Hello. Nice to meet you, good morning. It's called bass_clef_.
Ask multiple questions.
Regarding the "customization" option that existed between JE versions 1.8 to 1.12.
With the update of 1.16 can deeper settings be made? You know that you can now export/import worldgen_settings_export,
Is the configurable item compatible with the "customize" option that once existed?
Assuming the first question is almost affirmative (the settings are different but you can do the same),
As far as I checked a little, it seems that Vanilla does not convert even if you take over the preset / world of 1.12 as it is,
I've developed a spigot plugin in 1.14 that brings back the "customize" option.
Is there a demand for something similar in 1.16?
English is a little, thank you google translation.
