Level Loading or Level Streaming?
Hi there, I'm new enough to UE4 to wonder what is best when creating an open world game. With things such as spawning Items and AI, is level streaming a good way to go about it or loading a new level? I like level loading because it's easier to manage and better on performance/realism. But level streaming looks better in the way that i wouldn't have to save game instance stuff for my characters variables. To someone as inexperienced as me, that looks intimidating. However, I've never seen a level streamed open world example. it seems that its mainly used for rooms that you cant see into. is there a way to show what the level looks like before entering the streaming volume so it actually looks like something is there? That way, i could divide my map up into sections and the player wouldn't notice anything different.
So which should I use for what I desire?

You seem to have a grasp of how they differ.
It really boils down to whether or not you want to have distinct transition points between areas, or to be able to walk from one to the next while still interacting with everything.
Enemy AI - for example, cannot follow you from one map to the next. (of course you could create a copy of it in the new map to simulate that it had)
Better examples each way tend to have both. EverQuest "zoning" was a distinct Map Load method - but they also used streaming within each map because they were large enough to require it.
And games like World of Warcraft are clearly streaming - but have areas where Loading to another map is necessary. (instances for example)
If you are making maps large enough to ask - you may want to consider using both.

I'm very new to this, but the only open world game that I recall to be an exception is Borderlands franchise, which runs on UE3, each location have a loading trasition, but there is no traces from the previous location on the new one.
However, games like Quake 2 and Half Life always carried a few parts of the previous map, and I think it also carried models and enemies if they were near you.
