CodeWalker is a tool that allows you to browse, analyze, and modify the 3D game world. It will also allow us to create environment mods. It offers an interactive real-time map, with features such as:

• 3D exploration of the game map
• Loading and editing map files (YMAP, YBN, YDR, etc.)
• Creation and modification of scenes, objects, and scripts
• Analysis of collisions, entities, roads, paths
• Visualization of game data (occlusion, zones, volumes, etc.)

Download Code Walker

1. Download the zip file containing CodeWalker from here, the official link from the official Github repo of the project.
2. Extract the downloaded zip folder 1cfcd8-CodeWalker30_dev46 to the desired location.

The folder contains several .exe files

1. CodeWalker.exe is the map editor.
2. CodeWalker RPF Explorer.exe is a file explorer.
3. CodeWalker Vehicle Viewer.exe is the vehicle explorer.
4. CodeWalker Ped Viewer.exe is the humanoid explorer.

The first time you run the software, it will ask you to select the path of the game files. If you have already installed Open IV, the software will be able to automatically detect the game folder.

Once this step is completed, the software should take some time to load all the data

To get a head start on content creation, you will need to add a file to the root of the GTA V game nametables.rpf.

1. Join the CodeWalker Discord server
2. Go to the #tips-documentation channel and look for the latest nametables.rpf file, download it (as of the writing of this tutorial, the latest file was this one).
3. Run CodeWalker RPF Explorer.exe and add the previously downloaded file to the root of the GTA V folder.
