Ok, I would like to have the main outside world in my game (it's a massive city) to be within a single scene, with all indoor environments being in different scenes. I would like to know peoples opinions on this, I imagine people will advise using multiple scenes for the city, but given the new hardware in the upcoming XBox and Playstation consoles I was wondering if there would be a significant reduction in load times now, so I could literally load the city on the splash screen on both consoles and PC. I am trying to use depth of field and ill be also trying occlusion culling to reduce the load on the systems resources, coupled with the Volumetric Fog im using it should hopefully be quite optimized. I wanted to ask this question now before I start developing massive chunks of the city so I know what method i'll be using to build the world. So would keeping the outside environment in one massive scene be do-able or should I always break up the city into loadable "chunks" for optimizations sake?, probably worth mentioning that theres a lot of neon signs (emissive materials) and volumetric lights in places also.
