Hello Houdini Community!

I have a big problem with a sim for a project. I fracture a Glas with the voronoi fracture configure object with the metaball and manget force function. My problem is I can't write out a alambic file of it. If I use the ROP alembic output node with the dopimport output of the glas the glas disapears exactly in the moment of the fracturing in the dop network. What is wrong?
