The Pulse animation makes nodes progressively appear and then disappear. It can only be applied to nodes with the transparency attribute, e.g. structural models, visual models, meshes, and labels.

Adding the animation#

First, choose nodes that you want to progressively shown and hidden.

Then, double-click on the Pulse animation effect in the Animation panel of the Animator.

This animation has 5 keyframes:

  • between keyframes 1 and 2 the specified nodes will be fully transparent
  • between keyframes 2 and 3 the specified nodes will progressively appear decreasing their transparency
  • at the keyframe 3 the specified nodes will be fully opaque (no transparency)
  • between keyframes 3 and 4 the specified nodes will progressively disappear increasing their transparency
  • between keyframe 4 and 5 they will be fully transparent

Move the keyframes of the animation as needed.


You can always move the keyframes of the animation.


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