Hey guys and gals sorry if this is kind of a weird question, I am still very new to Houdini, just picking it up here an there when I have time. Anyways, Houdini masters, I have a scene in which many pieces of debris in an alembic archive react to the ground cracking in a dop. The aim here is to use the dop to first let the debris fall naturally onto the ground so there are no hovering objects, export the last frame of that part of the sim (with natural object positioning-no hovering) as a .bgeo, then bring that scene back into Houdini and start a new sim using the positions of the debris generated by the first. The problem I am encountering is that I cannot get the different debris to be considered different objects in the new scene I create for resuming the sim with the new positions. I am saving the .bgeo out with a dopimport node inside a dedicated geo node. Another method that occurred to me is writing the first sim out to disk (.sim), reading it back in, and using those positions to dictate the beginning of a separate dop sim… I am really not sure which is the more correct method to go with here. I'm sure positioning debris with a dop is a common task, so please, anyone with experience in this area, some guidance would be much appreciated to a total Houdini nub!

Thanks people!

Through some further experimentation I discovered the rbd packed geo node, this is essentially what I required to accomplish the result I am after and as a bonus it does not require me to split the different groups up into different parts to be added to the dop sim.
