Set background

The Set background animation sets the background between two frames. You can also display background images such as presentation slides. When setting an image as a background you choose whether the image should be fully contained in the viewport or cover it (might be cropped by the largest side).

The presentation will automatically perform interpolations between backgrounds when multiple backgrounds are present. You may control the interpolation using the easing curve in the Inspector.

Adding the animation

Double-click on the Set background animation effect in the Animation panel of the Animator or in the Animation menu. The begin keyframe will be placed at the current frame. Move the keyframes of the animation as needed.

Note: You can always move the keyframes of the animation.

The animation has 2 keyframes:

  • at the keyframe 1 the specified background will be set
  • after the keyframe 2, if there is another Set background animation specified then the presentation will perform interpolations between backgrounds


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