here’s the sim and render from the file i previously posted.
notice how due to the fact that all fragments are placed into the inactive objects list this allows for a chain reaction and the bottom and top parts of the column are also affected and fall due to gravity.
because as soon as the pieces are touched by the “wing” they bump into each other sending each piece into the impact list.
I notice a lot of the column breaking tests don’t have this happening, and i believe this adds realism.
because the tops shouldn’t just be hanging in mid air.
be sure when you sim with interactive demolition on that your using the Bake animation button and not just the regular sim button or interactive demo does not work.
This is the outcome from the previously posted file.
All i did was open it and hit bake simulation.

… thanks for all the help you guys, would of never got this far without ya:beer:
