Activating RBD fracture pieces and using SOP point velocities

[Mike_RB]

I have 3 pieces in an RBD fracture object. I have point velocities set in the SOP that work well when I use the 'inherit velocity from point velocity' flag.

What I want to do now is trigger them one at a time. I tried using a 'group' SOP and an animated box to make a changing active group and then using the 'RBD keyframe active' node to activate them. This sort of works if I start them inactive, except all I can do is get them to fall once the become part of the group. Unless they become active on the creation frame of the fracture object I lose the point velocities. Is there a better way to do this?

In the end I'd like to be able to have a path of 50 of these object that I activate following the animation of something else, and have them once activated use the point velocities on thier first frame.

Thanks.
