User Interface Introduction for FFD Editor

1. Load and Save FFD Presets

   In this section, you can:

   • Save current shape of FFD lattice as a preset file (*.ctFFDPreset).
   • Load a saved presets (*.ctFFDPreset) of the shape of the FFD lattice.
2. Additive

   Incrementally blend preset shape to the current FFD lattice.
   

3. Bone Display

   For setting the appearance of the bones.
   

   • Show Bone: Show or hide the bones.
   • Body/Face drop-down list: Switch to display face or body bones (not available in the FFD Editor in Stage mode).

   • Opacity: Set the opacity of the bones.
   • Connect: Show/hide the connecting triangles between bones.

     Connect: activated	Connect: deactivated

4. Preset Libraries

   Switch to different libraries to apply FFD presets by clicking on the one desired.

5. RTS for Control Points

   You can change the shape of the lattice by directly transform the selected control points on viewport, or by typing values into the Move, Rotate and Scale numeric fields.

6. Mirror

   Either horizontally or vertically mirror the selected control points.

   • Horizontal:
   • Vertical:
7. Align

   These buttons can be used to align selected control points.

8. Intensity

   Click the plus or minus buttons to increase or decrease the strength of the FFD lattice.

9. Flip

   Click the Horizontally or Vertically buttons to flip the lattice.

   • Horizontally:
   • Vertically:
10. Average

    For redistributing the lattice box based by the four corner control points.

11. Align to Root

    When the lattice box is overly deformed, the sprite can deviate from the pivot point by a great distance. By clicking this button, you can move the entire lattice and sprite back to the pivot without changing the shape.

12. Reset

    • Reset Selected: Resets the position of the selected control points.
      1. Apply any of the FFD presets to distort the prop.

      3. Click the Reset Selected button.
         
    • Reset All: To reset the position of all control points. As in the previous example, the lattice shape will be restored its original rectangular structure.
      
13. Set Key

    Add an FFD key of the shape of the current lattice. It is useful when you want to extract a specific shape of the deformation.
