The Terraformer Blueprint (TFBP) is required to install various terraforming programs for the Terraformer. These programs include chilling, cultivation, desertification, flatification, irrigation, and mushroom.
You can remove the 'program' from the TFBP by placing it in your crafting GUI, however, this wil NOT work with the Mushroom TFBP.
TFBP - Chilling
Creates snow and freezes water. Warning! The Chilling upgrade can break planks and glass that were player placed and should be used carefully! Blocks can sometimes be replaced by snow as well, though this mostly occurs with Basalt blocks.
In the Nether, it will create snow on top of Netherrack, and will (strangely) not melt by pre-existing fires burning on top of them.
Max Input when 8x8 chunks are mostly terraformed at 200 EU/t.
TFBP - Cultivation
Tills the grass into plowed soil and plants crops, grows normal trees, rubber trees, flowers and pumpkins, it also turns sand into dirt.
TFBP - Desertification
Replaces dirt with sand, destroys all plants, melts ice and snow, and destroys water source blocks
Note: Warning! Can cause forest fires!
TFBP - Flatification
Removes all natural (overworld) blocks above the terraformer and fills the surface layers below with dirt. When placed below ores, the terraformer will only remove every block above an ore deposit and leave all blocks below the deposit down to the level of the terraformer.
It will not fill up holes filled with water. Use desertification first if that's what you want.
TFBP - Irrigation
Makes rain more likely in the area, rarely spawns water on the surface of the terraformer's layer, causes saplings wheat and sugarcane to grow faster and also allows sugarcane to grow above the 3 block limit, and easily turns sand into fertile dirt/grass.
Avoid having oak, pine, rubber or birch saplings near the terraformer as this will cause them to grow. It is unknown whether jungle saplings do the same.
Note: On servers, the likelihood to rain does not increase substantially.
TFBP - Mushroom
Converts all nearby blocks (except player-placed and stone) into mycelium. Also plants mushrooms, and makes them grow to giant mushrooms.
Note: Use with caution, as this TFBP is glitchy. It will convert giant mushroom blocks to mycelium, and will grow giant mushrooms on those.
Note: You can get Mycelium by placing 5 UU-Matter in a Minecart/Boat shape at the bottom of the crafting grid.
