 So you don't know what islands do, not a problem. This just means it'll apply actions to every face that is attached to the object that you clicked. So here you see we have two separate objects. There's a small object floating on the top and the main body at the bottom. Because they're separated, they're treated as two different islands. So if I left click at the bottom, that's where the actions get applied. If I left click at the top, then that is where the actions get applied instead. Hope that helps. And as always, I hope you have a fantastic day and I'll see you around.
