Stacker Window


The Stacker is our special keyframe manager, inspired by traditional animation X-Sheet (which is by far the best tool to manage keyframes). It works in a complementary way with the TimeBar.

Replicating exactly an X-Sheet would not have been pertinent as 3D environment has its own needs and constraints. That is why we imagined something different, something that would mix the "best of the two worlds" (2D and 3D).


Keyframes

Inside the Stacker, a keyframe looks like this:  

  • Keyframes are displayed in the center, listed vertically and numbered.
  • Keyframes have their time position (global time) on the left side. You may edit this time by LMB double-clicking on it.
  • Keyframes have timing between keyframes on the right side. You may edit this time by LMB double-clicking on it.
  • keyframes can be moved by drag'n'drop.
  • If you press Ctrl button during the drag'n'drop it duplicates the selected keyframes 
  • Keyframes can be flagged as "Extreme" or "Breakdown" by RMB click menu.


Keyframe RMB Menu

By RMB clicking on a keyframe you open the Keyframe Menu:

  • Mark the selected keyframes as "extreme" ().
  • Mark the selected keyframes as "breakdown" ().
  • Remove marks from selected keyframes.
  • Remove all marks.

Stacker features

Create Key: Add a key after the current keyframe with a default timing. After creation, the new key is automatically selected.

Delete Key: Remove the current keyframe(s) selection and its timing.

Display Prev. Ghost: Show previous key or frame of the Stacker as ghost. 

Display Next Ghost: Show next key or frame of the Stacker as ghost.


Loop Mode: Insert an automatic loop key to simplify cycle animation workflow. The loop key is positioned at the end of the animation and can't be edited as it always mimics the first key (even if it is modified afterward) ().

Animation curves "pre" and "post" loop mode are automatically modified.

 Quick Select Keys: Select all, first half or second half of keyframes. 

Timings amount: This field displays the total time amount for the currently selected keyframes. When you edit it, selected keyframes' timings will be scaled to match the value you entered (as best as possible).


Audio Stacker

The Stacker is also used to manage Audio Clips

To create an audio layer, you will need to go in the mixer window and use the "Create Audio Layer" button


 Add Audio Clip : Open the explorer so you can pick an audio file.

 Delete Audio Clip : Removes the current audio clip(s) selection and its timing. If you delete the last audio clip in the stacker/timebar, the audio layer will be removed as well


Inside the Stacker, audio clips looks like this:
 

  • audio clips are displayed in the center, listed vertically.
  • audio clips have their time position (global time) on the left side. You may edit this time by LMB double-clicking on it.
  • audio clips length are displayed on the right side. You cannot edit this time since we do not allow to extend/compress a clip timing yet.
  • audio clips can be moved by drag'n'drop.
  • If you press Ctrl button during the drag'n'drop it duplicates the selected clips
