I’ve been using these videos by @Clexarews and some of the other references on the forum.
And this reference was helpful.
There are other videos as well.
If you have any questions I have no problem helping you if I can. But I won’t be making how to videos as it to time consuming and I still don’t fully know what I’m doing. It’s a whole lot of trial and error.
Edit:
I haven’t created a whole world yet.
Only instances (prefabs) and biomes so far. But I am looking at the Halloween world file.
