Help with multiple levels/instances

Hello, I'm fairly new here and have still much to learn, so sorry if I mix up some definitions. Also, my English is not perfect unfortunately, so feel free to ask for clarification please if I'm not clear.

Right now, I'm trying to figure out if it's possible to create a Core game with multiple levels/instances. It would be a first person RPG, as open world as possible, but due to terrain size limit I think I'll need to be able to create more different levels/instances I think.

For example: can I have a desert level (max size) and then at all corners some exits? That once you trigger it, or walk through it, it loads up a corresponding level/instance? For when progressing the game to a different biome or when entering a dungeon, for example.

I found the Portal but if I'm not mistaken, that only allows me to go to a complete different game. I got that working but the loading time (finding server) can be high when transitioning. And also I read that it's not possible to transfer gear/inventory with character to another game, making it not really an option to use for different levels/instances I guess.

Is someone able to tell me if what I want is even possible? Or steer me in the right direction so I can figure it out myself please? Many thanks.

I'm also wondering about this.

Within Core, there aren't any scene options like there are within an engine like Unity. Instead, you'll have to plan entirely around the one scene you're given. Also, keep in mind, you can only have one terrain with collision, which makes your job a bit harder since you'll have to sculpt out your entire world on one terrain. For the size limit you mentioned, one solution might just be to increase the voxel size of your terrain which will make it bigger:

Or you could also fake scale by simply scaling down the player and all the world objects.

To portal players from one section of the map to another, 1) make your large terrain 2) then sculpt out all your different levels. You'll need to be creative with your design if you want to make each level feel different. 3) After that, then use portals to take them to the different areas on the terrain using something like my CC which will take you from the portal to wherever you place the cube:

That is one option to basically have multiple games where you transfer the player to your other game world. As of right now as you said, you wouldn't be able to transfer inventory, but that might change in the future as the Core team has mentioned maybe adding in persistent data. So keep up with new Core announcements and you might one day have that possibility.
