I think we had this discussion, when it was accidental changed in c12…. Because we got used to the workflow with ids for individual source objects and not Forrest object.
If this source object could’ve maintained and the other would be an optional approach it would be fine. But I like to have individual mask for source objects (trees or furniture etc) to alter it in post.
If only Forrest pack is able to have a mask I’d, then you end up with many Forrest objects for various source objects.
Just as dj_buckley said it’s quite easy to select individual source objects and all apply them same id
