Hello

I'm new to PDG on Unity.
In a very basic setup, just a simple box on an object_merge input inside an Hda.
I load my Hda with an Hda processor.
When I cook it on unity, I've this error message: part with type HAPI_PARTTYPE_INVALID is not supported for GeoSync.

I don't know why and what to do.

Please, I need your help.
Thanks in advance.
