I have just started working with houdini 11 and am trying to use the make break tool.

The tool works like it should but I am having a few issues that maybe someone could help me out with. First I would like to add gravity and wind to only the objects that have been broken. So when my magnet force goes through the object I want the part that has not been effected to stay still while the other pieces are blown off. I tried to look in the details view to see what was going on with the naming convention but it seems to be un-ordered.(as I have 12 boxes but there are 13 in the details view)

The other issue I am having is with collision. The make break objects are falling through the static object set up in the scene. This happens for about two-three frames before the object realizes its colliding and it gets stuck. I have ramped up my sub steps, collision passes, volume, divisions, turned on triangulation… nothing seems to solve the problem.

If anyone has some ideas on how to solve either of the problems I would greatly appreciate it.
