Problems with generator

(sry for my English)
I want to ask for help, because I've tried a lot of ways to solve the problems with the generator of PM, and place my own seed to make my world better. But after changing it a lot of times, almost nothing appear to be different, and worlds are looking like they are made in the earliest beta versions of Minecraft.
Anybody know how to solve that problem?
WorldEdit and server.properties are not helping

 

I would be very thankful if anyone can help me

 

because the way pocketmine has its own generation method, it doesnt like the one minecraft current has, so u cant expected aw like in vanilla minecraft.

You can looking for some map on google to add it into ur server

 

You can try beta version of MultiWorld new custom generator

 

You can make your own world with the seed u want and then add it to your server that should work!

 

you can create workds in manyworlds plugin (download in pmmp.io) you can make :
/mw create Name Seed
