@Aeris•infinitus[prudens] Level streaming isn't instantaneous, the map still needs to load and because it's loading in the background it will take a bit longer than if you just did a loading screen. But this is just a small proof of concept to show how it's done, so it's pretty easy to break it. If you were making an actual custom story then you would be able to trigger the map preloading much sooner so the player never sees the void.

And I dont't know much about level streaming but in my case with an ssd the map took 3 seconds to load and I fell multiple time into the void because of that. Aside that good map interesting sights and well done loop.

in case of crash at lunch. Add; HeroStatsHandler = "base/HeroStatsHandler.hps"
RichPresenceHandler = "base/RichPresenceHandler.hps", in game.cfg like this:
<ScriptFiles
Player = "player/Player.hps"

InputHandler = "base/InputHandler.hps"
EventDatabaseHandler = "base/EventDatabaseHandler.hps"
GuiHandler = "base/GuiHandler.hps"
AchievementHandler = "base/AchievementHandler.hps"
HeroStatsHandler = "base/HeroStatsHandler.hps"
RichPresenceHandler = "base/RichPresenceHandler.hps"
route: C:\Program Files (x86)\Steam\steamapps\workshop\content\282140\545915343\config
