Custom Effects

This page is a part of the Custom Track Tutorial. Back to the main tutorial page.

Introduction

It is possible to change the Lightning color and various other on-screen effects (such as Blooper ink or wheelie particles) through editing BREFF and BREFT files. If creating a texture pack, every effect is able to be changed. These can all be found within files → Race → Common.szs. Extract this file using Wiimms SZS Tools to access the BREFF and BREFT files. Edit the BREFT file using BrawlBox/BrawlCrate. While BrawlCrate can view BREFF files, it tends to not save any edits made, or corrupt the BREFF file. Therefore, edit the BREFF file using either the BREFF Editor or directly edit the hex values, and follow documentation on the file. Then, to recompile back into the Common.szs file, using Wiimms SZS Tools, run the CREATE command on the .d folder.

If creating a custom track, the game will be able to read custom BREFF/BREFT files found within RKRace.breff/breft (within the Common.szs). Note, however, that other Common.szs subfiles will not be able to be read by the game, and instead will default to the game's BREFF files (instead of those found in the track). Create a new folder within your track directory and name it "effect". Then, create a new folder within the effect folder named "StarRing". Within the "StarRing" folder, copy over the RKRace files, and rename these to "rk_StarRing.breff" and "rk_StarRing.breft". In BrawlCrate, make sure to rename both of these files (in the same way as renaming the MDL0 to "course"), to "rk_StarRing". Replace any textures with custom ones. For instance, if using a custom Blooper, locate and replace the "gessoSumi0" and "gessoSumi1" files, and replace them with your custom texture. Now, move onto editing the BREFF for custom colors/particle size. Remember to click "save subfile" after changing each subfile if using the BREFF Editor. It may be difficult to find what name corresponds to what effect. The particle field typically has a textureName field that you can cross reference with the BREFT file to help locate what effect it belong to. Notably, Lightning corresponds to "rk_thunder" and similarly named files. Once finished, you can remove any texture references in the BREFT that you have not customly created. Mario Kart Wii will default to the files in the Common.szs. Once done, make sure to add the StarRing object somewhere in your track, so that the effects are loaded.

Object-Specific Effects

Some effects are found within their own subfolder in the "effect" folder. These include the smoke from Wario's Gold Mine (truckChimSmk), or the splash when entering a liquid (pochaYogan). Using pochaYogan as an example, copy the "pochaYogan" folder from a custom track that has this object. Then edit the BREFF file using the BREFF Editor, and define any custom textures by replacing existing textures within the BREFT (do not delete any non-custom textures). Reminder that some objects include a BRRES file in the track directory as well. In the case of pochaYogan, in BrawlCrate, navigate to the materials section, and for each material, change the color found within the shader color block to the desired custom color.
