In the discussion thread, I already shared my idea for replacing the Musgrave node with a Noise Texture node.
The same issue occurs in the Exclusion Group, which also doesn’t work in Blender 4.x the way it’s shown in the video.

Below is my solution using a Noise Texture node, as required in Blender 4.x, for the Exclusion Group.

I also made a small change because the setup shown in the video using a Subtract node didn’t work as expected in my version. Instead, I used two NOT nodes combined with an AND node, which successfully creates the two ring areas and works just like in the video.
