If I import an obj fie that has multiple objects and directly export (with zero changes) to a Geometry ROP as a Obj I lose the hierarchy when I take it back into other packages, it is from that point one solid object. I DO NOT WANT TO EXPORT AS ANY OTHER FILE TYPE. OBJ ONLY. Can anyone help?

I'm not sure .obj can hold such information, it's a relative simplistic geometry format
it can hold named poly groups that would come in other packages as flat objects
or do you have an example of .obj file that contains hierarchy that you exported from another package and trying to match?

Okay attached so attached is two screen shots,
1. What we export from Cinema then import into Houdini
2. What we export from Houdini back into Cinema
"two_objects.obj" is directly from Cinema with a hierarchy.
"two_objects_Exported.obj" is directly exported from Houdini without a hierarchy.

While obj supports tagging of groups and objects within one file, Houdini does not support exporting multiple objects in one obj export.

Wow that sounds like a very basic level thing that Houdini should support.
