Ok, I was just looking at the manual after reading your reply. So if I'm understanding it correctly, freeze/unfreeze is simply another word for mask/unmask like in Photoshop, etc?

Hello, I'm a new 3D coat user and I'm currently painting a Maya UV'ed model imported as OBJ. Whenever I hold down the left Ctrl and double click a layer. I get an animated checkered pattern over my model that looks like the image below. There's no way to remove or undo the checkered pattern but to reload the project. Can someone explain to me what this is and how to switch it off without closing and re-opening the project.
