About Form Animation (FA)

(Updated 09/09/2019)

This page describes the Form Animation (FA) feature.

What is form animation?

Form animation is a convenient function for video production that allows you to directly edit the model form on the animation editing timeline without using parameters.

You can freely transform the object without affecting the model data.
You can interact with objects directly on the timeline to keyframe form animations.
It is also possible to fine-tune the timing with the time remap function.

Form animation cannot be exported to the SDK because it is a function dedicated to the target “video”.
Be careful when creating data for embedding.
(The contents of the form edit are not reflected even when checking the movement in the physics calculation / scene blend setting.)


Open form animation view

Load the can3 file and click the [Start Form Editing] button on the model track.

The form animation view opens.

Saving form animation editing data

The edited data of the form animation is saved in can3.
If you accidentally close the form animation view, the data will be preserved if you open the animation view.
(If you press the form edit start button again, the form animation view will open and the key will be displayed.)

However, changing the display state or lock state of the part affects the model data, so
If you want to keep those changes in the form animation view, you need to save the model data as well.


Precautions when editing model data

Change the structure of an object

Changing the structure of the model data to which the form animation is applied may affect the form.


After the change, recovery will be performed automatically, but since the structure will change, the shape may be slightly different, so check the changed part.
(Please note that you will not be able to undo the previous operation of the animation at that time.)

  Change before After change
Mesh condition

Model data will be automatically recovered when changes are made in the following cases.
• Mesh reorganization of ArtMesh
• Change the number of divisions in the warp deformer conversion
• ArtPath control points, etc.


Change the parent-child relationship of the deformer

Basically, it is recommended that you do not change the parent-child relationship of the deformer after editing the form,
If you need to modify the model data, please note the following points.

When the form is edited on the object (A) with the parent deformer (D1) set, if the model data is modified and the parent deformer of the object (A) is changed to (D2), the form collapses.
This problem occurs only in [Adjustment mode 1].

To work around this issue, display the following warning if the direct parent deformer changes and discard the form edit information.
(Please note that you will not be able to undo the previous operation of the animation at that time.)

The problem does not occur unless the direct parent deformer of the object to which the form edit is applied has been replaced.


Example of foam collapse
When adding a warp deformer to an ArtMesh that has been edited from a form

 No collapse  There is a collapse
 If a warp deformer is set for the immediate parent, the form will not collapse even if the warp deformer is set for the parent above it.  If you set a new warp deformer with the warp deformer of the direct parent and the parent of the ArtMesh is changed, the form will collapse.

The above is an example of the warp deformer of the direct parent of ArtMesh,
The same is true for the deformer's direct parent deformer.
