How compatible are McMeddons pre-1.20 Worlds, with 1.20 (Patreon)

Welcome to this "Transparency Report". My worlds are by no means perfect and theres still work to be done to get it to vanilla parity. But i want to be as transparent as possible in terms of what is possible, what not, and what you can expect

With 1.20 many new features, items, blocks and structures have come out.

• McMeddons worlds have pre-rendered core worlds where every chunk is pre-generated.
• The worlds transfer after the "core world" into vanilla chunks where Minecraft takes over the chunk generation.
• To get the new features you likely have to head out into the wild, while for many other features, you can these via the loot tables from chests, barrels, and other containers that are scattered around the world. All containers in McMeddons world access vanilla loot tables.

I am working towards full capability with 1.20 for a seamless experience and hope to bring amazing new worlds to you in 1.20 soon!
