Quand on se perds dans son ChunkProvider
-
Yop tout le monde,
C’est mon premier post sur MFF (j’etait sur Ironcraft mais ils aiment pas forge bon …).
J’ai joué avec les dimensions dans Minecraft et je suis arrivé a un résultat plutôt etrangevoila je trouve ça sympa pour ceux qui voudraient eventuellement :
