I've got a simple animation idea. Basically a bunch of flat planes extend into a city-like layout. This is I get when I manually scale (using 3d cursor) the buildings:

As you can see, they build from the bottom up, which is what I want.

When keyframing this, instead of scaling from the bottom (or 3d cursor), they scale from the center of each pillar individually:

How do I keyframe scaling from the 3D cursor? (Or, if possible, specifically the bottom of the pillars?) I did research and using 3D cursor seemed to be the only way to scale it from the bottom instead of the center.

  • $\begingroup$ That is weird, what i would do is use shape keys and edit the pillars themselves so they always go from the ground up, instead of relying on the object scale $\endgroup$ – Unnamed Sentient Being Oct 5 '16 at 1:13

You have to keyframe both location and scale, if you want to scale in relation to the 3D cursor.

Key Frame

Since the object's pivot points are aligned with their geometric center they are technically moving, since the center position shifts up during animation.

Scale Animation

Ideally though you should position all your objects center aligned with their bottom faces though.
