 So you love creasing. Not a problem. Face crease lets you quickly put creases where you left click. For example, if you have targets set to polygroup island, meaning a group of faces that are all the same color, all sides literally just means it will crease every edge connected to that group. Generally long sides tries to pick all the edges that go horizontal and short sides tries to get all the edges that go vertical, but sometimes it gives weird results, so be careful. All faces means every face that is connected to your target. Polygroup border specifies that only the border of the color group gets targeted, and polygroup inner means everything except the border of the color group gets targeted. All transitions just means it won't distinguish between edges based on their angles. Shallow transitions means any edge that is bent at an angle smaller than this number will not be affected. So if we set this to 100 and left click this edge will be creased because it has a 90 degree angle which is less than 100, but if we set this to 85 because this is a 90 degree angle it will not be affected. Sharp is the opposite, it means if we set this to 80 it means that all edges with angles less than 80 degrees will not be affected. All targets just means that every edge that is connected to the group will get creased. Outer targets means only the outer edge of the group will get affected, and inner targets means only the edges not on the borders will get creased, and outer and inner have to do with deleted faces. All sides just sets to everything, if you set to outer, only edges bordering a deleted face will be selected. If it's set to inner, only edges that are not bordering a deleted face will be selected. Anyway I hope that helps and as always I hope you have a fantastic day and I'll see you around.
