Haha. How big is your blueprint now? Did you notice an increase in file size with 4.7? My MapGen BP was 20-26MB in 4.6, and in 4.7 it ballooned to 88MB somehow. Even the portions I break off are far bigger than they would have been before. I am assuming this has something to do with the circular dependency fixes, but who knows what else could have beefed it up.
Just using empty actor BP’s for the new pieces. Their key info variables are exposed on spawn and set by the main BP. First thing I split off was the actual instance spawning section so that J.J could work in it without being weighed down by the rest. Right now I am working to push the map update functions(such as when I click the map to turn on overlays, remove forest, etc) from the main bp into the SpawnBP.
Also breaking things by function; tectonics(already separated, but still in testing), landmass creation, climate, river, etc.
The main BP will act as the gateway and holder of all information, and is now named MapState.
