3D-Coat has symmetry across multiple planes, even simultaneously. It also works radially if you need to work radially. To use symmetry, either go to the Symmetry Menu or press the S key, and toggle it on (or off if you don’t want to use it). Symmetry works in almost all of the Rooms. While it is more or less identical in functionality between the Paint and Sculpt Rooms, it is also a little different. The Retopo Room not only uses Symmetry Mode, but also Virtual Symmetry, which we’ll discuss below.
First let’s look at the Symmetry panel.
Toggles Symmetry on/off.
Show Symmetry Plane
Toggles only the visibility of the symmetry plane.
- Mirror: Paint, Sculpt or Retopologize across a plane, or multiple planes.
- Radial Symmetry: Paint, Sculpt or Retopologize radially, with as many radial slices as need. Can create radially and across a symmetry plane simultaneously for more complex procedures if needed. Creates radial objects before the mirrored symmetry.
- Radial Mirror: Paint, Sculpt or Retologize across a symmetry plane. A hybrid of Mirror and Radial modes. Creates the radial objects after the mirrored symmetry plane.
X,Y, Z Toggles
Toggles the respective plane on/off for symmetry.
Allows you to specify what the global center is for the symmetry plane, can be either true Global Space, Local Space (to the Objects center) and General Case Axis, which is a customizeable center.
Virtual Symmetry (Retopo Room)
An additional mode of symmetry for the Retopo Room, this allows you to create virtual symmetry so you can see what your Retopo Object will look like symmetrically. A “real” workable mesh can be created from virtual symmetry as well, but also be aware that if you already have a symmetrical Retopo Object, turning on Virtual Symmetry will effectively “double-up” on the amount of polygons visible, even if the geometry is virtual.
Also note that if your mesh has symmetrical geometry in the Retopo Room, than turning Symmetry Mode on will create actual, editable geometry on top of the already existing geometry. So avoid using symmetry with that kind of mesh, in the Retopo Room.
