I'm working on an architechural visualization type project and using instantiate in an editor script to populate the world with objects exported from my CAD model, (wrote export script for CAD). The majority of my "game" world is instantiated this way via this scripting. When I'm instantiating prefabs, the instances don't seem to be updating when I change the original prefab. I am lead to believe instantiate is doing the same thing as dragging the prefab manually in the editor, but when it happens in the script, the editor doesn't know to maintain the link between the instance and the original prefab. I'd really like changes to the prefab to propagate down to the instances. Particular issue right now is tweaking LOD distances. When I change the prefab I have to re-instantiate everything to check settings, delete them all, adjust prefab, re-instantiate etc. It's taking me way too long to fine-tune this stuff. Possible? Ideas?
