This is the way. Thank you!

If you want to export from Geometry level you need to enable Hierarchy Path in ROP_FBX.
That means we need to have that "path" Attribute on Primitives been created.
As variant A, use Asseble SOP to do the job

But I prefer B => manual creation of that path attribute.

And to get nice looking semi automated paths, in Attribute Create for String I use expression `opname('..') + '/' + opinput('.', 0)` to combine Object name and Previous Node Name.
In FBX ROP I use $HIP/`opname("..")`.fbx to export in same directory as my project file and name it as Object Named

The issue I run into, and what I think the OP is pointing out, is that when I want to bake the asset, it bakes as two separate meshes. Hektor, what you seem to be pointing to is when it is still being used as a Houdini Asset.
