[Gabriel Vallecillo] ” I apply nitroblast, remove the floor and the broken pieces of the wall continue to fall onto some surface.”
You probably baked the animation, which would need to be cleared to allow for new dynamics with the floor removed.

To activate dust enter something in the “Name” window, click “Create,” and NitroBlast will add an X-PyroCluster object to the project and add it to the “Particle Group” window. Select “Enable” to activate.
