Editing Keyframes

Frame-by-frame animation in a Voxel Movie is built from Voxel Keyframes.

A Voxel Keyframe is a Voxel Layer with an additional Duration property that defines how long it is shown in the animation.

Keyframe Editing Basics

Voxel Movies are simpler than Voxel Scenes and are focused on editing one keyframe at a time.

Important differences:

• Voxel Keyframes only
  Voxel Movies can only contain Voxel Keyframes.

• No parenting, rotation, or scaling
  Keyframes are edited as independent voxel objects.

• One editable keyframe at a time
  Only the current keyframe is shown for editing.

• Same voxel editing tools
  Keyframes are edited with the same voxel tools used elsewhere in Foxel.

Selecting a Keyframe

You can select the keyframe you want to edit in two ways:

• Hierarchy
  Select the keyframe in the Hierarchy.

• Timeline
  Move to the frame you want in the Timeline. Foxel selects the displayed keyframe automatically.

Adding a Keyframe

To add a new keyframe:

• click Add Voxel Keyframe below the Hierarchy, or
• use Object > Add Voxel Keyframe.

The new keyframe is inserted after the current keyframe and starts as a copy of it.

Setting the Duration

The duration of a keyframe defines how many frames it is displayed.

You can change the duration in two ways:

• Inspector
  Select the keyframe and edit its Duration property in the Inspector.

• Menu Command
  Use Object > Set Duration.

Editing the Keyframe Content

Once a keyframe is selected, you can edit its voxel content directly with the normal voxel editing tools.

A common workflow is:

1. Select or create a keyframe.
2. Adjust its duration.
3. Edit its voxel content.
4. Move to another frame or keyframe and continue.
