Nether and End regeneration



I’m a new user of paper (since 1.13 :wink: ).
I look for a way to regenerate Nether and End changing their seed and deleting coresponding map folders.
I was used to do it changing the level-seed value in, but it’s look like this value is’nt used. Instead it’s the seed of the overworld map that is used.
Did someone have solution ?

PS I’m french, i appologize for my poor english.


So really nobody has an idea ?? :fearful:
