setting an animation on top of a background

I’m working on a bouncing ball animation and I have my background as a separate frame but when i play the animation, the bouncing ball goes over the background. How do I set the background to stay as the background?

If your background resides on a Drawing layer, move it back on the Z Axis through the Layer Properties window.

You can open a window for the top or side view to be certain to move it enough for the animated ball’s path.

With either additional windows you can manually grab the layer once highlighted and move it as well.

on a separate Layer below your animation with the bouncing ball Layer and as always remember to right click your background Layer and select extend exposure to the length of your animation
