I often use the mask extract tool, but for one reason it is now not working properly, it does not provide me any thickness when I hit extract regardless of how thick I make the settings, it just behaves as splitting/separating the meshes instead. I’m not sure if I’m missing something here.
My Mask Extract Settings
Check the scene inspector, are you sure you don’t have the extracted mesh there? I tested and it works but the new mesh remains under the mask, I understand you want the extracted mesh as positive for that you should change the extract closing action to “shell”
You’re right having it at fill instead of shell was the problem. Thank you!
