About this Mod

Secret seed setter

This mod allows you to override the random seed on world creation and make the world always set your custom seed

Setup

Put a file called customseed.txt in .minecraft/config/customseed.txt

It must contain only the number of the seed you want to set such as:

123456789

If you manually set a seed on world creation it wont override that, it only applies to random seeds (blank seed box)
