Change World Height

[willowillow]

I can't find where to change the world height for a dedicated server, the wiki page for world generation settings notes that its set at world creation, but don't explain or link to how. I found a MapSizeY value in serverconfig.json, but after changing it to 350 and deleting the world to regenerate I started receiving errors which disappeared when it was changed back.

The errors received are here:

When creating a new world, it’s found underneath the world name but above all the other settings, on all tabs except for the one for game mode.

MapSizeY is found in two separate locations in the serverconfig.json file, make sure to set both to the same value before creating the world.

sorry for necroposting, been busy

I found both of the MapSizeY in the serverconfig file, but it don't fix the error, I left both set to 350 anyways and it only caused lag and crashes, changing it back to default fixed it. I can't change it when creating a new world as I'm running a dedicated server and I don't have a ui to set initial world settings.

Thanks!
