Know Of Any Good Structure Fracture Tool?

I have been trying to figure out the best way to break things.

For example, if I have a model of a pillar that gets smashed by a huge monster.
I want break it into a lot of chunks and run it through Bullet Physics.
Up till now I still have not been able to find fracturing tool that is
powerful enough to handle things more complex than a cube. The
cell addon in Blender can’t even handle cubes half the time. I’ve only
been able to get good results by applying it to a plane that has a
solidify modifier on it.

What do people in hollywood use when then break complex geometry
like huge building models?

This may help… You probably want to use this constraint add on

there are 2 addon for this
see the frature cell addon

and also it is part of the new rigid body tool!
