How to use:

For versions 1.17.X and below:
– In the Overworld, explore until the mod finds a dungeon. The cracking process will start automatically. If it doesn’t give you a world seed, you may need to find another dungeon.
– In the Nether, explore the warped fungus biome until the mod finds a big fungus and starts cracking.
– In the End, find 5 or more end cities or end gateways, then return to the center of the end dimension to obtain the pillar seed. Cracking will begin after that.

For versions 1.18.X and higher:
– Dungeon cracking and fungus cracking no longer work.
– In the Overworld, go to the config menu using “/seedcracker gui” (1.19.3+) or “/seed gui” (before 1.19.3). Disable Emeralds, Gateways, Biomes, Desert wells, and Warped fungi since they are not updated and can provide incorrect data.
– To crack the seed, you now need to gather 40 bits of liftable structures and 32 regular bits from the listed ones: Igloo, Desert Pyramid, Jungle Temple, Swamp Hut, Shipwreck, Pillager Outpost, Ocean Monument. Any combination is valid. You can track your progress with “/seed data bits”. The cracking process will start automatically after you have enough bits. It may ask you to find additional structures. After reducing your structure seeds, the mod will brute force your world seed via dungeon positions or hashed seed.

Supported Structures

– Igloo – 9 regular and liftable bits
– Desert Pyramid – 9 regular and liftable bits
– Jungle Temple – 9 regular and liftable bits
– Swamp Hut – 9 regular and liftable bits
– Shipwreck – 8 regular and liftable bits
– Pillager Outpost – 9 lifable bits
– Ocean Monument – 9 regular bits

In the Nether, fungus cracking does not work anymore, so you cannot find a Nether seed using SeedcrackerX. However, you can try to crack it yourself using Nether_Bedrock_Cracker.

In the End, find 5 or more end cities to fill up regular bits. Then return to the center of the end dimension to obtain the pillar seed, and cracking should begin.

Make sure to disable end gateways.
