(the number comes from the , which is the 2b2t world seed + the magic value used for seeding the Woodland region (as shown earlier). For any other world you would just put your own seed instead into this equation.)-4172144997891902323-4172144997902289642 + 10387319

But how to get the server world seed from client? Minecraft.getMinecraft().theWorld.getSeed() returns 0 Thanks

There are seed cracker tools available for many versions, I would suggest using slime seed cracker and a world downloader mod
