Other World Generation

Tinkers' Construct also adds other world generation; specifically, the generation of ore bushes. Six bushes generate in the Overworld:

These Bushes can be reharvested after you break them. They can be replanted in areas where light levels are lower than 13. Similar to cactus, they damage the player if they are touched.

The ore berries they produce can be smelted into the respective ore's nugget.
