 So you don't know how to use Inset, not a problem. FaceInset allows you to left click to create incisions on a polygon. If you mess with the size and left click it will try and keep the size the same as when you last adjust it. If you tap alt you'll be able to change the color of the new polygroups. And if you hold alt before left click and you can click and drag specific positions you want to apply the Inset to. And while holding alt left click again to remove a selection. Center and border gives you a new center and border. Border just gives you a border. And center only gives you the middle. But each poly will apply one action to each face individually. But if you have this set to region it will apply one action to the entire region. EquidistantTries tries to keep all the edges the same border and size. Standard is more flexible with the border sizes. And legacy only works if you have this set to each poly. No size limit means you can shrink and grow them to any size. Default size limit means they can't get any smaller than this. And if you want to manually set the limit to how small they can be do that over here. Default snap is usually what you need but if you find yourself getting some weird triangles try the custom setting and kicking this all the way up. And if you're lucky it might get rid of them. Hope that helps and as always I hope you have a fantastic day and I'll see you around.
