Magnet Distance
The default node for selecting and manipulating the grid is a Magnet node. The magnet is
represented in the viewer by a circle around the mouse pointer. The Magnet Distance slider
controls how large the region of effect for the magnet is, as in the size of the circle. Drag on the
grid and any vertex within the range of the slider moves.
To increase the size of the magnet, increase the value of this slider. Alternately, adjust the size
of the magnet by holding down the D key while dragging the mouse.
Magnet Strength
The Magnet Strength slider increases or decreases the falloff of the magnet cursor’s effect. At a
setting of 0.0, the magnetic cursor has no effect, and vertices do not move at all. As the values
increase, the magnet causes a greater range of motion in the selected vertices. Use smaller
values for a more sensitive adjustment and larger values for broad-sweeping changes
to the grid.
X and Y Grid Size
The X and Y Grid Size sliders control the number of divisions in the grid. Where the X and Y
divisions intersect, a control vertex is created.
Be aware that changing either of these controls after applying changes in the grid resets the
entire grid. Set the X and Y grid sizes to the appropriate resolution before making detailed
adjustments to the grid.
Subdivision Level
The Subdivision Level determines how many subdivisions there are between each set of
divisions. Subdivisions do not generate vertices at intersections. The more subdivisions, the
smoother the deformation is likely to be, but the slower it is to render.
Center
The Center coordinates determine the exact center of the grid. The onscreen Center control is
invisible while editing the grid. Select the Edit Rect mode, and the grid center becomes visible
and available for editing.
Use the Center control to move the grid through a scene without affecting the animation
applied to the individual vertices. For example, while deforming lips, track the motion of the
face with a Tracker, and connect the grid center to the Tracker. This matches the grid with slight
movements of the head while focusing on the deformation of the lips.
Angle
This Angle control rotates the entire grid.
Size
The Size control increases or decreases the scale of the grid.
Edit Buttons
There are four edit modes available, each of which can be selected by clicking on the
appropriate button.
Edit None
Set the grid to Edit None mode to disable the display of all onscreen controls.
Edit Grid
The Edit Grid mode is the default mode. While this mode is enabled, the grid is drawn in the
viewer, and the control vertices of the grid can be manipulated directly.
