Hi!  
I am doing some fracture with the “Cell fracture” and “Fracture tools” add ons. I want a bottle to break from a bullet hitting it on the middle. When I do this the whole bottle is being fractured. Is there a way to “delay” the fracture of the top and bottom parts of the bottle, so that its just the middle part that falls apart on collision??

Thanks!!! 😃

I think you do it with weight painting and linking the weights to the timing. See this tutorial. He makes a fracture wave travel up an object from the bottom.
