I didn’t think I was entry level - I’ve used other DevKits and Game Engines in the past (Hammer, Unity, CryTech)… but I simply cannot work this out. Opening what’s called The Island just gives me the sea and a load of references to chunks (A1, A2, etc). However, opening any of them has scenery at best (like the rocks on top of Dead Island), or cave entrances…
I can’t find anyone else asking this, either, so I feel like I’m missing something insanely obvious - and that’s just making me feel more stupid.
Then all the levels in “TheIsland” will be visible in the Levels window. If your Levels window is not open, go to the top left hand side Menus, click on the Windows menu, and then select Levels.
Double click on the level you want to enable (see) in your editor window. You can see in my pic below what to activate to see the landscape for example.
