The nb enchanted tree and nb sacred tree is insprred by MFR2 MOD. The tree growed by sapling which called nb enchanted tree, is bigger than nature generated which called nb sacred tree. The crown always at world Y 120 to 319, and the trunk will from sapling hight to world Y 317, it means crown may lower than trunk bottom when you plant the sapling higher than world Y 120.

Aften the enchanted sapling grow, you'd better to close your aechive and join it again, force the game do blocks update, deal with ghost blocks. The enchanted leaves don't drop sticks, to reduce dropping items.


Both Steel block, Coke oven, Black diamond block, Lonsdaleite block can block the Piston. Black diamond block and Lonsdaleite block has explode resistance as Obsidian.


The lite edition wouldn't generate the trees in world, but you can use with datagen datapack to config the generation rate. You can also directly uncompress and edit the jar form MOD file, they has the same content about data generation.

If you don't want generate specified trees, you can delete the relevant JSON files from \data\newbigtrees\neoforge\biome_modifier\ path. The code in files line 3 "biomes" can be seted if you know the biome id.

The JSON files in \data\newbigtrees\worldgen\placed_feature\ can be used to config the generation rate.

  • The generation rate in overworld and the end is a mixed number, the code in files line 10 "data" is the integer part, the code in files line 11 "weight" is the denominator minus 1 (15 means 1/16, 7 means 1/8, etc.),and the code in files line 14 "data" is the sum of the integer part and the numerator.
  • The generation rate of nether trees decided by line 6 "chance" in the JSON files, it is the denominator.

Recommended to install ferritecore MOD and ScalableLux MOD. Don't compatible with C2ME MOD and Lithium MOD. If you has installed Sodium MOD, better to keep "Performance / Thunk Update Thread" default, force max threads may cause out of memory.


You can freely use the mod in modpacks.

You can also edit and build the souce code to fit your modpacks.
