I've unpacked the geo and converted it, When I try to selected and delete or group the polys I get the error "Attempt to access and object that no longer exists in Houdini" is there a way to delete individual polygons or groups? Thanks

I believe you have to do it before unpacking and converting. Then you will have your groups and whatnot intact.

So I've exported an alembic from Maya, and brought it into houdini. I want to edit individual polygons inside the alembic. When I unpack and convert and then try to select the polygons I want to delete I get the error.

so I actually just figured out that if I do the same thing with an alembic exported from houdini, it works. The problem is that my alembic is exported from maya. Does anyone know what setting I'm missing in Maya to get this to work? Thanks

when exporting from Maya, enable Write Face Sets.

Then in H, Alembic, Load As Unpack Alembic.....(or you could also manually add a separate unpack node)

Is this in the import options? or the options after importing?

Those are in the maya export options. 
Either way if you unpack the alembic you should be able to delete the geo.

Ok so I selected this setting and after importing it is still not working.

you were inside the Alembic archive, just obj merge your geo into a new file obj so you can manipulate the geo.
