That’s the great thing about streaming. You can keep the camera in the persistent and just load levels as you scroll around.
Try this: You can make a new empty persistent level, then open the ‘levels’ tab ( window -> levels ). You can add a couple of your existing levels ( there’s an already existing option ).
You’ll see they appear in the persistent, just like you’ve opened the map, but they’re both in there at the same time.
You can work with a sort of grid area, big enough to have the camera scrolling effect, but small enough to be very manageable. Frankly 2x2 would do it.
You can turn the levels on and off with the eye icon next to the name.
Watch out, any changes you make here will actually affect your level maps!
I’m gonna go a look up static lighting with streaming in the meantime…
EDIT: Ok, checked. You need to use ‘lighting scenarios’, it’s a way of being able to build light in all the submaps:
I’d suggest trying it with a couple of simple sublevels first, see if it works and is efficient.
Tell me if yuo get stuck…
