32 The UUID is a 32 bytes array composed of ASCII characters; groups of letters should be separated by '-'. There are standard function calls to automatically generate this string depending on the tools used. |

34 This is however just due to convenience. UUIDs are not a particularly good source of entropy and any 1-249 character string can be used. If the string is of the form AAAAAAAAA|BBBBB (2 pipe separated strings) then only AAAAAAAAA will be used for terrain generation while AAAAAAAAA|BBBBB will be used for everything else. This allows players to use keep a terrain they generated but change the rest of the seed to ensure new positions etc. |
