Features

• Create multiple vertex groups or a single weight-based group from a greyscale texture
• Support for existing textures or loading new ones
• Customizable settings for number of groups, minimum group size, and more
• Works with Blender 4.1.0 and above (and might work with earlier versions)

Installation

1. Download the init.py file and place it in a folder of your choice. (The default Blender addons folder is recommended.)
2. Open Blender and go to Edit > Preferences > Add-ons
3. Click "Install" and select the downloaded file
4. Enable the addon by checking the box next to "Mesh: Vertex Group by Texture"

Usage

1. Select a mesh object in Object mode
2. Go to Properties > Object Data Properties > Vertex Groups
3. Click on "Create Vertex Groups from Texture"
4. Choose your settings:
   • Texture Source: Use an existing texture or load a new one
   • Use as Weights: Create a single weight-based group or multiple groups
   • Normalize Weights: Set the weights range to between 0.0 and 1.0
   • Number of Groups: How many vertex groups to create (if not using weights)
   • Minimum Group Size: Smallest number of vertices to form a group
   • Base Group Name: Prefix for your vertex group names
5. Click "OK" to generate the vertex groups

Requirements

• Blender 4.1.0 or higher (will probably work in earlier versions, too)
• Active UV map on the target mesh
