In the documentation you link to, the section with GHOST says (highlight mine):
And this is the issue with their models. LDCad outputs the stuff between SAVE and RETRIEVE without any modification, so other viewers will simply also render all the stuff in those sections.
Now I see, I actually implement nested BUFXCHG meaning it will also work on submodels.
To this end I keep track of two visibility flags one for visibility as seen from the last step (submodel state) and one for the current step of the model you're working on.
This is a fairly easy fix and prevents littering all those GHOST meta's imho.
But if you want to use the ghost tag in your instructions you can use the newly added "toggle ghosted lines" macro of 1.6d, it's in the scripts/mlcad menu.
