Changing the world generation option on an already created world

[WILK 505 camciaru]

is it possible to change the world generation option, such as land cover on an already created world?

I found a command that changes the land cover "/worldconfig landcover [0.1-1]". Will it generate new chunks that are not generated according to the new settings?

I need this because, I don't know how, but when I created the world, the terrain coverage was set to 0%. It created a really nice island, but there's nothing around it except the island.

Is there any other way I can change the terrain generation in unexplored areas?

Never mind. It works. But you have to fly away in repair mode to a really big distance. It will start generating new terrain which will be connected to the old one with a straight line like from a knife cut.
