This looks amazing, I’m really happy you want to build out the functionality of Snap builder. I agree the building the Snap components in a Blueprint is a pain but honestly it does not seem that bad. You just can make it in a level then convert the whole thing to a Blueprint actor. I’m much more interested in better functionality of the snap builder its self. I would like to be able to use A Multi Dungeon custom layout with the snap builder in addition to a custom builder (like the straight line example you have). That would be huge functionality, also critical would be access to room and order information so we can better dynamically populate the rooms and hallways. I love the functionality examples you listed. I hope that all makes it into 2.8. Thank you.
