Creating Mods

Start a New Project

A fresh project starts with an empty folder structure, default manifest template, and auto-generated mod UUID.

Configure Basic Information

Edit the manifest in the right panel to set your mod's identity:

{
  "Version": 1,
  "Guid": "xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx",
  "Name": "Your Awesome Mod",
  "Description": "A brief description of what your mod does",
  "IconPath": ""
}

Add Files and Set Icon

For mods without configurable options, add files directly to the root:

1. Right-click in the file explorer area
2. Select Add Files and choose your .patch_0, .gpu_resources, and .stream files
3. Optionally, right-click and Set Mod Icon to add a thumbnail (PNG, JPEG, or WebP, 256x256 or 512x512 pixels)

Create Options and Sub-Options

For mods with user-selectable variants:

Adding Options:

1. Right-click in the file explorer > Add Folder
2. Rename the folder to something meaningful (e.g., "High Quality", "Low Quality")
3. Right-click the folder > Add Files to populate it with patch files

Adding Sub-Options:

1. Right-click an option folder > Add Sub Folder
2. Rename and add files as needed

The manifest automatically reflects your folder structure:

{
  "Options": [
    {
      "Name": "Weapon Skins",
      "SubOptions": [
        { "Name": "Gold", "Include": ["Weapon Skins/Gold"] },
        { "Name": "Chrome", "Include": ["Weapon Skins/Chrome"] }
      ]
    }
  ]
}

Set Preview Images and Descriptions

Help users visualize and understand each option:

Preview Images:

• Right-click an option folder > Set Option Image
• Right-click a sub-option folder > Set Sub-Option Image

Descriptions: Add them directly in the manifest editor:

{
  "Options": [
    {
      "Name": "High Quality",
      "Description": "4K textures for maximum visual quality.",
      "Include": ["High Quality"],
      "Image": "High Quality/preview.png"
    }
  ]
}

Press Ctrl + S to save manifest changes.

1. Click the Build button
2. Choose an output location
3. The mod pack folder is generated:
