Blender - Vertex auto mask Node Group

Using vertex painting as material masks can be a great feature, but it's also a somewhat tedious process to paint in all the different channels onto your mesh, especially on large surfaces like landscapes.

With this small geometry node group for Blender you can simply create vertex masks in a single click with multiple options to define your desired outcome. This node removes all the necessary work of creating vertex paint masks and creates a procedural mask that can even be used in your desired game engine of choice.

• Supports 3 RGB colors in total, that are tweakable as you wish.
• Define the amount of each additional channel.
• Adjust scale of the pattern mask.
• Swap green and blue channels.
• Independent workflow of each channels
• Adjustable scaling and position.
• Smoothing options
• Opacity options

Install instructions:

• Go to edit and click on preferences

  

• Navigate to "File Paths" and scroll down to "Asset Libraries"
• If you already have a folder defined under "path" you can skip to the next step, otherwise create a folder somewhere on your PC and define the folder path inside those properties.

  

• Now drop the .blend file that is included in downloads into the folder that you created above.

Usage instructions:

• To use the node in your own blend project, open the Asset Browser, while making sure the drop down option, which is usually "Current File", is set to your library that you defined in your settings.
• Once that's done, you should be seeing an item that is called "Vertex auto mask".
• Drag and drop this into your Geometry nodes and connect your input geometry with the node group and connect the output into the output of your geometry node tree.
• Now you are free to play around with the sliders.

Future update plans:

• Chose pattern from multiple textures
• Input your own texture of choice. So you can input stuff like ambient occlusion bakes.
