Modifying a Deformation Mesh

By default, the deformation mesh has three X,Y, and Z cells and one X, Y, and Z lattice. You can change the number of cells (1-3) or lattices (0-100).

NoteYou can only change the number of cells or lattices before you modify the parameters of the mesh. If you modify a parameter, for example, translate a tangent, you cannot change the number of cells or lattices.

To change the number of cells or lattices:

1. In the image window, select the mesh.
2. In the Deform menu, change the number of cells in the Cells X, Y, and Z fields. By default they are set to 3, 3, 3.
3. In the Lattices X, Y, and Z field, change the number of vertices.

   The cells or lattices are added to the deformation mesh.

4. To view the original mesh, enable Show Source.
5. Use the Outside button to apply the deformation outside of the mesh (enabled) or constrain the deformation within the mesh (disabled).

To select points:

1. From the Edit Mode box, select Move or Select.
2. Select the point(s):
   - To select a single point, click the point.
   - To select multiple points, hold the Shift key and click the points you want to select.
   - To select a range of points, hold the Ctrl key and draw a box around the points you want to select.
   - To add a range of points to a selection, hold Shift+Ctrl and draw a box around the points you want to add to the selection.

   When you move a point, all selected points also move.

   To transform a point on the mesh, drag it in the image window, or change the value in one of the X,Y or Z Translation fields.
