KMP3D is a SketchUp plugin made by zatchi that functions as a 3D interface for Mario Kart Wii's KMP files, which deal with coordinate information, such as check points, item routes or respawn point positions. Points are represented using either spheres or vectors, depending on the point type. Additionally, it supports AREA visualization and previewing opening and replay cameras.


  • Beaglebark413, for the item box model used as a placeholder for other objects.




Note: If you have a previous version of KMP3D (v3.0 or lower), make sure to disable/uninstall the old extension before installing a newer version. Failure to do so will result in a loading error.

For SketchUp 2013-2016

  1. Download the .rbz file.
  2. In SketchUp, go to Window -> Preferences -> Extensions -> Install Extension..., and select the file.

For SketchUp 2017+

  1. Download the .rbz file.
  2. In SketchUp, go to Window -> Extension Manager -> Install Extension..., and select the file.

For SketchUp 6-8

  1. Download the .rbz file.
  2. Rename the .rbz extension to .zip.
  3. Extract the contents of the folder into the Plugins folder in SketchUp's Program Files for Windows, or Applications folder for Mac.


Adding and editing points

  • Activate the tool and click anywhere on the model to place points. In the case of vectors and checkpoints, additional steps are required to correctly place the orientation.
  • Editing settings can be done through editing the table. Toggling the selection of points can be done by selecting the ID number on the row for the point.
  • Points can also be removed by clicking the "x" on the end of the table.

Group editing

  • Groups can be edited, selected, and deleted like points under the Group Settings tab.
  • Certain settings, such as Next Group(s) (found in ENPH, ITPH, and CKPH), are comma-separated lists of IDs to the next group.
  • Object types are also treated like groups, with each group setting denoting the object's name. You can import custom models to visualize how they would be in-game, so long as it is converted to the SKP format first. However, a library of object SKPs are included and used automatically, depending on the object ID.

Importing and exporting

  • Go under Plugins (or Extensions, depending on the version) -> KMP3D. This is where you will find the options to import and export KMP files, as well as import KCL files.
  • If overwriting a file, the KMP will be merged such that sections will only be overwritten if they have data in them.
  • For importing KMPs, make sure to activate the tool to view the points, as everything is hidden by default.
