The Hidden animation makes nodes hidden between two keyframes. This is done via the visibility of nodes and not via their transparency.

Adding the animation#

First, choose nodes that you want to be hidden.

Then, double-click on the Hidden animation effect in the Animation panel of the Animator. The begin keyframe will be set at the current frame. Move the keyframes of the animation as needed.


You can always move the keyframes of the animation.


In the movie we use the Animation menu which is no longer present in SAMSON. You can access all animations via the Animation panel in the Animator (1) and all presentation actions via the Animator's controls.

  1. Interface > Animator, , : Ctrl+7, : Cmd+7


You can change how the parameters are interpolated between the frames by modifying the Easing curve.
