KCL Editing

KCL is used for collision for most Nintendo games for Wii U and Switch.

Requirements:

• this tool.
• A 3D modeling program that can export as .obj

For this tutorial i will create a basic example using blender.

Export your model as a .obj and make sure it's triangulated in the settings.

Now open Switch Toolbox.

You can create new ones from the (File - New From File) menu.

Alternatively, you can open an existing KCL, and right click, then replace it.

This will open a file dialog, so select your exported obj file. Then a window will pop up. The material values will vary depending on the game.

Select the game you want to edit, or choose other if it is not there.

When the game is selected, you can check the preset editor option which will allow you to view collision presets.

Note if you want to add/edit these, you can do so with this guide

Then click "Apply". Now your collision is imported!

Lastly File - Save to save your new collision.
