This way of doing it is not ideal as there is a lot of duplicate code. I'd think that having this functionality in ARMarker would make it cleaner - but would require both builds to be imported which also isn't ideal.

Were you able to make this work? I've tried to reproduce the trex example and it did not work as expected
