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:
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.
