I built a simple model of the Allianz stadium. The goal was to take the diamond pillows and slowly inflate them in an animation.

However, after creating clusters from the UV of the individual pillows (nurbs surfaces), I cannot get any transformations to occur perpendicular to the surface. I tried doing a locator with a aim&point constraint on the cluster but that didn't work..



Any suggestions? I need some simple method of inflatingabout 400 unique pillows...
Thanks in advance.
