Rubber trees are the primary source of Rubber Resin (NYI). They consist of Rubber Wood, which can have spots for extracting said resin and Rubber Leaves.
Occurrence
Their chance of spawning depends on the biome. They cannot spawn in Desert, Savanna, Hell, Ice Desert, Taiga, Tundra, Shrubland or Plains.
| Biome | Spawn Chance per Chunk |
|---|---|
| Rainforest | 1/4 (25%) |
| Swampland | 1/6 (16%) |
| Seasonal Forest | 1/20 (5%) |
| Forest | 1/50 (2%) |
| For other biomes not listed in the above table (for example those added by mods), the rarity is 1/100 (1%) per chunk if it can rain in the biome and the tree can’t spawn if it can snow in the biome or it can’t rain in the biome. |
