Help with RigidBody

Hey,

I have a simple Rigidbody simulation and I was wondering if I could use a Force Field to effect the simulation. I have a several objects stacked to make a wall and right now, my boxes just fall straight down. I would like to create the effect of a shotgun blast hitting a wall and exploding the pieces.

It seems that Force Fields only effect dynamics. If I can’t use a force field, how can I manipulate a force hitting the wall pieces?

Thanks,

Wes
