Tan’s Huge Trees mod (1.18.2, 1.15.6) is a mod for structure generation. Create giant trees and nature items in vanilla main biomes. This mod now has 49 structures. This mod will give your world a fantasy look without the need to add any blocks. You can only use vanilla blocks. These trees are not generated with coding, but they can be instantly crafted using sapling items. These structures will not be generated in the spawn chunk when the world is created for the first time. This allows for faster world generation. These trees can cause lag if you set the render distance to low or set trees to speed. To stop the fire spreading, enter this command into your chat: /gamerule doFireTick fals.
