I am trying to animate a cell fractured rigid body wall being hit by an object and crumbling. I have created the Cell Fracture wall with a rigid body that is animated. When I initially press play the entire all fall infinitely as I would expect. I want the Wall to stay stationary until struct by another object. In the physics tab, I have checked the deactivation mark and the start deactivation checkbox. But when I press play the wall still falls.
I can get the expected result if I Start with an empty blend file but when I add this structure to an existing blend file it will not work. It's making me crazy. Any help would be greatly appreciated.
