Harmony follows a set of rules as it evaluates the shapes. Familiarize yourself with these basic morphing rules before you start morphing.
NOTE Note that a morphing sequence can only be done on vector drawings. You cannot morph bitmap layers or Toon Boom bitmap drawings.
Here are a few tips about creating morphing sequences:
When learning about morphing, it is recommended that you use the Brush tool. You can use the Pencil line for simple closed shapes.
If you are using pencil lines, use Contour hints instead of Pencil hints. Use Pencil hint if you want the Pencil line to switch direction.
Flatten your drawing before starting a morphing sequence.
If you leave a dot, even the smallest one, it is possible that your morphing will create odd shapes. If the source line is closer to the dot than the destination line, the source line will morph into the dot and the destination line will disappear.
Use the same colour swatch between two drawings. You cannot morph between two different colour swatches even if they have the same RGB values. This can be turned to your advantage for complex morphing.
Similar shapes should have the same number of colour zones. This only applies to the number of zones and lines and not the number of points on a curve.
If a zone inside a larger zone on the source drawing ends up outside on the destination drawing, the morphing will fail.
For example, if you are morphing a face so it turns from the front to the side, the nose is located in the middle of the face on the source drawing. However if after morphing, the nose ends up outside or merged with the face profile line on the destination drawing, this will give undesirable results. You can avoid this by using morphing layers and splitting the nose on a separate layer.
