each of them does while working with them. It is important to read all the tutorials and topics thoroughly '''before starting to make the track'''. The tutorials are presented in an order, however, you will find yourself jumping to previous and later steps, as it's impossible to define a strict "order" of building the track. During this process, it's common, even for advanced track makers, to run into issues or freezes of unknown origin. This is also addressed in the tutorial.

Mario Kart Wii uses SZS files to store track data; all of the original tracks can be found and extracted from the game's ISO using a program such as [[WiiScrubber]] or [[Wiimms ISO Tools]]. You will mainly be working with the following files when creating a custom track; they are all required for your track to load and work.

:*'''map_model.brres'''
+
An '''SZS''' archive typically contains many other files: [[Object]]s are usually composed of one or more files, and all associated files must be present for the track to load and the object to function properly. They might include '''BRRES''' files, which contain models, textures, "bones" and multiple types of animation and '''KCL''' files for objects with collision (although some solid objects do not use KCLs for collision). You may also find folders labeled '''effect''' and '''brasd'''. '''Effects''' include water splashes (Pocha), snow and fireworks (Hanabi). The '''brasd''' folder contains animations, needed for Goombas (Kuribo), Chain Chomps (Wanwan), flags, cannons, and other items. Files can also be imported, exported or deleted from an SZS file as needed.

An '''SZS''' archive typically contains many other files.  These include '''BRRES''' files, which are the models of [[objects]] used in the level.  BRRES files can also contain textures, "bones" and multiple types of animation.  You may also find folders labeled '''posteffects''', '''effects''' and '''brasd'''.  '''Post effects''' include fog ([[BFG]] files) and bloom settings ([[BBLM]] files).  '''Effects''' include water splashes (Pocha), snow and fireworks (Hanabi.)  The '''brasd''' folder contains animations, needed for Goombas (Kuribo), Chain Chomps (Wanwan), flags, cannons and other items. Please note that if you plan to use an object with effects or animations, you will need  all its associated files in your SZS, otherwise your level will freeze on load.  Files can also be imported, exported or deleted from an SZS file as needed using [[SZS Explorer]].
+
*'''Track Files'''
 +
::You will need to obtain the SZS files of Mario Kart Wii's original tracks to use the object files (such as the item box) and maybe the KMP and vrcorn_model from them. You can see how to extract them from your Wii game disc in the [[Obtain Original Track Files]] page.
  
−
==Required Programs and Files==
+
*'''[[Wiimms SZS Tools]]'''
 +
::These command-line tools can perform many tasks efficiently. They allow the creation of compressed SZS files automatically using scripts (batch files) and checking/fixing errors in KMP, KCL and SZS files. It can adjust the minimap automatically and can generate KCL files directly from OBJ imports.
 +
::*'''[[Wiimm's Tool Manager]]''' is a simple GUI for Wiimms SZS Tools.
 +
::*You can download a pack of batch files with simple scripts which can be used on this tutorial [http://www.mediafire.com/file/bb30qwtrrh0ilfw/CTTutorial_WiimmsSZSTools_ScriptPack.zip here].
  
−
You will need to download these programs and a track file to use as a base for your new level.
+
*'''[[CTools Pack]]'''
 +
::The multiple programs contained in this pack are used to load and edit [[SZS]], [[BMG]], [[TPL]], [[BRRES]] and [[KCL]] files. Only the following two will be used in these tutorials:
 +
:::*'''[[CTools Pack#SZS Explorer|SZS Explorer]]'''
 +
::::It can open SZS archives and manage the files inside, by adding or removing them. Double-clicking on an object inside an SZS archive will open it in an external editor, if available.
 +
:::*'''[[CTools Pack#BRRES Editor|BRRES Editor]]'''
 +
::::This program is used to view models and convert OBJ-format models (exported with 3D modeling programs) to the BRRES model format used in Mario Kart Wii. It is also used to import and export textures without otherwise altering a model.
 +
::If you use Wiimms SZS Tools to manage your SZS file and [[Custom Track Tutorial#BrawlBox|BrawlBox]] to import your models, this pack is not needed (recommended for advanced users).
  
−
* '''[[CTools Pack]]'''  
+
*'''[[3D Tool]]'''
−
::This is a collection of Custom Track tools including:
+
::Most 3D model editors can be used to create a Mario Kart Wii track. '''[[Google SketchUp]]''' is the recommended tool for beginners. [[3ds Max]] can be used for more advanced editing.
  
−
::*'''[[CTools Pack#SZS Explorer|SZS Explorer]]'''  
+
*A '''KMP Editor''':
−
:::This program is used to load an SZS file archive and manage the files inside, such as the course and map models. Double clicking on an object inside an SZS archive will open it in an external editor, if available.  
+
::*'''[[KMP Cloud]]'''
 +
::::This program can edit and expand KMP data. It allows you to add or remove extra objects, checkpoints, respawn points, etc.
 +
::*'''[[KMP Modifier]]'''
 +
::::A tool giving an overview of the whole KMP file and is able to add/delete/move points with a click of the mouse button. For more complex models an imported map model OBJ file can be used to directly calculate the height values.
 +
::*'''[[Wiimms SZS Tools|wkmpt or wszst (Wiimms SZS Tool)]]'''
 +
:::: Both tools convert a KMP file into a text file, which can be edited with any text editor. And both tools use an [http://szs.wiimm.de/info/kmp-guide.html internal compiler] to re-create the KMP.
  
−
::*'''[[CTools Pack#BRRES Editor|BRRES Editor]]'''
+
=== Advanced ===
−
:::This program is used to view models and convert OBJ-format models (exported with 3D modeling programs) to the [[BRRES]] model format used in Mario Kart Wii.  It is also used to import and export textures without otherwise altering a model.
+
These are optional programs and tools that can enhance your track.   
  
−
* '''[[SZS Modifier]]'''
+
*'''Image Editor'''
−
::This program is the predecessor of CTools. It's required for editing things that CTools currently cannot edit. It is also better for certain tasks that CTools can handle, such as creating minimaps and editing KCL data, as both of these features in CTools have problems that will produce glitches in-game. Unlike CTools, SZS Modifier ''cannot'' expand files to make them larger than the originals.
+
::Adobe Photoshop, GIMP, and Paint.NET are just a few examples. Since they are free, GIMP and Paint.net are recommended; Paint.net is much faster and lighter while GIMP is slower but more powerful.
  
−
* '''Model Editor'''
+
*'''[[BrawlBox]]'''
−
::* '''[[Modeling With 3D Editor|Google SketchUp]]''' ''(Recommended)''
+
::This program is originally designed for Super Smash Bros. Brawl, but can edit Mario Kart Wii's files as well. You can convert DAE files, which have more features than OBJ files, to the BRRES model format. This way other features that the BRRES model format supports, like vertex painting and more complex materials, can be converted too. It also allows the creation of BRSTM files for custom music.
−
::* 3DS Max (Recommended for advanced modellers or for proper texture mapping of Sketchup models)
 
−
::* Any other 3D modeler program; usually needs to be used along with '''[[Modeling With 3D Editor|Blender]]''' or '''[[Modeling With 3D Editor|3DS Max]]'''.
 
  
−
* '''Track Files'''
+
*'''[[Material Tool]]
−
::You can base your level on one of Mario Kart Wii's track files, such as ''beginner_course'' (Wii Luigi Circuit), ''castle_course'' (Wii Mario Circuit) or ''old_mario_64'' (N64 Mario Raceway.)  These levels all have fairly easy to understand KMPs.  This option is usually preferable, as long as you have [[Obtain Original Track Files| access to the original files]].
+
::This tool edits the properties of the materials in MDL0 files.
  
−
::You can also base your track off of another custom track.  [[Rooster Island]] works well as it can replace almost any track and is based on castle_course's KMP.  [[Fishdom Island]] is another good choice if you need more complex checkpoints, item routes and enemy routes.  Or you can create an SZS file from scratch using CTools.  If you create the SZS with CTools you will need to import KMP and the KCL files from another Nintendo or custom track into your SZS. Some dedicated CT creators have managed to create their own glitch-free KCL or KMP files, such as the KCL at [[Sunset Ridge]].
+
*'''[[KMP3D]]'''
 +
::KMP3D is a plugin for Google SketchUp 6 and later that can help custom track authors with the KMP.
  
−
====Optional/Advanced====
+

 +
::MagicY is a tool which works together with KMP Cloud to [[Automated height correction|automatically calculate Y coordinates]] for KMP entries.
  
−
These are helpful programs that can enhance your track.
+
*'''[[Hexadecimal|Hex Editor]]'''
 +
::A Hex Editor is included with CTools, but this technique is for experienced hackers or experimental purposes only. Some files, such as post-effects and animation files, cannot be edited with the current suite of programs. Hex Editing is the only option in cases like these and can lead to greater understanding of these files.

Introduction

This is the main page of the Custom Track Tutorial. Here, you'll see a brief overview of the SZS (track) file, a listing of programs you might need to edit them and in-depth tutorials on creating and editing each of the files. All files and sections are combined together to form a track, so it is important to know what each of them does while working with them. It is important to read all the tutorials and topics thoroughly before starting to make the track. The tutorials are presented in an order, however, you will find yourself jumping to previous and later steps, as it's impossible to define a strict "order" of building the track. During this process, it's common, even for advanced track makers, to run into issues or freezes of unknown origin. This is also addressed in the tutorial.

You can use the blue links box at the bottom of each page to navigate faster through the tutorials. If you have any questions, you may post them on the talk page (please sign your posts with --~~~~).

Overview of a Custom Track File

A view of SZS Explorer showing SZS file structure.

Mario Kart Wii uses SZS files to store track data; all of the original tracks can be found and extracted from the game's ISO using a program such as WiiScrubber or Wiimms ISO Tools. You will mainly be working with the following files when creating a custom track; they are all required for your track to load and work.

SZS is an archive format used by Nintendo for many types of data, and is similar to a ZIP or RAR file. Your SZS file will contain all the files needed by your track, including:
  • course_model.brres and vrcorn_model.brres
BRRES files contain 3D models and textures. They have no solidity of their own. The course_model.brres defines the main course model of the track and vrcorn_model.brres defines the model of the background, usually the sky.
  • map_model.brres
This is the minimap model, which is a textureless 3D model that is displayed in-game from a birds-eye viewpoint.
This is the 3D model that defines collision data. It determines what parts of the level can be driven on, where the walls and boost pads are, and which parts of the level are out of bounds.
This is a binary data file which controls the placement of all objects in a level, including item boxes and other animated objects such as trees, as well as enemy routes, start positions, checkpoints, and intro and replay cameras.
  • posteffect folder
This folder contains data for effects such as fog, glow, bloom and lightning, simulating the natural environment of the world.

An SZS archive typically contains many other files: Objects are usually composed of one or more files, and all associated files must be present for the track to load and the object to function properly. They might include BRRES files, which contain models, textures, "bones" and multiple types of animation and KCL files for objects with collision (although some solid objects do not use KCLs for collision). You may also find folders labeled effect and brasd. Effects include water splashes (Pocha), snow and fireworks (Hanabi). The brasd folder contains animations, needed for Goombas (Kuribo), Chain Chomps (Wanwan), flags, cannons, and other items. Files can also be imported, exported or deleted from an SZS file as needed.

Programs and Files

The following programs and files are recommended for you to create your track. Some of them are required, and some are optional.

  • Track Files
You will need to obtain the SZS files of Mario Kart Wii's original tracks to use the object files (such as the item box) and maybe the KMP and vrcorn_model from them. You can see how to extract them from your Wii game disc in the Obtain Original Track Files page.
These command-line tools can perform many tasks efficiently. They allow the creation of compressed SZS files automatically using scripts (batch files) and checking/fixing errors in KMP, KCL and SZS files. It can adjust the minimap automatically and can generate KCL files directly from OBJ imports.
  • Wiimm's Tool Manager is a simple GUI for Wiimms SZS Tools.
  • You can download a pack of batch files with simple scripts which can be used on this tutorial here.
The multiple programs contained in this pack are used to load and edit SZS, BMG, TPL, BRRES and KCL files. Only the following two will be used in these tutorials:
It can open SZS archives and manage the files inside, by adding or removing them. Double-clicking on an object inside an SZS archive will open it in an external editor, if available.
This program is used to view models and convert OBJ-format models (exported with 3D modeling programs) to the BRRES model format used in Mario Kart Wii. It is also used to import and export textures without otherwise altering a model.
If you use Wiimms SZS Tools to manage your SZS file and BrawlBox to import your models, this pack is not needed (recommended for advanced users).
Most 3D model editors can be used to create a Mario Kart Wii track. Google SketchUp is the recommended tool for beginners. 3ds Max can be used for more advanced editing.
  • A KMP Editor:
This program can edit and expand KMP data. It allows you to add or remove extra objects, checkpoints, respawn points, etc.
A tool giving an overview of the whole KMP file and is able to add/delete/move points with a click of the mouse button. For more complex models an imported map model OBJ file can be used to directly calculate the height values.
Both tools convert a KMP file into a text file, which can be edited with any text editor. And both tools use an internal compiler to re-create the KMP.

Advanced

These are optional programs and tools that can enhance your track.

  • Image Editor
Adobe Photoshop, GIMP, and Paint.NET are just a few examples. Since they are free, GIMP and Paint.net are recommended; Paint.net is much faster and lighter while GIMP is slower but more powerful.
This program is originally designed for Super Smash Bros. Brawl, but can edit Mario Kart Wii's files as well. You can convert DAE files, which have more features than OBJ files, to the BRRES model format. This way other features that the BRRES model format supports, like vertex painting and more complex materials, can be converted too. It also allows the creation of BRSTM files for custom music.
This tool edits the properties of the materials in MDL0 files.
KMP3D is a plugin for Google SketchUp 6 and later that can help custom track authors with the KMP.
MagicY is a tool which works together with KMP Cloud to automatically calculate Y coordinates for KMP entries.
A Hex Editor is included with CTools, but this technique is for experienced hackers or experimental purposes only. Some files, such as post-effects and animation files, cannot be edited with the current suite of programs. Hex Editing is the only option in cases like these and can lead to greater understanding of these files.

Tutorial Archive

The following programs and tutorials are outdated and/or obsolete and not recommended.

Software

This program is the predecessor of CTools. It can be used for editing things that CTools currently cannot. It is also better for certain tasks that CTools can handle, such as creating minimaps and editing KCL data, as both of these features in CTools have problems that will produce glitches in-game. Unlike CTools, SZS Modifier cannot expand files to make them larger than the originals.
