Face

element face faces are the faces that make up the mesh, and moving or editing a face affects the elements associated with it face icon select you can view the properties of a face by pressing the keyboard shortcut shift+3 , or by using the buttons at the top of the scene face element group properties these are the properties that are displayed for the element group when a face is selected control preserve uvs preserve uvs is a feature that maintains the proportional relationship of uv coordinates when moving previously unwrapped elements this means that as you move an element in 3d space, its uvs are automatically adjusted to follow the movement proportionally, preserving their original layout relative to the geometry how to use 1 enable preserve uvs by checking the option 2 move the element 3 the uvs will be updated accordingly note the overlay in the uv editor will refresh only after the mouse cursor moves over the editor select property that allows you to set how the face is selected backface select allows you to set whether opposite faces are selected face backface select off when the backface select property is off, opposite faces are not selected face backface select on when the backface select property is on, opposite faces will be selected as well camera based select this property selects only the currently visible face based on the camera face camera based select off when the camera based select property is off, faces hidden by the camera are also selected face camera based select on when the camera based select property is on, faces that are hidden by the camera are not selected soft select this property selects faces in the scene that are adjacent to the selected face based on their weight the selected faces and the range you set based on the weight are colored, usually a soft circle soft selection properties that use soft selection face soft selection soft selection curve a graph like property that determines the shape of the soft selection tap the graph next to the soft selection curve property to edit it face soft selection curve example of curve shape examples of how the selection shape changes depending on the curve shape example 1 face soft selection curve example 1 example 2 face soft selection curve example 2 soft selection range a property that sets the range over which the soft selection is applied from the selected face in unity, 1m = 1 0 , so for 0 5 , it will select up to 50cm from the selected face face soft selection range extrude option properties that allow you to choose how the face is extruded when using the extrude tool face extrude option the extrude tool can be used to extrude or extrude faces using the keyboard shortcut shift+click drag gizmo default this is the default property for the extrude tool , which causes the extrude tool to run based on the gizmo face gizmo default individual normal the extrude tool will run on an individual face by face basis , aligned with the face's normal direction face individual normal note the difference with the vertex normal property is that for individual normal, the extrude tool is run for each face, so the selected faces are all extruded or pushed apart vertex normal the extrude tool is run in the normal direction of the faces face vertex normal average normal runs the extrude tool in the average normal direction of the selected faces face average normal distance a property that is displayed when an element is moved indicates the distance traveled face distance smoothing group this is a property that allows you to manage faces as a group, making them appear to be connected or disconnected from each other face smoothing group face smoothing group example a group of selected faces will smoothly connect surfaces, while other groups will appear disconnected tip proper use of the smoothing group property can help you achieve smooth surfaces with a small number of faces, and can help with optimization auto smooth this property automatically sets a smoothing group between selected faces clear this property resets all currently set smoothing groups face smoothing group clear selected smoothing group this property selects the face set to the group when the button corresponding to the group is pressed tip in addition to smoothing, the selected smoothing group property can also be used to manage complex models in groups, as it makes it easy to select faces selected smoothing group example since a single face can have more than one group, you can also select them as shown in the example below face selected smoothing group example 1 face selected smoothing group example 2
