I'm an MC animator, and I am a noob. I want to create an animation where the world deletes, and the character falls into the main grid thing.
I use a MAC, and Blender 2.79b.
The other answer (by @FranciscoArleo) assumes you are using physics to animate the fall, and is the simplest solution if this is the case.
If you are hand animating then the scaling trick is not necessary, instead you can keyframe render visibility in the outliner by toggling the camera icon next to the object, and then right-clicking the camera icon and selecting insert keyframe.
