and that's about it.
Here's full details regarding it in the recent update:

- Added support for directly importing Minecraft Worlds into Neos
-- In order to import, you need to install Mineways (https://www.realtimerendering.com/erich/minecraft/public/mineways/) either into C:\Program Files\Mineways or under Tools\Mineways in your Neos installation
-- To import, simply import the folder containing your Minecraft world (import the folder containing the level.dat file)
-- Alternatively import on the headless using importMinecraft <path to world> command
-- Neos will import all chunks with actual block data. For large maps import can take pretty long (dozens of minutes), but you'll be able to interact with the map as chunks of it import
-- Neos will setup and customize all the materials, collisions as well as a culling system which will only load meshes and render chunks within distance around the player to support large maps efficiently
-- For older maps, Neos will setup point light sources for torches (might turn this off if it ends up too heavy). For newer ones this isn't currently supported
-- Importer source code available for reference (and contributions) here: https://github.com/Neos-Metaverse/Minecraft2Neos
-- Please note that this isn't a fully officially supported feature, but something done for fun. Feature requests and bug reports won't likely be fullfilled unless we want to work on them. We might separate this into a separate optional importer plugin in the future.
