Does powernukkit support java worlds? custom imported worlds? mc bedrock worlds? please let me know
Not yet but it’s a planned feature. But you can use the Java2Nukkit World Converter to convert your Java world into a compatible format. Keep in mind that the current version has some limitations and newer blocks will get replaced by similar blocks since they weren’t supported when the tool were created.
Check the README file for instructions on how to use it. You need to optimize your world with Minecraft Java Edition 1.15.2 first. 1.16 is not supported yet.
Here’s a screenshot of how it looks after the world is converted, left side is the original Java world, right side is the converted world running on an old version of PowerNukkit:
