Need some help understanding level streaming and landscapes together

I have looked quite hard, and haven’t found much info on this subject for some reason. I have been looking into level streaming, and I haven’t found many good resources that are in depth. I saw a video on youtube but it didn’t explain much. What I want to achieve is an open world rpg. My question is, is it a good idea to use the landscapes with level streaming? And is there any really in depth documentaion on world composition, because the docs I read didn’t quite tell me what exactly it does. Maybe I am confused on terminology and all of this is easy to understand, but I just need some guidance on using landscapes, level streaming, and/or world composition for an open world RPG.

Thanks in advance for any advice you can offer :slight_smile:
